Leaking from rear end. What is broken? I have a picture
After wheeling in deep mud and rocks I noticed some oil on the floor of my garage. I checked the level in the rear diff and as soon as I pulled the plastic plug thick oil started to ooze out. Is the level of the read diff supposed to be over the plug on the rear of the pumpkin?
Anyways, Here is a pic and you can clearly see where the oil is leaking from.
There are several techniques I've read about. One is doing it the fsm way measuring the pre-load to determine how much you need to torque the pinion nut to. The other involves something like marking the current location of the pinion nut and then just tightening it back to that location after replacing the seal. I don't remember the details. In a few older threads I found before, Jerry B describes how he did it for his TJ D30 or D35 (I can't remember) which both have crush sleeves without measuring the pre-load. I had a D30 pinion seal leak about two years ago. I was going to replace it myself, but went ahead and got it replaced by a shop for 50 bucks and 30 minutes of my time for the peace of mind.
One last question. I found it odd that I was still leaking fluid the following day (about a 1 foot by 1 1/2 foot puddle). I removed the rear drain plug and it starting to ooze oil. I then put the plug back in to stop the loss of diff fluid. I'm guessing that it was overfilled to begin with above the level of the pinion seal and thats where the puddle came from.
Should I be worried about driving it to the shop tomorrow?
Will the level of fluid be ok to make a 10 mile ride?
