rear wheel bearing extractor

fmarin · 11-20-2005, 08:46 AM

Does anyone in the Denver area own a set of specialized tools for extracting the rear wheel bearings on a 1973 - 911T? I would gladly offer a case of beer, wine, or whatever, to be able to borrow these tools. Thanks. Fred

If you can't find one to borrow, this assortment of parts will do the job:

Wow,

That's great. I think there's a trip to the hardware store in my future. Thanks for the parts list.

I understand some colorful language may also help.

I'bve got a thread somewhere with these parts and the how to. Buy an extra piece of threaded rod as the threads can get messed up. It's fairly straight forward, but can be a real grunting afair.

i used (and still have) johns diy tools for the rear bearings, make sure everything seats right when you start to hammer/crank away, if it is not centered and distributing even force it get's REAL frustrating

also put your bearing in the freezer (mine was in for 24hrs) and don't remove it until you're absolutly ready to install it.
the biggest "headache" i had was removing the outer bearing race from the spindle, luckily christian (a quiet boom) saved the day with his industial press after i called for reinforcements, i imagine it could be cut off worse case scenario.
good luck

I had a tough time with the above homebrew tool. One the left side, it worked pretty well. On the right side, I found the limits of those floor plates. In fact, I even doubled them up and still crushed them. In the end, I took the bearing innards out and cut/chipped the outer race away. By carefully dremmeling some slats in the race, I was able to break a wedge out of it. Crazy, but it worked.

Next time? I'm buying the tool.

Hi guys, recently been through this so thought I would pass on what I learnt.

I built an extractor with bits and bobs I found & bought - cost about £10:

I used the wheel off my jack and the front inner race of the bearing I was removing to pull against the outer race of the the bearing from the inside, this then went through the hub then through a big tube(gaffer tape the end to prevent damage to hub) and then through the leg of my axle stand then a few washers and nuts and off you go:

It all hooked up nicely but wouldnt seem to budge the bearing before something else looked like it would give so I heated the hub with a paint stripper gun for about 5 mins then it just seemed to slide right out without much force at all. The heat was deffo the bit that got it going.

I also used the gun to pre-heat the hub before I instealled the new bearing that had been in the freezer for 3 days - slid right in to the end no probs.

good luck!

Yes, use heat. Amazing stuff. I did much banging and swearing and nearly cried before resorting to what others had said, Use Heat! I just used a propane torch and instead of banging and swearing, I just lay under the car for a few minutes and it came right off. I, too used a homegrown concoction of washers, bolt, large socket, etc. But the heat was what allowed it all to work. Good luck!

Definetly use heat and only heat the alum. Also a little grease on all mating surfaces and threads on the puller help. Good Luck, it's easy and simple with the help from here.

Sorry, I was in a bit of a rush with the first post. Excellent advice above - get some extra T-rod and nuts, you will bugger them up. Careful centering and alignment of the new bearing is required when reassembling. And heat is your friend - I cranked some torque on first, then heated all around the bearing until I heard a "pop", then they cranked right out. Freezing the new ones (transfer them in a small cooler with ice) and heating the arm before reassembly really helps too.

I am having a whale of a time trying to get the rear wheel hub off to change the bearing on my 76 911s. I have been trying to drive it out with a socket from the inside and nothing is moving. Any suggestions about how to make this job easier. I did the right side about 10 years ago and don't remember it being this frustrating. Thanks
