I really want to thank you all for your help. But, I can't replace that rear myself. It's talking about prior to disassembly, measure and record ring and pinion backlash etc. I'm a novice and don't know where to start with that. I thought you just pull one out and bolt the new in it's place and slide your axles back in. I guess it's going to cost me big bucks for this job!! Thanks again!!
