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.
