[QUOTE="user 65037, post: 991392, member: 65037"] I had the same issue on my rear end of my 04. With the 4.10 and LS, I took it to local shop where they said I need the whole setup. I didn't believe them cause I wasn't that hard on my truck then. So went to another shop, they took it around the corner and said I probably just need the LS additive. Replaced the oil and added the additive and presto all better. 2nd thing, I got a quote for 4.88s and the shop quoted me 2k with yukon gears and new everything. That's both axles. so the $2500 seems quite steep unless you really messed something up, and if it was that screwed up you probably couldn't drive it, imo. The 3.73 gears are great if you don't really plan on off roading and stay on pavement 95% of the time. But you will also have to do the front ring and pinion. Best bet is get a used 4.10 ring and pinion out of a 8.8 of CL, bunch of people do that when they upgrade. Then you can keep your LS if you have one. [/QUOTE]
