LF: SIR B90 tool (rent)

Looking for the rear hub/bearing tool, hopefully to rent. I know Colombian has one, but no response so far.

If you're still looking, partsource has the FWD bearing puller that worked well on my E30 rear wheel bearings and can't beat a free rental. Works well for pressing certain bushings too ;-)

I looked at that, i couldn't figure out how to make it work. I made a homemade tool to get one bearing out, but can't get the new one in. Other side is tough: hub is stuck, and my hammer technique isn't working.

It was about 5 years ago I did the rear bearings, but I don't recall having to do anything funky. I do recall that it took a lot of torque on the screw to pull the bearing/hub assembly though. It kept me warm even though it was below -15 haha

This is the type of kit you need, and what partsource has: http://www.harborfreight.com/fwd-fro...ers-66829.html

Hammer technique likely won't work - these have a good amount of press fit holding them in.

The puller will also work to press in the new hub. Just make sure you press on the appropriate race otherwise you'll simply destroy your new bearings.

Damn, I looked and couldn't find that kind of kit when i went. Any idea what they call it?

I think it's called a "fwd bearing puller kit", but not sure on the exact wording. Also not sure if all the locations have the same rental tools? I went to the one in Richmond Hill. I've borrowed the tool several times for various pulling/pressing needs

I found it, and it made the left side bearing a 5 minute job to reinstall.

Unfortunately, the right side hub is firmly stuck in the bearing, even after 5 hours of solid hammering. Any ideas?

How much torque were you putting on the puller trying to pull the RS hub? Mine took what I'd guess to be 80-100 lb-ft constant at the start to get it moving (and then it progressively got lighter as I pulled it further and further out). Based on the size of the screw in the puller, you'd probably be safe to get quite a bit more torque on there, but I'd be weary of using an impact driver. I would recommend supporting the screw while you torque it... hardened things are generally not good in bending.

Is there any damage to the circlip groove from removing the circlip that it could be hanging up on? Have you tried soaking the area between the bearing and trailing arm with penetrating oil? Have you tried a torch to heat cycle the area (this will help the penetrating fluid get in there, and also hopefully, with uneven heating, cause any bond between the two components to break).

No, i can't get a puller on there at all. The axle shaft is out, so all that's left is the bearing with the hub inside, with a hole therefore straight through. I've read that the inner bearing race sometimes gets stuck to the hub and rides it out, but I don't seem to be able to get any movement at all! I have indeed tried the penetrating oil, don't want to try the torch as the car is parked right next to a gas line (call me paranoid, but also not on fire).
I tried using a bearing separator braced against the brake backing plate, but it wasn't big enough. I'll se if I can find a bigger one tomorrow, else i'm in trouble!
