Extracting a wheel bearing hub?
 

This is part 2 of my original post. The grinding is definitely the bearings. George and I have taken everything off the arm including rotors, calipers, and axle.

Any recommendations on taking the bearing hub off the arm without taking the arm of the car. Some say a high quality slide hammer. Will that really take the hub off? :?

John,

A slide hammer should get the hub out of the trailing arm. I used a large disposable socket and a 5lb mini sledge to drive the hub out from the inside of the trailing arm.

Once the hub is out of the trailing arm you'll need to remove the race which should still be attached to the hub. Cut a notch in the race and split it with a chisel. Getting the remaining of the bearing out of the trailing arm will require some sort of press as you will not want to damage the soft Al. trailing arm. Installation of the bearing will also require the correct press.

I got half way into this project and decided to take the traling arms into a shop to finish it up for me.

I took them to Pitstop (with Bill) and they had the new bearings installed in to time. Cant see more than an hour labor + parts to do this, espically if you bring in the trailing arms with the hubs removed.

Charlie, thanks for the feedback. So the best way is to really remove the trailing arm and hub? Is the far bolt (by tranny) easily removed. That's the only bolt I'm worried about removing. Once I remove the hub, the inner and outer bearings (930) will come off with the hub or stay in the arm?
Do you have a slide hammer?

Charlie, after reading this: :shock: http://www.dorkiphus.com/porsche/vie...88&start=0

I will definitely use a press after I take the hub spindle and trailing arm off.

Ah, you found an old post I wish I could forget. There is some good info in there. Good idea in either buying the correct tool or paying a shop to do this for you. Others have had good luck/skill in doing this themselves, but mine obviously ran out.

Yep, doing lots of research on this topic and it's looking more and more like a press job instead of risking the expensive trailing arm.
Now, I should change the topic to how hard is it to remove the far bolt of the trailing arm. I hope I don't have to loosen any tranny bolts or mounts

Jon:

I have tackled lots of "projects" and this is one I let the shop do on my Targa. They had the "on the car" tool and the bill wasn't outrageous. Once we got in there, they discovered the hub was worn out (to many wheel bearing changes or the PO hacked it up) and I had to buy a new one. Somewhere over $300 if I remember correctly. I probably would have noticed how easily the worn out hub slid into the bearing but what if I didn't? Peace of mind for me. Front wheel bearings no problem. Front and rear on my BMW, etc... not a problem. I took a pass on this one.

Another thought: If you do want to get the "on the car" tool and it works for all 911s then maybe a Dorki group tool buy? I'd kick in some $.

My $0.02 worth.
