Thanks man - I couldn't remember what you had told me when I talked to you at the UREs. Haha, I was also able to get that caliper wedge out with a lot of PB, torch, and a BFH. I'm the one with the K5 by the way. Your buddy has a sweet YJ.
Of my 5 wheels, there is one that is a different style. It is newer version, IIRC its an '00 model. The lip that the o-ring slides into curves in towards the center of the wheel. On the other 4, it just points straight up. The newer wheel uses a smaller thickness o-ring. Just something to keep in mind.
any hummer dealer will have them, if you can't find them we usually have a set. we do alot of h1 work. just make sure if you have the older style you use the red seal and newer is orange. and don't put any grease on them.
by "those seals", i assume you mean the factory red/orange seals, i have no experience with them. i've used grease on a few sets of wheels with the Mcmaster o-rings without issues... I'd be interested to find out what the factory o-rings are composed of.
I've just seen too many of these end up swelling in the past and causing a leak on the H1's. I've never used aftermarket seals, just the factory, and they would leak if you even got alittle bit of the runflat gel on them.
