Planning on purchasing a differential housing for my 04 LLY. I think the seal is starting to go and with the long harsh winter I figured why not go for added capacity. looking at the Hytec and ATS unless anyone can recommend otherwise.

I was also hoping on getting advice on cleaning once drained and removed. I will obviously visually inspect the rings pinion etc etc once removed but is there any think I shoudl not use to clean it out or should use. I mean I am pretty clueless onb this so things like water I would think are a huge NO but I honestly dont know.

thanks in advance
