I have my rear end apart now installing new axle bearings, seals, etc. My two questions are 1) When installing the pinion nut back on the torque setting used is not nearly important as the drag(pre-load) on the pinion bearings. I'm not rebuilding the third member as it's fine just pinion support and pinon are both leaking or one is leaking. So while it's out new seals all the way around. First step in the process is to measure the pre-load before marking the pinion and nut. I have heard anywhere between 120-180ft/lbs on the pinion nut is needed. And to go 1/16-1/8 of a turn more when installing the nut. However- staying at 15-20 in/lbs (for used bearing) of drag is more important than zipping the nut back on. As long as the yoke doesn't have any movement I'm good. 2) Is it ok to put some RTV on the splines of the pinion to help prevent leaking through the pinion splines? I could of swore I read it somewhere but can't seem to find where I saw it.
