Sounds like you have a good project to keep you busy.Wouldn't hurt to fill up the diffs,get it running and see how it does before you tear it down.1300 miles on a 12 year old machine tells you it wasn't ridden much. Again hurts them more to sit up than to ride them daily.I encountered a bunch of these type machines I had to fix back up.
Can the front pinion shaft seal be replaced with the Diff in the machine? Mine has the cover with the 4 bolts. I've read that you can loosen up the diff and slide it forward on some years and replace the pinion seal that way. As far as the back, excessive play where the pinion shaft goes into the rear diff, that would be bearings correct? Any tips or tricks to getting the pin out of the shaft? I gave it some good whacks with a punch and 3 pound sledge last night and it didn't budge. Do you drill them out? Should be a damn bolt in there instead
