Thanks for the firsthand info! I really appreciate it. I got a quote from him, and it was so low that it made me nervous actually.I have used SFF Customs for a regear and axle swap. He has also helped me with a few other projects. His name is Josh and he does solid work for a very reasonable price. It is true that he will reuse any part he can, unless told otherwise, though he does inspect everything and makes recommendations based on wear. I am very happy with his work. His site advertises a regear for 800. Price goes up if you want specific branding on the gears.
So what should I ask for to make sure everything gets done right? What brand of gears is best? Should I ask for Timken bearings? How about LubeLocker reusable differential gaskets? I put them on my XJ when I put on my Solid diff covers. Unfortunately I had a shop work on the front end after that, and they ruined my inner axle seals and then threw away the reusable gasket when they fixed them. Needless to say I don't go there anymore.
