My axle seal is leaking on the passenger side. I looked at the service manual and noticed a special tool is needed to remove the seal and push the new one in. Any way around this or just your experience? This would be the first time I have replaced a rear axle seal.

yeah,take your time, and between a chesel and an old screw driver you can get the old seal out. and I used a wooden dowel and tapped the new seal in.

A couple tips: Be sure not to install too far, or else the seal will not ride on the machined surface of the axle. Not far enough, and the seal may contact the bearing collar. Measure first! Also be sure to check axle end-play while your at it... some good info/diagrams in the service manual as well.

X2. Never used anything that wasn't already in the tool box or lying on the work bench...

Also, support the axle as best you can while you insert it into the housing, so as not to contact/damage the seal lip as it slides in....

The axle seals are always fun to replace, I had to replace one on my passenger side as well several years ago. Make sure you have a good jack to remove the differentual, those babies are heavy. Once it removed and you remove the lock ring the axle will slide out. I did not use any special tools to remove the seal other than a screw driver. A good hint would be to take some pictures of the old seal before removing it so you can remind yourself which direction to install the new one. Ensure you also take a couple of measurement so that you press the new seal to far into the housing.

??? You do not remove the differential to extract an axle from an 8 3/4 rear. Maybe confusing it with another type?

i smear a thin coat of grease on the seal too. A dry seal will fail prematurely. :cents:

You can use a piece of PVC pipe 2.5" with a cap to drive in the seal....

You guys are good, I am mistaking. When I replaced my rear seals I also change my Dif at the same time. I change the 3:23 out for 3:55. I had waited to do both jobs at the same time. It was many years ago around 1990.

Getting them out is easy once you pull the axle. The passenger side has the adjuster on it so you have to adjust the end play of the axles, or just go to a green bearing and take out the thrust spacer between the two axles. Make sure whatever you use to put that seal in is as close to the circumference of the seal as possible. Some use large sockets, and others pipe, but if it doesn't go in square the side will buckle or jam, or go concave in the middle. I found a piece of pipe that was perfect and cut it square and worked like a dream. Take your time and seat it square and do not beat to death.
If you are interested I have two original 69 axles with green bearings on them for a good price and they only have about 5 miles on them before I decided to narrow the dif and put in moser axles. If anyone is interested PM me.

Billy - start a new thread in the for sale section - that way they won't get missed by a prospective buyer.
