Rear end
Hi there,
Per GM VME, we are under strict orders, unless you are doing an end cover seal, we CANNOT overhaul the rear differential on the c5.
The reason is that we cannot set the correct side carrier preload, because the jig is like 1500 dollars, and has NOT been sent to any dealers as of yet.
Personally, by an entire unit, and then proceed with the install.
I caution that after you had the alignment done, this noise started, I feel that maybe you should get a seconde opinion here.
Another thing, does the noise change pitch when you accel or decelerate the car?? Is it sensitive to engine speed, NOT vehicle speed?? Does it sound louder when you are just cruising, or when you are really on it??
Let us know, c4c5
