Hi there. It sounds like you have a wheel bearing or axle failure. A failing wheel bearing will generally produce more noise when loaded; LF when turning right and RF when turning left. An axle can produce similar noise if...

Hi there. It sounds like the valve cover gaskets are what is leaking. The gasket is made of rubber and can become hard and brittle over time and start leaking oil. The leak may not be one where it is...

Hi Angel. Thanks for contacting us tonight. Usually, when a car jerks while it's driving or during a shift, it's due to either a fuel/ignition problem with the engine or a restriction of transmission fluid. The coolant leak is likely...

Vehicles go into limp mode when the computer detects a possibility of damaging other components if you continue to drive it in the current state. Because of all the variables that go into diagnosing a drivability issue and given the...

The AC system could be low on refrigerant. Vans that have rear AC hold much more than a standard system. There are however, many more possibilities. Restrictions in the lines and blend door issues could cause this as well. I...

To diagnose this you can check for battery voltage at the horn terminals when you activate the horn button. If voltage is present, the horn is defective. If no voltage is present, trace the circuit back to the battery and...

From what you are describing it sounds like you have either a failure in the transfer case or in the front axle actuator. I usually drain the fluid from the transfer case first and check it for metal. If there...

If your brake fluid boiled during this or any past overheating incidents, then yes, the fluid is likely contaminated with air and other gases. Brake fluid is hygroscopic, and a consequence of that is when the fluid gets hotter than...

Diagnostic trouble code P0700 and code P0731 indicates that there is a fault in your car's "automatic transmission control system". Although there could be a faulty "part," (such as a shift solenoid or speed sensor), there are some preliminary checks...

No, the alternator provides voltage to the battery and other components. The PCM could possibly discharge a battery if it leaves a relay or another circuit on, but most likely is is not the cause of your alternator failure. If...

If the car is still overheating, even after filling the coolant system (and making sure there is no trapped air, which itself will cause overheating) just request an overheating diagnostic during which a certified mechanic will determine which of the...

Hi there. From the description you have provided, something was reassembled incorrectly. Not replacing the upper intake (plenum) gaskets should not have caused the vehicle's no start condition. Once that you have the plenum removed, carefully inspect all the components...

The most common cause of this is a failing ignition switch. For the ignition switch to allow the key to turn, it looks for the car to be in Park or Neutral. When the car isn't in either of...

The seat belt comfort guide can be used to adjust the shoulder strap on the rear outboard seat belts. It should be used when an occupant is too short for the seat belt, and the belt is resting near the...

The turbo resonator on 2004-2007 models fail chronically with symptoms as you describe. The original resonator is a 2-piece plastic assembly that de-laminates. The replacement part should be aluminum.

Hi there. In most cases, if this happened all of a sudden and went away after a moment, then it may just be low on oil or it may need an oil change. I would check the oil first. If...

Hi there. A miss under load indicates a secondary ignition problem. Your ignition system is divided into two components: the primary and secondary. The primary side of the system includes low voltage items including the battery, ignition switch, control module,...

Hi there, thanks for writing in about your 1982 Ford F-100. The new modulators may be to blame if the parts are not exactly like the original one and made somewhat the same way. This can lead to improper performance....

Hi there. This is one of those rare cases when Chilton got it wrong. The PCV valve is actually located on the other side of the engine in the back and near the firewall. It's located in the rear of...

Hello, if the car is only overheating when it is not moving then it is usually caused by an air flow issue through the radiator. Most of the time, this is caused by an issue with the radiator fan not...

In general, the engine vibration you're referring to is caused by a restriction of fuel flowing into the engine. This can be caused by dirty or clogged fuel injectors, a bad idle control valve, or the throttle body being dirty....

I would recommend starting by checking to see if the fuel is reaching the spark plugs. Try pulling one of the plugs out after cranking it over to see if the plug is wet with fuel. If they are not,...

You have the Chrysler 46RE transmission. Among the possible causes of what you describe is a rear servo piston that is sticking or broken, pin bore wear and/or the reverse band is slipping. The servo piston on the 46RE has...
