Hey guys, my wife and I just bought an 02 Escalade from my local Caddy dealership, and after just 2 days of ownership, my wife calls me about a clicking noise when she turns either right or left. I took the truck back to the dealership and they of course told me it was bought as is, but they were willing to help with the cost. So, after diagnosing the problem it turned out to be the front differential. Has anyone else had this problem? If so, what could I expect to pay for a new or used differential. Thanks in advance.
