My WD has gear oil leaking from around the outer final drive area. It runs down the inside of the rim and makes a horrible mess. Do I need to pull the final drive to get the parts out to fix this? Just curious how big of a job I am about to get into. Thanks.

Glockhead - Not tooo big a job.  Need to remove  dust cap, and bull gear pan.  The operation is like replacing wheel bearing.  Remove capscrew, washer and shims.  Remove snap ring and support the bull gear.  Push out wheel axleshaft.  This allows access to the seal.  Suggest you check the bearings also before reassy.  -  AL

Hey Jessy, The hardest part of doing it is just getting started. LOL
Block it up good!
When you pull the pan off there will be the nastiest mess of hard grease you have seen before. Have fun and be careful (>:

Yeah, I have calcium filled tires and am dreading wrestling it off. Once it dries out here a little more I need to fix this. I hope I do not find any bad hard parts. I think the bearing is shot but I hope all else is OK.
 
Still need an overhaul kit for the engine too. Too many projects, not enough time...

I did this on my WD a few years back and now I've got to fix my WD-45 as well.
I found that the seal surface on the axle shaft was pitted quite badly. I cleaned it off with brake cleaner and removed all the rust with a wire brush on an air die grinder.  Then I sprayed it with brake cleaner again and blew it off with compressed air. I then applied liquid steel, filling all the pits using a plastic bodyman's spatula. I sanded it smooth finishing with 400 grit. Put a new seal in it and has never leaked since. Of course the easy and quick fix is to install a redi-sleeve and matching seal assuming one can be found that size.

One thing that I like to do, It just takes a little more time is to spin the wheel all the way out, Then you can hit the wheel center to get the wheel off the axle, I leave one bolt in the hub(back it out some) so the wheel will not fall to the ground.

Brian, I assume that this thing is going to be rusty. It's old and seemed to be neglected before I got ahold of it.
 
Norm, I already have all the machine work done. I just need to call ya and get a kit ordered and put it back together.
 
Don, thats how I did my CA last year when I fixed the hand clutch. Worked good and kept the tire from getting away from me.
