Well I was trying to regear my differentials today, decide okay il try and pull the bearings. I try and try, than snap, I break the out shell to the bearing now all that is left is the pressed on part. I was trying to use a 3 prong puller.

I got all carriers out, pinions. Now all I need is some help to get the stupid bearings off which just won't come.

There is a sweet special bearing puller that can be used to pull carrier bearings.

(I don't have one either:D)

Last time I broke a bearing like you describe, I was able to drive it off with an air chisel. Worked better than I thought it would.

Great... I wish I had money for the tool and I don't think anywhere local would sell it and to be honest for the 5 times il use it il just get a shop to remove...

Me neither. That's why I suggested the air chisel option

found this on JCwhitney... was wondering how this might work for a carrier bearing and so on...

They do ok, I used a set on a dana 44 carrier .

Just be sure not to catch the cage if you are reusing the bearings (or if they are new bearings and need to disassemble to get backlash correct, ask me how I know):flipoff2:

Found a air hammer on canadian tire, do you think this will remove a bearing:
Features
1-5/8" stroke; 5,000 bpm
Cuts, chips, and scrapes most materials when doing light-duty automotive work
6 scfm @ 90 psi
Handle exhaust
Soft rubber grip; 2-finger trigger switch
Lightweight composite housing
Heat-treated steel components for increased durability
Screened inlet
Includes 2 chisels
3-year limited repair warranty

Thanks

That tool that is in the tech is similar to the jc whitney one. I have a three jaw that you can also turn into to a two jaw which is what you need. I found that it is still a PITA. What I had to do was get everything how I wanted it and snug the puller tight and the bolts on the jaws. Then I put a C-Clamp on the outside of the jaws to hold them together so they didn't slip and rip the cage. The big clamp puller usually will destroy the shims unless you are carefull.

I already have two broken bearings. And I was told to just cut them by a local place and pick up some test bearings from napa which is probably the easiest for me. But I guess Maybe the 3 puller breaks them? I will try using two if it allows me...

well I bought an air hammer, but it's still not doing the trick. The one I am stuck on is the ring side gear. How exactly did you use your air hammer to get it off?

take a cold chisel and a 4 lb hammer and break the race. the chisel will be junk, but the race will break if you hit it right. point the chisel in the same direction as the axleshaft coming out of the differential. Hold it with a pair of vise grips. Smack the bejesus out of it. Once the race breaks, it should slide off a lot easier.

I was going to suggest that he cut a deep groove almost all the way through the race with the Dremel, then hit it with the chisel. It should crack pretty easy, and save the chisel.

I usually use a torch to CAREFULLY cut a trench in the inner race, and then crack it through with a cold chisel. Use a small torch tip to minimize the chance of burning through and gouging the carrier. Be EXTRA careful if you have shims under the bearing (lack of shims = another reason to love the 14-bolt :flipoff2:).If you don't have a torch or don't trust yourself to not fawk it up, you could try a die-grinder with a cut-off wheel. Either way, your goal is to cut it thin enough in one spot to get it to crack when you wedge a chisel in the groove. Of course, you could always just take it to a machine shop if none of these solutions appeal to you. I can't imagine they'd charge you much.

If you have a torch hot enough to burn it, why not just heat up the race and it will fall off, or tap off easily if you keep it straight. If you are an ace, which it sounds like, that may be quicker, but most aren't that good, and there's too much splatter going where you don't want it.

I've never tried this, but if it works, I'd gladly sacrifice a chinese chisel to save all the trouble of any other method.

You might want to give it a whack...

I've tried and never had any luck, probably because there is just no good way of getting a clean strike at the backside of the bearing. If you can get at the backside of the bearing, it might work. I will say, they won't just fall off. As the carrier journal gets heated along with the race, it will expand too.

okay i will try that.

ive done the chisel trick many times.

works great.

a 10 ton press wouldnt get the race off of a 9" axle. I hit it 3 times with a chisel and 4lb hammer, and it broke.

Generally, though, my friends dont let me handle hammers around them..
