Rear Grinding Sound/High-Pitch Barely Audible Whine
 

Hi Again All,

In addition to my 1996 V-* rear kick I mentioned in a concurrent post,
I have grinding (more like groaning) noise that is speed sensitive,
about 1 groan every 3 or 4 meters. Also, while driving on the
highway, the groan is persisent, but at those speeds, you cannot hear
the individual revolutions, just a loud hum/growl (hard to explain).
Also, there is a noise that is a fine, high-pitched whine, but not
very loud, at least not as loud as the hum.

What is this?

Sounds a bit like the "carrier bearing growl" on my 97. Seems to be
more obvious on vehicles with Trac-Loc because the nature of the groan
changes depending on whether the vehicle is turning left or right.
Made quite a difference on mine - even when the curve was fairly
slight.

The TSB for the 1997 Grand is:

I'm guessing your '96 V8 is sitting in a Grand Cherokee with a bent
aluminum housing, from the use of a floor jack.

Hey Bill et al,

I guess I failed to mentioned that the whining sound is coming
undeniably from the rear.
