Breaking in Rear End

839 Views 6 Replies 5 Participants Last post by  Mstehle
Hey guys:

is there a proper procedure for breaking in a rear end? Took the existing 12 bolt peg leg with 3.55's and had it updated to posi with 3.73 to run with 1350 yoke and U joints and a drive shaft from Denny's. Is there any procedure required to break in the rear end or do I just drive it mostly normally for 50-100 miles or so then let er rip? First real drive in the car will be about 130 miles or so.
