What are all the typical leak points of a WD45 where any oil would leak out of? I know I need a PTO seal set, o-rings for the remotes but I can't think of anything else. My mind just goes blank when I get to this subject for some reason.

The seal on the axle shafts out by the final drives. We had to have the shafts welded and machined to get rid of the rust pitting on the shafts where the seal rides. We got 5 minutes out of the seals otherwise! Welding and machining was about $10/axle more than a speedy-sleeve. While you'd have it apart, check the other end as well.

Loose bolts between the front of the trans hsg to the torque hsg, sometimes requiring a split to replace the gasket if damaged too badly. Also the rear cover gasket when the PTO has been removed and the 1/2" left out of place. Finally, there is a tin cover on the bottom of the tranny housing that has a gasket also.

Thanks, I'll have to go out and look at it more tomorrow. 11:00 PM here and I've got school.
