8.5 in rearend

That plastic retainer junk is exactly why A.I.R. pumps aren't always easy to replace bearings. Also the unobtanium plastic fan breaks 90% of the time. The front bearing has that plastic channel filled with plastic stuff to retain the bearing, which happens to be the same as the alternator front bearing, which has a retainer. No front retainer plate for the A.I.R. pump.

I've done it that way most of the time, for people who don't have much experience with them the smoke wrench is the easier method.

I got the slip yoke off yesterday using torch, vise, socket, hammer. It seems there's some fiberglass packing in the groove with the plastic that is injected.

After I destroyed that pinion, I will be buying the 12 ton press from Harbor Freight and I will stop with this Mickey Mouse hammering sh*t.

Could be the plastic crystallized from the heat. A press is nice to have.

That's probably expired yesterday on the 15th.. sometimes that's my luck too.

Here's a new ring and pinion. First assembling shows five to seven thou backlash, and a pattern that I think looks high on the tooth. This is with 42 thou pinion spacer.

Couldn't wait.

Also put in 0.590" solid spacer (0.042 shim), and tightened pinion nut to about 80 ft lb, yielding about 10 inlb of torque on very lubricated bearings. I didn't have the leverage to get 200 foot pounds yet.

I'm going to increase the pinion spacer from 42 to something more...

I'm following this one and learning a bit from it as I've never messed around inside a differential before.

The aftermarket pinions have a press fit with the outer bearing. The factory pinion has significantly less interference. I've used a hone with a bit of sanding ribbon to make an outer setup bearing too, so I can get it apart as I shim pinion forward and aft and compare mesh pattern. I replaced that outer race (saw some pitting from the banging), and got a new outer bearing for like $15.

The last time I had to get factory installed bearing cups out of a drive shaft, I took it out to the HD dealership and they took a big red wrench to the ears in which the cups were pressed until that plastic resin literally "boiled" out of those small holes in the loops. After that there was no resistance to getting them to move with a large hammer and a socket. A bit of machine cloth cleaned up the inner surfaces of the loops and the new cups went in just fine. Only thing to watch for is starting them absolutely straight in the loops. Get them cockeyed and they will jam, making getting them back out a nuisance.
