Speaking of rear end seals,my truck is a 48 3/4 ton chevy with stock 4.56 rear end. I have a slow leak,about 4drops of oil every 24 hrs that is coming from the front of the rear end out of the differential carrier, the shop manual shows an oil seal at that position. The truck runs great,no problem, my question is after looking at that area it looks like the bolts have not been touched in 60 years, how big a job is it to replace that seal and what problems have other bolsters run into,is it better just to leave it as is and just replace the oil as needed. Thanks
