How many seals do I need for a passenger rear axle

[Bobby198412]

I'm replacing the axle and it see I need an inner and an outer seal. Also how many bearings do I need? 2? Thank you

When viewed from the axle wheel end the axle has an inner seal behind a single outer bearing. Then there is an outer seal that is pressed into the brake backing plate. So 1 bearing and 2 seals per outboard side. The inboard axle bearing, the diff has to be pulled to access.

#1 and 2 bearing cone & cup. 

#3 seal.  Outer seal not shown is pressed in to brake backing plate.

So do I need to remove the bolts on the rear differential? How does the axle shaft come out of the rear diff? I read the manual and I'm not getting it. I'm newbie to this.

No, the rear differential stays as is. The order of events goes like this:

 

Jack up car.

Remove Wheel

Remove Axle nut

Remove drum using drum puller

Remove axle shaft key way

Remove brake assy 

Disconnect Wheel Cylinder brake line.

Remove brake backing plate nuts

Remove backing plate.

Place drum on axle shaft without key way in place. Thread axle nut on a few turns. Use drum hub as a dead blow-hammer to pull out axle and bearing assy.

Place axle assambly on the ground.

Use 2 finger attachment on slide hammer and pull out inner axle seal.

 

There is nothing keeping the axle in the diff. It will slide out with a little effort. It does not have to be lined up a certain way when re-installed. Just slide it back in.

Seal installer or some other type of tool will be needed to install seals. Perhaps a proper sized socket will work.
