Automotive Vibration Troubleshooting - The Three Types of Driveline Vibration

There are several different possible causes for a driveline vibration. Your wheels, tires, axles, driveshaft, transmission, clutch or torque converter and engine components are all rotating at a high rate of speed, and any one or more of these components can create a vibration if they are worn or out of spec. Worn or broken engine or transmission mounts can transmit normal vibrations that usually aren't ever felt, and accidental body contact with the engine, transmission, or exhaust can also be misinterpreted as a driveline vibration. The first step in diagnosing a classic car vibration is to determine exactly when and under what conditions the vibration occurs.

 There are three basic types of vibrations:


 1. Engine RPM related - If the vibration is related to engine RPM, it will occur in all gears (and possibly even sitting still) at a particular engine RPM or above. This vibration usually can be attributed to the engine itself or anything else that turns at the same speed as the engine, such as the harmonic balancer, flywheel or flexplate, pilot bearing, pressure plate, torque converter, or transmission input shaft. It is also possible for body contact with the engine, transmission, or exhaust to cause an engine RPM related vibration. Worn or broken engine or transmission mounts can contribute to this problem. When driving the vehicle with the vibration present, maintain vehicle speed and try shifting to a lower or higher gear. If the vibration changes or goes away while maintaining the same vehicle speed, then the problem is not related to engine RPM.

 2. Vehicle Speed related - If the vibration is related to vehicle speed, it will not be present until you reach a certain speed, and then it will usually start gradually and then become worse as speed increases. In some cases, it will decrease at some point, and then come back again at a higher speed. This type of vibration could be related to your wheels, tires, axles, differential, driveshaft runout, balance, or angles, universal joints, or transmission output shaft. Try the same driving test as above. If the vibration is present in third gear at 50 mph, but shifting to fourth gear at 50 MPH makes the vibration go away, then it is not going to be vehicle speed related and you can usually rule out any rotating component that is further back than the transmission output shaft. At a given MPH, your output shaft, driveshaft, axles, wheels and tires are all turning at a constant speed, no matter what gear the transmission is in.

 3. Accel/Decel/Cruise related - A vibration that changes depending on whether you are accelerating, decelerating, or cruising at a steady speed could have quite a few different causes. Generally, this will be related to driveshaft angles or a worn or broken part, instead of something being out of balance. Think about what changes when the engine is under load. The engine and isolator mount loads shift; the load on the pinion bearing changes; your driveshaft angles change, possibly more than they should due to a broken engine or transmission mount; your exhaust, shifter, transmission, etc. could be contacting the body only on accel or decel; if the car has been lowered (or raised), your suspension snubbers could be contacting the body prematurely.

 A vehicle works as a system, and you have to understand the relationships between all the different parts when you are trying to diagnose a driveline vibration. Determining if the vibration is related to engine speed, vehicle speed, or engine load will help you narrow down the list of possible culprits, and keep you from wasting your time looking in the wrong places.

Auto Insurance in Iowa

The state of Iowa does not require that all drivers have a liability auto insurance policy. Unlike most other states, Iowa does not have a compulsory insurance law for drivers. However, the law requires that the driver as well as the owner of the vehicle, be able to show financial responsibility.

 Iowa is not a -no-fault- state where a determination as who caused the accident, is discovered and settled through the Tort legal process. In other words, if there is an accident, one of the drivers will be identified as the cause or at-fault in the accident. And being at fault must pay damages. In most cases, the auto insurance company of the person at fault will pay the damages. Because Iowa is a Tort state, most insurance companies recommend that driver's consider carrying higher coverage than just the state minimums.

 In the state of Iowa, all motorists must show proof of financial responsibility to peace officers upon request. The most common way is to purchase a valid liability insurance policy. Once the policy is issued, your insurance company will send you an insurance card, which you will keep in the car, at all times.

 Iowa's Financial & Safety Responsibility Act provides that drivers who drive dangerously, as well as not being able to prove financially responsibility, can lose their driving and registration privileges terminated. Once that occurs, they will have to prove their ability to pay for any destruction of property or injuries caused.

 In circumstances where the driver or owner does not have auto insurance, they can contact the Office of Driver Services at (800) 532-1121 for submission instructions, to learn of the alternate forms of proof of financial responsibility that can be used.

 The state of Iowa has established the rules and guidelines, for allowing car insurance companies to use the personal credit history of the driver, to assist in determination of rates and products to offer. The rates are calculated based on factors including the age of the driver, the car type, driving record, location of residence, as well as the marital status. And those drivers with accidents and tickets on their driving records pay more than those with good records.

 In Iowa, the minimum liability coverage required, is bodily injury coverage of $20,000 per person, up to $40,000 bodily injury coverage for all persons per accident, and for property damage coverage caused in an at-fault accident, $15,000.

 Auto insurance companies operating in Iowa must offer uninsured and underinsured motorist coverage, where the driver has the option to buy it. Iowa insurance providers also offer collision coverage, comprehensive coverage. Because Iowa is a Tort state, consumers would be advised to buy additional coverage.

 In Iowa, there are rules regarding whether a driver has prior insurance. If your insurance lapses and you are operating a car, technically you are driving without insurance. If you are found to be driving without insurance, you will receive a citation and be fined. If an accident occurs, you will be fined and your license may be revoked, possibly for one year.

Ford Falcon AU XR6 Tune Melbourne Dyno Tuning Melbourne

Today we are looking at installing a Wolf V500 Plugin Engine Management kit on a Ford Falcon AU XR6.

 In the past, to put any kind of engine management on a Ford AU, you would have had to have either wired it in as a stand alone ECU (where you would lose some dashboard functions), or piggybacked it so that you kept all of the Dashboard and Climate Control aspects of the car usable.

 With the V500 Plugin Engine Management Kit, you just plug it in. All of your dashboard remains the same, you have a working temperature gauge, the climate control is working, and we use all of the factory standard sensors.

 The original ECU (Engine Control Unit) is located behind the passenger side kick panel.

 To remove the ECU, unclip the kick panel, remove the screw which holds the ECU brace on, and the ECU will then move freely from the kick panel.

 Use a 10mm socket to undo the bolt holding the main connector and ECU together. Remove the earth strap screw to remove the earth strap from the body of the car. When the V500 is fitted, we will use an earth strap that is part of the V500 Plugin harness, and attach it to this same spot.

 To fit the V500 Plugin Engine Management Kit, remove the V500 ECU and Plugin Loom from box, (there are programming cables and disks that we will use later for tuning).

 Notice that the Plugin harness has the same connector as the original ECU.

 You can now plug the connector in and do up the bolt in the middle of the connector. While you are doing up the bolt, support the connector with your hand so that when it is done up tight, you are not putting strain on the wires or connectors in the harness.

 Now use the original screw to attach the earth strap for the Wolf V500 and the original earth strap for the vehicle to the chassis of the car.

 The V500 ECU can now be plugged into the Plugin harness.

 There is one more thing that we need to do. You will notice on the Wolf V500 there is a vacuum port. We need to hook up manifold vacuum to the Wolf ECU.

 On a Ford Falcon AU, the easiest place to route a vacuum line is through the rubber body grommet where the original wiring for the vehicle runs through the fire wall.

 To access that, remove the washer bottle from the inner guard, disconnecting the electrical and water fittings.

 Now you have access to the body grommet that has indentations that you can punch a hole through with a screwdriver, and pass the vacuum line through.

 Use a thick walled vacuum line so it cannot be squashed by the body grommet, and can handle your intended maximum boost pressure. Make sure you connect your vacuum line to a constant vacuum/pressure source, for example, a fuel pressure regulator generally has a constant vacuum source. Do not source your vacuum from a wastegate line, as it may have a bleed off valve that can have different vacuum/boost compared to the true vacuum/boost that the engine is experiencing.

 Once you have run your vacuum line through the body grommet, replace and reconnect the washer bottle.

 Back inside the car, open the glovebox, put slight inward pressure on both glovebox walls to allow you to lower the lid even further down than normal to give you greater access to behind the glovebox.

 With long nosed pliers you will be able to pull the vacuum line through further. You will want to pull around 1 meter of vacuum line through the body grommet. That will allow you to run the vacuum line down behind the glovebox and around to the Wolf.

 Make the vacuum line just long enough that it can be connected to the Wolf V500 without it having to be looped around where it may get caught or kinked or crimped when the Wolf V500 is in place.

 Push the vacuum line over the barb fitting. If you are using thin walled vacuum tube, you might want to use a small hose clamp or cable tie to ensure it will not come off the barb.

 From here, the igniter, ECU and harness go into the kick panel from where the original ECU was removed. The kick panel is then placed into its original position.

 To get best access to the serial connector on the V500 is to run the communications cable up into the glovebox, where it is easy to connect to your laptop.

 Now you have installed your Wolf V500. The benefits to doing this are that you can control ignition timing, fuel and boost control. We have full control over the dashboard so that the air conditioning works, the temperature gauge works (the temperature gauge is normally disabled when you remove the original ECU), the engine check light works.

 The bonus to doing it is, that in a case where the car is modified, for example, adding a turbo or supercharger, or any other engine modifications,
 you can now tune the car to get as much power as the engine package will allow, while still maintaining drivability and using the car as a daily driver.

Every Little Thing You Should Learn About Lansing MI Car Repair Technicians

It's not unusual for car owners to hold off upkeep service. All too typically, little automobile issues snowball into huge ones until repair costs run in the thousands. Some criticize their busy schedules; others the expense. However you must bear in mind that vehicle upkeep is something you ought to constantly find the time and cash for.

 Lansing MI car repair specialists understand that most individuals simply wish to get a auto but few want to take care of its maintenance. They commonly state that if car owners just paid very close attention to early indications of problems and kept to their automobiles' upkeep schedules, they would find that some usual sources of auto breakdowns are surprisingly easy to prevent.

 Flat Tire

 One common cause of roadside automobile malfunction is a flat tire. While this is sometimes caused by a nail or a sharp item on the ground, in numerous various other instances, this is because of severe tread wear or unsuitable tire stress. Both situations can be prevented with preventive care. Always follow the tread depth recommendation of your tire manufacturer and the pressure requirement showed on your automobile owner's handbook.

 Engine overheating

 Engine overheating is very serious as it causes damages to the interior components like a busted head gasket, a split head, a warped engine block and damaged piston rings. Typical reasons for these are a stuck thermostat, a cooling system leak or a clogged radiator. To prevent troubles with the engine's cooling system, yearly inspections should be accomplished. Coolants, antifreeze and rust inhibitors should also be changed frequently.

 Engine wear

 Running an engine with little or no oil leads to significant damages so oil and oil filter replacement ought to never ever be ignored. Some vehicle owners do not understand that the engine oil acts not just as a lubricant but also as a coolant too so it is necessary that it's maintained at maximum level. Periodic oil modifications will enhance pressure and cause engine failure that might need you to change the whole engine. Regular oil changes by Lansing MI car repair and maintenance professionals can reveal if there are any oil leakages or oil pump malfunction.

 Maintenance services may be undesirable however investing funds on them now saves you much more later. Follow upkeep routines closely to avoid a breakdown and to lengthen the life of your automobile. A car upkeep list can be found at nationwide.com/rss/car-maintenance-tips.

Biodiesel Vs Recycled Vegetable Oil Fuel

With high gasoline prices and a focus on energy independence, alternatives to petroleum based fuels are gaining popularity. Biodiesel and recycled vegetable oil fuel are often presented as environmentally preferred alternatives to petroleum fuels, but what are they and how do they compare with each other?

 Biodiesel refers to a vegetable oil or animal fat-based diesel fuel typically made by chemically reacting lipids such as animal fat or vegetable oil with an alcohol to produce fatty acid esters. Biodiesel can be used in standard diesel engines, alone or blended with petroleum diesel and can also be used as a lower carbon alternative to heating oil.

 Vegetable oil can be used as an alternative fuel for diesel engines and heating oil burners. Most diesel car engines are suitable for the use of straight vegetable oil with appropriate modifications otherwise poor atomization and combustion of the oil will create carbon buildup that will ultimately damage the engine. Either new, clean vegetable oil or reclaimed vegetable oil can be used but recycled vegetable oil is perceived as a more environmentally responsible alternative.

 The sustainability of biodiesel fuels is under debate as the land devoted to bio diesel crops results in a net loss of food crops and there is some argument about the ratio of energy used in growing biodiesel crops compared to the amount of energy received once those crops have been refined into biodiesel fuel. Straight vegetable oil fuel can lay claim to higher sustainability because recycled vegetable oil can be recovered from businesses and industry that use the oil for cooking in deep fryers, snack food factories and restaurants.

 In 2009 ConsumerReports.org performed a test of biodiesel and vegetable oil fuels using a 2002 Volkswagon Jetta TDI and compared fuel consumption and accelerations, emissions, and ease of use. Biodiesel yielded marginally better mileage and acceleration and produced almost 20% less hydrocarbons (3ppm compared to 14ppm). Vegetable oil produced less particulates and NOx emissions. There is no difference in the amount of carbon dioxide produced no matter what liquid fuel an engine burns.

 Consumer Reports determined that biodiesel is significantly easier and more convenient to use as an engine fuel than vegetable oil. Vegetable oil requires engine modifications, sacrificing trunk space to carry an auxiliary tank, personal time and effort locating fuel sources as well as time and labor picking up the vegetable oil, filtering and storing it. In addition, even if you use vegetable oil fuel you still need to start the engine using diesel fuel after every drive and cleaning the system before shutting it down.

 At first glance, the idea of powering your car with recycled vegetable oil may appear as if there are no negatives, but the positives of using a recycled fuel and exhaust that smells like potato chips may not outweigh the significant personal time investment that is involved. If your primary concern is air quality and carbon pollution, the minimal differences in emissions and the zero difference in carbon dioxide production may affect your decision.

Replacing Car Body Panels, What You Need To Know

Your car is more than just a means of conveyance because it also says a lot about your personality. If your car has been involved in an accident and has been damaged quite a bit, you ll need to buy new car body panels in order to replace the old ones. Your first instinct might be to see if a mechanic might be able to straighten the dents and out and cover up the scratches, but this is not always possible. If the damage is extensive then replacing the ruined parts is your only option.

 There are many scrap yards that sell car parts at extremely low rates. Unfortunately, the car won t look entirely new even after the mechanic has welded the cannibalized parts from a scrapped vehicle onto your car. The low prices might also be offset by the cost of renting another vehicle while your car is in the repair shop, because this option simply takes too much time. If you do go for this option, you should check the parts you purchase to ensure that they are not rusted or damaged.

 Dents are relatively easy to sort out but rust is another matter altogether. You ll also have to check the vehicle to ensure that its mounting points are aligned correctly, else the new body panels you have purchased will not fit well and you will have a lot of maintenance problems with the car in addition to the fact that it will not look good. Make sure that all repairs are done before you install the parts.

 You ll find that new car body panels made by the manufacturer of your car will be a far better fit than anything else. Besides, you won t need to leave your car in the mechanic s shop for too long.

 It is obviously best if you use genuine parts on your vehicle even if they cost more. There are quite a few retailers, especially ones that are available online, who will offer you authentic parts at a very good price. In addition, your insurance company won t have a problem with paying for these parts as long as they are genuine, making these the best option.

 You should find a retailer who can supply you with any type of car body panels and other spare parts that you need in order to repair your car. Parts purchased from a reliable retailer will last for a long time and not give you any trouble.
