Dear Doctor: I have a 1999 Buick LeSabre with the 3.8-liter engine, automatic transmission and anti-lock brakes. When I accelerate too quickly from a stop I get a severe vibration in the front wheels that continues for a couple of seconds. The vibration feels like the wheels are not turning, but skipping. The same thing happens at slower starts if I’m driving on an incline. Do you have any advice on what I should look for? Larry
Dear Larry: The first thing is to determine whether the problem is based in the traction control system. This can be done with the use of a scan tool or by disconnecting the anti-lock brake main power wire at the ABS unit for testing purposes. If the problem is still present, then the next steps are to check the transmission and look for worn front axle c/v joints. A weak engine mount can also cause the engine to move enough to also cause the vibration you describe.
