Front differential 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.
Same noise 2007 Cadillac EXT around 74,000 miles!
front diff noise- vibration
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.
Front wheel bearing assembly went on one side a year ago and just recently on the other side.
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!
Has 44,000 original miles and is making a grinding noise. Pretty sad when gm don't fix their mistake.
Front differential needed rebuild, same as other commenters. $2600.
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.
86,000 original miles. Front differential disintegrating. Cost to repair, $3,150.00.
