'88 rear wheel hub separation?
I'm trying to separate the rear wheel hub but noticed there is a nut (29mm?) that seems to go to the axle. I know for the hub removal I need to use a puller tool to separate it but not sure if I need to remove the axle nut first? :scratch:
Thanks

On the small pattern (5x100mm) hubs, that's a 30 mm nut. It's tightened to something like 150 ftlbs.
Put a pry-bar through the lug studs and then use a big breaker bar to break the nut loose. It's a self-locking nut, so it'll be stiff most of the way out.
You'll probably have to put the assembly on the floor and push down on the breaker bar to get enough leverage to break it loose.

Thanks... I did read that the hubs on the '88 are different then the previous years and regarding the separation here...Series8217 wrote:Do NOT use a puller to seperate the hub. It's is a sealed unit. You need to remove the 3 bolts behind the flange, and remove that large center nut you have highlighted. The entire wheel bearing unit will come off as one peice. There are no serviceable parts inside.
Is this info wrong?http://fiero.cc/fiero-tdc/members/mws/B ... index.html]
the 88 rear hubs are press-fit together!! This shows the flange portion turned upside down (on the right) with the backing flange bolted to it. The flanges can be taken apart from the hub portion, using a hydraulic press, or careful even pressure, and modified however you want. Then pressed back together after cleaning, re-packing, anything you want!!.
This is a big deal!!

That information is correct. A puller will not take them apart though. You have to use a press.Is this info wrong?http://fiero.cc/fiero-tdc/members/mws/B ... index.html]

Why are you taking them apart?
The front race is part of the flange, so you can't do anything to repair it if its damaged.
I suppose you could repack it if you don't trust the factory grease, but its pretty tough to get all the old grease out and replace it with new clean grease.
Are you changing the bolt pattern?
