Hey guys, new to the forum.

Just purchased an '04 F-150 Roush Stage 1. I had it for about a week and into the dealership it went.

Well, my question is, what is the breakin process or period for a rebuilt rearend? I should have it back tomorrow, I hope!

Check out Randy's ring and Pionion site. There is a write up there about breaking in. All I remember is the part about driving for about 12-15 miles and then let it sit to cool off. Then change the fluid after about 500 miles. there is plenty other info, but like I said it's all i remember.

 

Seeley,

You were right on the money!!! Thanks for the help.
