Hi all,

I am having a problem removing a stub axle to do rear wheel bearings on a 95 993. I have done this several times before without incident.

I have a 3 jaw puller on the wheel flange and the axle, the axle pushed out, but the dang stub axle will not come out of the hub.

I raised the hub so the axle was mainly level as suggested by Bob.

I have destroyed the threads on my cheapo 6" 3 jaw puller. Seems like I was putting 80 ft lbs into the wrench on the puller which is much more than I remember on the others.

Any ideas? Get a bigger puller? Get a better puller? Get a sledge hammer?

What about trying to remove the bearing retainer plates... Perhaps I can get the whole thing to slide out?

Any advice appreciated.
Thanks.
Pete

Hi Pete,

My car is currently up on stands for the same operation... the rear wheel bearing on the Right side was shot! The hub and race came out frighteningly easy, but the other side was reluctant enough to compel me to borrow a friends BIG 3-arm puller. Came right out with that...

Thanks again for the bar measurement!

Cheers, Mark.

My pleasure. I guess I need a bigger puller then... Off to the store.

Bigger and better puller - those Harbor Freight types are made from butter steel -- about the stiffness of butter.

Once you have the hub loaded up with the puller, try some tapping with a soft hammer on the hub. Sometimes these will pop loose with some tapping and preload.

What gave it away?

Found a hub puller. Finally came off, requiring waay more force than I expected.

Thanks.

Hi Andreas,

Subtle clunking noise and feel from the Right side prompted me to pull the brake pads out and feel the bearing while rotating the hub... and it just wasn't the smooth silky sensation the other side presented. It's a little hard to really feel the bearing as the drive shafts add some sensation, but comparing the two sides convinced me of the problem. Sure enough, when pulled apart the grease was dried up and nasty looking and the ***** and races were starting to dis-color... it was probably ready to start making the classic chirping squeal. Good thing to keep an eye on, especially when using sticky tires on the track...

Cheers, Mark.

Another way to test is to find a flat place like a parking lot, turn the car off, and push the car fwd and back. You could hear some strange noises from the bearing, and you could also tell which side.

With the engine running I couldn't hear a thing, but with the engine off it was quite noticeable. It was much more noisy than just the brake pads dragging across the rotors.

Great idea. Never thought of that.
