A little hlp with hubs.
- I really want to change the hubs out on my 82 GSL, I've seen this sone on cars like the 240SX where you just remove the axel nut. Is it hte same on the RX-7? A buudy of mine said you need to have a machine shop pull out the hubs. I don't know what to believe. I've tried the search but found only topics about switching the GSL-SE suspension in. Any help would be appreciated. Thanks in advance.

Front Brakes:
Take off the Caliper, then the caliper mounting bracket. The mounting bracket is a royal bitch. Once you get those off you take off:
Grease Cap
Cotter pin and lockwasher
Bolt
Keyed Washer
Outer Bearing
then pull the hub/rotor assembly off and remove the inner bearing
When you install your new hub/rotor assembly you'll want to install the races for the bearings. A good way to do this evenly is to use the races you punched out of the old rotors and a rubber mallet to evenly drive the new races into their grooves. Then grease and install the inner bearing, and install the grease seal.
Slide the rotor onto the spindle and make sure it seats properly. Then grease and install the outer bearing, keyed washer, bolt, lockwasher, cotter pin and grease cap.
Congratulations, you've swapped the front rotors/hubs/bearings.
As I mentioned earlier, the bottom bolt of the caliper mounting bracket is a bitch. A 14mm stubby wrench is needed, and the stock tire iron's flat end is very useful for pushing the wrench on. Use the box end of the wrench and lots of PB Blaster or "Liquid Wrench" to break the nut loose, then pull the wrench loose and use the open end (or you'll get the wrench stuck in there and not be able to get the bolt far enough out).
For the rear hub/bearings it's much tougher. You need an axel puller and the bearings IIRC are in the diff itself. They're pressed in, so it's not a Do-It-Yourself job.

Well I'm not sure what you're trying to do.
If you're trying to get a GSL-SE's bolt pattern on your '82GSL, then you'll have to swap out the front spindles entirely (because the GSL-SE rotors only fit the '84-85 spindles) and the rear end should be swapped as one piece too because it's a PITA to get the axels out. Besides, the -SE has a better Diff and different gear ratio IIRC.
Adapters can be found/made for 4x110mm to 4x4.5", but you have to roll the fender lips because they push the tires out almost an inch I believe.
In either case, you're gonna have to end up replacing all the brake components anyway. That's what's stopping me from doing the swap. I just put hundreds of bucks into replacing all my brakes and don't want to have to do it again, *just* to have to buy rims with it too.
It sucks, but those are the probs. At least for my fronts I could just buy a set of GSL-SE discs and bearings and I'd be set ('cause I've got an '84GS and the spindles are the same size). The rear would be a different story (I've got drums).
