89 YJ with front axle seal leaking

I have a front axle seal on the passenger side leaking and I now have the axle out. How in the heck do you change the seal that is about 12" up in the housing. Is there a special tool for instaling a new one. I also have the shift motor off the axle for my viewing pleasure. This is another problem. I don't think that the vacumn to the shifting fork is sufficent, since I can not get the fork to move when hooked to the harness. However, it does move back and forth when I use my mouth on it.(No comments there please!) I need some help with these matters. [img]images/graemlins/crazy.gif[/img]

Yes there is a special tool. You can make one that will work. This is how I built mine.


I don't remember the measurements, but the seal disk (black) is slightly smaller than the OD of the seal and has a hole in the center for the all thread to pass through. The Plate (orange) is approx 3" wide and 10" long with a hole drilled in the center for the all thread to pass through. Cut the all thread to the length you need and weld a nut on one end (like nut #3). Run a nut (#2) down close to that nut (#3), put the plate on, slide the all thread into the axle tube into the shift motor housing, through the center of the new seal, put the seal disk on and put nut #1 on. Then tighten nut #2 while holding nut #3 to pull the seal into place. Like this.

jeeperjohn, thanks for the detailed drawing of the homemade seal installer. I am out the door to the shop to dig out some threaded rod and start making the tool. Seems simple enough to make. I would think that the main concern is to make the sizeing at the end of the seal fairly precise so as not to damage the seal.

Thanks again for the time to pass on the help!!!!!!!! [img]images/graemlins/40BEER.gif[/img]
