Front end Vibrates while accelerating by 2xracing

I have a 2001 GP GT and when I accelerate I get a vibration in the front end, it is worse if I am turning to the right and accelerating. I am thinking it is the transaxle or a wheel bearing assembly. Any help would be appreciated.

Could be a constant velocity joint as well.

I wish I could help but I have the same exact problem in my 02' and checked my CV shafts. Not a bit of play in them. Mine is really bad when I accelerate even a little and turn right. When I turn left and accelerate hard or soft it doesn't shake at all. Just fine when going straight! I'm just going to be like Kevin Harvick in the commercial..."Still not going to turn right are you....Nope!"

I found out that it is the C/V shafts are bad on mine, lot's of grease around them so after checking them there is a lot of play so I am going to replace them. As for your problem I checked with my brother in law who is a ASE mechanic and he told me on mine that if it wasn't the C/V shafts he would check the tie rod ends to see if there was any play in them, evidentely they tend to get loose over time. Just a suggestion. Good Luck and keep turning LEFT!!!!!!

My 2000 GP GTP sounds like it is doing the exact same thing. I recently took it in to a dealer and he said it needed a "tune-up," well it got tuned up (new plugs, wires, etc.) but it still has the "shakes" when I accelerate b/t 35 and 55 mph. Do you think it is the C/V joints as you said or something different?

It sure sounds like it. If you look around by the boots if you see a bunch of grease or if the boot is torn then more than likely that is your problem. Also if you jack the front of the car up and grab the wheel and move it back and forth look to see if anything "like the tie rods" are moving because it could also be the tie rod ends are bad. Good Luck!
