I finally have everything back together.
The hour in-car job took about 10 hours not counting days waiting for parts or participating in my real job.

This is the link to where it all started.

I was getting a bit concerned because Memorial Day is coming and I'm traveling to China again for two weeks. We have to participate in the town's parade ! :-)

Since the rear had a gasket in it I put one back in and the new thrust bearings were within .005 of the old ones but I was concerned that the clearances were off.

I backed it out of the garage - it went backwards OK - yea! -- and did a quick pass thru the neighborhood - another Yea!
There were no extra noises or humming from the rear so I guess the clearances are OK. - Cheers from the mice and numerous spiders that watched me get my shirt dirty. :-)

I can say that although it was a pain to do I can now sleep better knowing that the thrust bearing problem will not sneak up on me..

Fred,

I'm impressed that you did it under the car. I probably would have gone four more bolts and pulled the whole thing.

Did you use bronze washers or the roller bearings?

Steve

I didn't know what I was getting into.
There was a position that claimed it could be done in an hour under the car - I figured it would take me 4 but was wrong

I have done it in an hour. But I knew the pinion bearing was good. I had the new bronze washers. And had done it before, not in the car. It also helped that the wheel hubs weren't stuck.
Someday, someone needs to bring a T by my place and time me. David D?
Drive carefully, and enjoy, W2

I didn't have any of the problems you mentioned..
Wheels came off easily.
I had the bronze washers.

It took me an hour to jack up the car, remove the wheels, undo the left side radius rods, the E brake rod, the bolts around the pumpkin, and the three bolts on the left side of the pinion bearing support.

Then it took me over an hour to learn that I needed to loosen the other three Pinion bearing bolts before the left axle housing could be removed.

After that is was almost easy except for a "time out" to get new pins that stop the steel washer from rotating and a gasket from Langs.

I suggest that when you have the axles out you remove the inner seals on both sides because it makes it easier to put things back together.

Reassembly took about two hours - including new cotterpins, filling the rear with new 600W oil, and putting the tools away.

Good job Fred! I rebuilt my rear axel this past winter and I'm glad I did. The only decent looking parts in it were the original babbitt washers, which surprised me. Did you check the pinion sleeve, mine was cracked and ready to explode. James B

Jim -

I did a quick look at most of the insides and was surprised to find very little indications of wear.

I figured out where the outer thrust washer rode when the pins broke off.
There was a bit of wear on the edge of the end plate of the left inside bearing.
(I think the pieces of babbitt helped take them out.)

I did not look at the pinion bearing sleeve but the pinion had no slop and there was even contact between the pinion and ring gear.

If I were to do it again I'd remove the whole assembly from the car.
It has to be easier than laying on the floor and messing with a bunch of greasy bolts.
The only downside would be finding a place to put the jack stands that did not interfere with the radius rods.
