Knocking from front end only when accelerating

**Gonk24** · 12-14-2009

Getting a wicked knocking vibration from the front end only when accelerating. I've had this problem for quite a while now and just changed a bad hub 2 weeks ago hoping to fix it. It didn't. Being that it only knocks/shakes when on the gas, what else could it be besides the CV/axle?

Hello Gonk 24...Were you able to isolate or pinpoint the problem? I am having similar problems with my 2002 Grand Prix. I have changed the transmissioin mount, drivers side CV halfshaft, and I am soon going to change the ball joints along with the passengers side CV halfshaft. I hope that I don't have replace the hub bearing assembly. The bearing on the drivers side felt very tight and that is where I am feeling the most vibrations.(DRIVERS SIDE FLOOR BOARD)

my car does the same thing, but only when the suspension is depressed on acceleration.

Mine used to do this, REALLY BAD. Just took it to my mechanic today and he replaced both c/v axles and now it drives as smooth as a benz (exaggeration lol).
