03 trailblazer front vibration
 

I'm chasing a front right side vibration/hum that gets louder to a groan on left turns. I've already replaced all the obvious, front right wheel bearing hub (twice), front right CV axle, and the 4x4 disconnect assembly. Ive also swapped the tires around and the vibration is still there. I'm outta ideas, anything you guys can suggest would be much appreciated. Thx.

I just had the same problem, when I turned right it was like a metal on metal grinding and I had to replace both the right and left front wheel hub assemblies and bearings

I would do the left. My hubs seems to be bad on the side I am turning toward when the noise increases oddly enough.

Does it vibrate all the time?

Is the diff fluid in good shape?

Ive had this similar issue for quite some time too. Ive narrowed it down between the half shafts and output shaft on TC. Im wondering if it the bearings in the axle itself.

Got to the bottom of it. Replaced the right side hub/bearing assy again along with the upper ball joint which was totally shot and still had a vibration so went ahead and replaced the same on the left, ball joint not as bad but needed a new one, and that did the trick. No more vibrations. Now on to the TPS problem, but that's another thread. Thx for the help.

Sorry to bring up an old thread. Im thinking my inner axle bearings may need replaced. I do have a small leak at seal on right tube where cv axle goes in.

Is anyone have info on replacing those bearings? I believe there are 2 bearings in the tube.

You have a Blazer or Trailblazer?

On my Trailblazer...I have done the seal on the DR side and rebuilt the disco on the PS side with new bearings and such.

Sorry I posted in wrong section. But yeah I have a 2nd gen blazer.
