Front end shaking while acceleration

**Libke57** · 12-07-2016

Friday I noticed a bad vibration in the from end. Took drivers front tire off and didn't see anything so i put the tire back on and drove with no issues for 40 miles. Ran codes and it said the front bearings were bad so I replaced both. Car drove great for about 75 miles, smooth as could be, then the vibration came back. Only vibrates when I am on the gas, quits as soon as I let off the gas. Noticed a little play in the passenger cv shaft but was told it's not bad enough to cause any issues.......? It's a 2006 grand prix gt, stock. Please help

I'd guess cv shafts. Same symptoms I had when mine went.

CV.

Do you have to separate the ball joint to get the cv shaft out?

Yes, if you choose to do it that way.

It's the best way to insure you don't mess up the front camber somehow. Some will remove the strut from the knuckle but the ball joint way is the better way to me.

I had the same vibration. Replaced the passenger axle. Same thing. Ended up replacing the drivers and and when I was pulling it out it all fell apart. That fixed the issue.

Also, apparently NAPA reman axles use stock axles as a core so that's sorta good instead of getting junk Chinese stuff.

after changing a cv shaft do you need to get an alignment...???

**Fivefingerdeathpunch** · 12-08-2016

If you do it the ball joint way, no you do not need too.

If you remove the knuckle to strut bolts and don't get it back exactly where it was before you can throw it out of alignment sometimes.
