Leaking Rear Hub on DP
My hub started leaking recently. This will be my first experience with this. First, I am assuming that this is likely just a leaking cover plate, and not a symptom of something serious. I s...

Capstone-
I drove the coach up on some 2X6 pieces that I use for support when I work under the coach. This provided about 3-3.5 inches of lift on the offending side. I removed the bolts and washers. There is not much to grab the axle with, so I gave it a smack with a mallet, about what you would use to start a nail.
The axle moved out about i/8 inch, which allowed me to get a hook behind it. It slid out easily. It feels like it probably weighs 75 pounds.
The lube was still slowly flowing from the axle, so I built a little dam from paper towels to keep it backed up. I cleaned the sealing surfaces with acetone, and used differential RTV recommended by my local auto parts store.
The axle slid in 95 percent of the way with no interference. I remembered the orientation of the axle to the hub, turned it, gave it a wiggle and the splines mated.
I then pulled it out slightly and removed my paper towel dam. Washers and then bolts slightly tight for the RTV to set. I have not found torque specs for my particular axle, but similar ones were around 100 ft/lb.
This was an easy job, and I thank you guys for the information and encouragement. It took probably 1/2 hour, working slowly and carefully. It seems to me there are two tricks - stop the lube from running so the RTV can get a grip on the mating surfaces, and remember how to orient the axle so the holes match the studs before you make a mess of the uncured RTV.
