Have a 02 Cadillac Escalade with a whinning in the front end. when you hit on the gas and its pulling no whining but running normal its whinning noise.
Noise detected while Escalade EXT was under warranty within 6 months of purchase. Local dealer inspected and concluded "...within Cadillac standards...". Five years later (@ ~75,000 miles), during routine inspection, same dealer noted noise from front differential. Is being repaired by Independent shop after dealer refused to adjust the repair price since original evidence (in their computer files) was so old.

Independent repair shop diagnosed pinion and carrier bearings worn. Replacing.
front diff noise- vibration
same problem
Front wheel bearing assembly went on one side a year ago and just recently on the other side.
2014 Cadillac Escalde Platinum Roaring, howling, wobbling noise coming from front diff. Has been to dealership 3 times 1st time where carrier bearings and seals replaced. 2nd time was told all AWD make this noise, 3rd time different deslership told me unsafe to drive, front diff was leaking fluid, replaced bearings again, one was missing from 1st replacement I was told, and replace drive shaft/bar. One week later, noise is back, cluncking when coming to stop at stop lights. Going to try and take it in again to see what is causing the problems.
Have whinning and gear noise coming form rearend. My differential was service by dealer and fluid changed. Now they said my rearend has metal debris and contaminated fluid. Bearings are worn and nosie travels up to front area because I have all wheel drive. I thought it was transfer case problem.

Rearend on these things do not last and suck!
I noticed that my truck started to develop a noise mainly at the front wheels. I noticed as I increase the acceleration the noise increase as well. Recently I fixed the front and rear brakes and I thought that was part of the problem. Took it back to the shop and they told me it was the differential. Now I drive it and feel like the front wheel drive is disconnected, like if the only wheels that works would be the rear ones. I probably have to fix it ASAP.

Looking for low mileage rear diff

Noise only and it has not yet been repaired
Been having a howling sound coming from the rear of the vehicle. Sounded like it had big off road tires. While driving when transmission shifted into 3rd it didn't go anywhere. Stopped and started again and it drove fine. Any ideas as to the sound and the transmission shifting problem and are they related?
