Hello and Help!!!
I have a 2007 Chevy Tahoe LT 5.3 flex.
Now I have a "grinding" sound coming from the rear "axel", from what i can hear it comes from the right...
It's when I turn right and some time when going over speed bumps w only the left wheels.
The "noise" is not all the time it comes and goes. Can drive for hrs and nothing and then its "there" in all right turns. And harder/lauder when turning hard.
What I done, so far is. Changed brakes, rotor, the clip on the axles, checked the "dust plate", checked/renovated parking brakes.

 

Could possibly be a wheel bearing. If when turning right it gets louder it's the left bearinrg and vice-versa.

 

Will change the bearings, just in case... the only thing left to change. The "sound", I'm pretty sure comes from right side when turning right. Hade a friend "hang out" the window and listen.
I just thinking.... Watt if the bearing, on the right side is bad in the "bottom" and maybe even stuck. Then when driving strait there is "no" pressur on the bottom, but when turning right the wheel "hangs" on the bottom part of the bearing..... And making "the noise". Just a thought.

 

Like a mechanic friend of mine says " If one side fails the other side will follow. Might as well change both sides.

 

Yes, thanks! I always do both sides, on everything that has, are on two sides...

 

07 burban 2wd. Mine just whines like nothing I have ever heard. I checked fluid it's all good, a friend told me these years the rear end was assembled in Mexico and lots of problems w them so they moved it back to America. Reading here maybe it's bearings, but truck only has 100k, kinda unusual for that low milage. At 70 its screaming but dosnt seem to be getting worse. I was gonna try and source another complete rear end. Appreciate any advise guys....Roost

 

Good afternoon,

I have a 07 Tahoe LT, 5.3L v8 2wd. I recently got the rear end rebuilt, and now I sometimes hear a clunk, or pop when accelerating. I am thinking the backlash is not quite right, but wasn't sure if the teeth in the axle shaft are worn and if this would cause that popping noise? Any help in a direction for insight would help, thanks in advance.
