Oh crap, you're right. I forgot about using the races. Oops

So last night I decided to shimmy the carrier over to the pass side a touch more to tighten up my backlash. Remember spec is .006-.010 and I was at .010. Took a .005 shim and moved it to the driver's side. That got me to .004. Phooey

Did some more math...

And ended up at .007!!

So then I decided to go ahead and do final assembly. Pressed on the pinion bearing. That took all the ass this little press had lol. I hate presses, they're sketchy

Put the crush sleeve on, threw the pinion in with a fresh seal and started to crush the crush sleeve. Spec here is 14-19in lbs of rotational drag. I was doing my best to just sneak up on it and kept getting 10-12in lbs time after time after time. The last push, I went just a touch more and suddenly had 20in lbs! I was so mad lol. Spun the pinion a bunch and kept remeasuring. On my coworker's split beam I borrowed, there's only 3 hashes in between the 10s, so it's kinda hard to judge anything under 20. I figured I was 18-20ish. Talked to Spencer and he pointed out that you need to add 2-3in lbs for the pinion seal. That was not mentioned anywhere in my kit or anything I read/saw online, so he's a life saver. 20 puts me right in the middle of spec

So last thing, I ran one more pattern to be sure and it came out great so I'm calling that good. Just gotta go grab some axle seals at the parts store and I can fill her up and be done with the rear

All that mathemagicianal stuff on the big chief tablet makes me infinitely glad it ain't me doing this job

With your press woes, some extreme pressure grease goes a long way on making press fits smooth, mitigates galling, etc. something like this:

Doesn’t hurt if things feel really tight to run a little Emory cloth on the journals, just enough to make sure there are no dingleberries that might give trouble.

Being a machinist, I have the luxury of being able to make sleeves to be able to press pinion bearings with the pinion facing up. I like that way as I know I’m not hitting the cage or anything, and am pressing on the inner race. Also be careful with stacking those press plates on those pieces of channel, I’d be worried about having something slip with that setup.

Nice work and good luck on the front axle!

Damn fine work sir.
All the voodoo required has me using a diff guy and paying his prices.

It's not that hard,really.It's a little intimidating,first one but really not hard. If you ever want to try,there are plenty of us on here that can get you through it without trouble.

Oooo, thanks for the tip on the lube, gonna pick some of that up. I also definitely need to get some more emory cloth, can't find mine and there were a couple small high spots on that pinion as the bearing went down. Nothing to cause an issue but made a ghost mark.

I absolutely did NOT want to stack those plates, but that was the only way I could get the spacing right. It was big time sketchy, I was watching it very closely lol. I used to work in a race shop and even then, I always hated pressing stuff. I'd use the freezer and hot plate every time if I had the time.

Thanks! This is my first time. I've always paid someone else to do them. But needing to do 2 axles at one time, I decided to spend half the labor money to get the special tools and give it a go. It's not bad, just tedious learning as I'm going. It's taken 3 times as long as it would someone that knows what they're doing, but thankfully I'm not in a hurry

Next one won't take 1/2 as long. Wish I'd known you were doing this,there are work around for most of the tools. But now you own tools,saved money and have a new skill. Even of you are an arrogant whatever that guy called.
