Question about Pontiac Grand Prix

1 Answer

I have a 2000 Grand Prix, 3.1, Automatic. Upon semi hard acceleration, I feel 3 thumps from the RF. My first guess is CV joint/RF axle. Car has 116K. It appears the axle has been replaced before. Thoughts or comments would be appreciated...

To test the CV joints make a hard right circle and then a hard left one. You dont have to do this at a high speed and you can do it in a parking area. IF you hear clunking then it is the CV joint.

2002 grand prix front tires are wearing out on the inside tread ?


It could be either the ball joints or the tie rod ends are worn out. With it being a front wheel drive car also check your drive axles. Make sure that the axle boots are not torn or cracked which if they are cracked or torn replace them and repack the cv joints.

How can you tell if the cv joint is gone


Usually there will be a loud clicking when you turn the wheel from the side that the CV is worn. Lift the car up and you will see the drive axle going to the transmission and the other end going into the hub on the wheel, In between is a rubber boot, inside the boot is the constant velocity joint (CV) Hold the axle on either side of the boot and see if you can feel any play in the joint when you move it around. If you can the CV needs replacing. Good luck.

A loud thump is heard when pulling away from a curve, making a


More than likely you do feel it in the wheel. My best guess is that it is than rack and pinoin bushings. If you can reach the rack, when the car is cool, see if you can have someone turn the wheel back and forth while the car is sitting still. If you feel the rack move, that is your issue. the reason it would do it during acceleration is because of touque steer.

It does sound like one of the universal joints. If you can raise the back end off the ground engage gear and the faulty u/v joint will make the wheel jump. This will let you know which side it is

Front end vibration


this is most often caused by worn out drive axle constant velocity joints or CV joints as we tech's call them, have them checked for torn boots or excessive wear, I am sure one or both will be found.
