I got 4 new struts and front half shafts replaced with front tires balanced and 4 wheel alignment. I notice a noticable vibration when acclerating between 30-50. They replaced the wheel bearings and it helped a little. What else good be that problem?

 

your paranoid..

 

I wish I were, but the mechanic noticed the same problem when I took it in and they thought it could be the wheel bearings which they replaced.

 

Vibration when accelerating may be coming from your engine. A weak cylinder or misfire will cause that. Does it feel like the whole cars body shakes or just the steering wheel?

 

Could be motor mounts.

 

Stangely enough, just the vibration from the acceleration pedal around 30-50 mph. Was fine before the cv shaft and struts

 

Where did you get the halfshafts from? I think alot of companies just slap on new boots when they rebuild them, but the joints could worn, especially the inners. I really think it's your halfshafts. Where they new or rebuilt?

 

They were rebuilt ones from advance auto parts.

 

Does the vibration really feel like it's coming straight from the floorboard more than in front of you (engine)?

Then they were rebuilt wrong.

Inboard joint on either axle.

its just Torque

 

Very helpful thread! I hope it's just the inboard cv joint. I loved the smoothness before replacing the cv shaft. I'll have them check it out.
