I want to replace the axle seals on the automatic transmission before I put it back in the car.
The passenger side looks like it will be a fairly straight forward removal, but the driver's side looks like it may be more difficult.

Any recommended ways for pulling it out?

Thanks for the help.

both sides go basicly the same way:
loosen axle nut first before jacking
remove wheel
undo ball joint
optional for more swing - undo tie rod
seperate axle from knuckle
put drain pan under trans
pop out axle

Axle seal leaks is often a sign that axle bearings inside need work. Axle bearing is a Sleeve type.

It's a used auto. trans. that I am using to swap out for a bad one, and I just figured it would be a good time to change these seals before I put the engine/trans back up in the car.
The axles are already removed. It's an '88 GT, so I pulled them off before I dropped the cradle.
I bought a seal puller tool at Northern Tools, but the driver's side has the end of the output shaft sticking through the seal area, so it may be a bit hard to get that tool in to pull it out.

Yes D side is a pain.
Careful whatever doesn't damage the trans.

OE Seal have metal shield... Remove Shield can help removing the seal.

The seal puller from Northern Tool, a Grip brand name, turned out to be a POS, that bent the hook easily when using it the first time. Most be China cheap.
I ended up just bending the steel part of the seal with a large screw driver, as I have done on the past with a Getrag, and popping it out.

I'm going to bring the POS Grip brand seal puller back to Northern for a refund. No customer satisfaction with that unit.

I have done that in the past to just about any type of seal that has the steel around it, if there is enough room just clamp a small pair of vise grips on the outer ring, once you get it pried out a little and use the vise grip as a lever, works every time.
