How much are people paying to change the differential? I have pulled out the center chunk and brought it to a shop to just replace the stock differential with a T2R and they are saying 290 just for labor not including seals and bearings. That seems very high to me. Is it really a PIA or what as I am about to go get it and do it myself for that price. I had them completely disassemble and rebuild my T-56 for less then that.
