Saturday night after doing some pretty soft core four wheeling I stoped for gas. While it was filling up I took a look around and under the truck just to make sure everything was ok before the drive home... Well to my horror the rear 10 bolt seemed to be leaking where the Pinion seals to the axle. Looking closer I saw where the two meet there was a bunch of long grass wrapped up inside between the meeting point. So I pulled out most of the grass with some dificulty and drove a few miles, stopped, and repeated the process. I did this about 4 times and on the last stop there wasn't any more grass visible but there was a small leak at the meeting point. Now I've read on here and on the internet and it sounds me me like the pinion nut may of come loose and/or the seal got muffed up becasue of all that grass getting in there. I guess I'll pull the shaft and take off the pinion nut and replace the seal this weekend and replace the gear oil as well... but is there anything else I need to do? Some places I've read talk about replacing the crush sleeve(I think, may of been something else)... do I need to do that also? And the only thing I can't seem to find is what to torque the pinion nut back down to after I'm done. Thanks for the help.
