If your diff has been whining, let us know at what speed and mileage did it start?
(ie; at 400 miles between 50-75)

What mileage did it start to get louder? And what mileage was it changed?

Any mods? Burnouts, wheel hopping?

I'm just trying to get a basis for these failures..

If the rear in my V gets louder and I need to bring it to Caddy again, and this happens again with another rear! Goodbye V!:madtalkin

Speed was through 35-75 mph
Noticed around 10K let it simmer until it fried at 20K (changed by GM)
StealthV Cags, StealthV CAIK...no burnouts....I did notice wheel hop on hard 1-2 shifts with the F1s.

FWIW

SBONES,

I only get the whine upon acceleration between 60-80 when the car is warm. after 20 minutes of driving. On the original rear it started the same way, as it got worse it would whine earlier and earlier, 40-45mph, then 35 mph then all the time!

Bowen, do you have the pinion support from BMR?

Mine started around 8k, was ~11k before I got the dealer to hear it, and it was replaced. Now 20k the whine is back but not at full song, it's noticable tho. No braces, supports or other driveline mods.

Mine started at ONLY 1,000 miles and was easily noticeable over the radio when they replaced it at 1,700 miles. It squeeled like a _____ from 30-50mph in any gear 4th and above.

I did the Cadillac recommended break-in on the new one, changed the fluid with redline and have around 1,400 miles on the new one. It has been silent.
