Default Getting pinion bearing off

I was wondering if their is any other way to get the Pinion bearing off other then a bearing puller and a press. I have my 4:11's with the install kit and everything. this is the only thing stopping me from putting them in. I also think the carrier has the two side bearings that are pressed on. any tips on them?

If you cut the bearing retainer and remove all the bearings you can try using a 3-jaw puller. The pass side carrier bearing was hard to get at and the bearing puller broke the bearing retainer off just leaving the inner race. so I had to get it started with a 2-jaw puller which was a huge pain in the ***, but once it broke loose I could finish it up with the press. The bearings are on tight as hell so it takes some force to get them off. But if you feel comfortable you can cut them off with a cutoff wheel and chisel.

a trick to put them on is put the carrier and pinion in the freezer or a cooler with dry ice overnight and put the bearings in the oven or on a hotplate, they'll pretty much slide right on.

If nothing else pull it all off and take them to a shop, they'll be able to pull the bearings off in no time and shouldn't cost too much for a half hour labor? Small local shops might not even charge anything.

Look to the future also, how are you going to get your brand new bearing off when you need to change pinion shims during the set up? Sometimes you need to try several different shims before you find the right one.
You can get another bearing and hone the ID with a brake hone so the bearing slip fits. When you find the right shim, press the new bearing on, press it on once.

If you find the right size pipe you can put the pinion on a piece of wood and install the bearing with a hammer and the pipe. Also during set up don't use the crush sleeve, grind the crimps out of the old nut so it threads on by hand. Set the preload and test the contact pattern.
When you find all the right shims, install the pinion seal, new bearing with the right shim, crush sleeve, etc.
Hope it makes sense I'm running though it pretty quick.

Don't know if there's specific ones for these, but I think the one's I used were just from Sears. they have a small selection. You'll need a 2 jaw puller to get that driver's side carrier bearing though, I got mine at seats also.

I have and use that 'only tool you will ever need'.Expensive but works great.
I have 'slip fit' bearings and 'tapped out' pinion nuts for setting the pinion.Used crush sleeves are also 'un-crushed' to use as a temporary without having to crush a new one.

Thats a fine tool, however if you are attempting a gear swap at home and dont want to spend $500 for a puller most auto parts stors and even local shops have presses, just bring the parts there and see how much they get to remove and install bearings, should be pretty cheep
