ok so i got some hubs to replace my siezed hub with but i dont know what size the nut under the dust cap is or how to remove the brake caliper so i can pull off the hub please help me i want to get my car moving again today

Your best bet is probably to pick up a Haynes or Chilton's manual. They'll have step by step instructions, frequenty with pictures and diagrams.

We need more info to offer more specific advice. Front or rear hubs? What year?

There are two bolts that hold the brake calipers on. They're large Torx bolts, but the size varies depending on year.

got a chilton but it dont have sizes and ive heard that 220ft/lbs is wrong or too much torque or somthing i do know its a t50 which i have but doesnt have the size for the hub bolt

edit: its a 1987 fiero SE V6

Get a Haynes manual. Chiltons are no good.

ok but that doesn't help me now i need to make sure im not going to hurt my car with by applying too much torque to the nut is it 220 or is it less? please help me out here

Do you mean the front hub?? Pull the cotter pin and that nut shouldn't be too tight. Even a pair of channel locks will get it off in a bind. 220 is WAAY too much to put it back on.

ok so if 220 is way too much then how much is right? and yes its the front hubs and what if i don't have a torque wrench??

I assume you're talking about a rear hub, not an 88 front hub. I replaced a rear hub a couple of months ago, but I can't remember what size any of the nuts were. Basically, I try sockets until I find the one that fits. You need to have a complete set of sockets anyway. I think the torque on the central hub nut is 190 ft-lbs. If you weigh 190 lbs and stand on the end of a one-foot breaker bar to tighten it, you'll get it just right. No torque wrench needed for this one -- just a little mathematics.

ok im sorry for being a little vague about this its an 87 fiero SE V6 front hub assembly i am trying to install and so im hearing not to use 220ft/lbs and about 190 should be fine... i have no torque wrench and i weigh 210lbs so me on a breaker bar sounds like its not an option the next lightest available person is less than 100lbs lol

No! You will crush the wheel bearings! The front hub nut is tightened until the hub starts to bind JUST A LITTLE while spinning it with your hand then backed off loose, then FINGER tight to the next slot for the cotter pin.

You are simply trying to seat the bearings by removing excess grease then removing any play with it being hand tight.

I think this is the second time in less than a year that this has come up on this forum!

If you tightened that stuff to 190 ft lb, take it all out and throw it away! Bearings, races in the hub, and the nuts.

Front hubs are not like the sealed rears! As you can imagine, bearings are not a press/interference fit, they have a couple thousands clearance, and it is up to you to give the bearings that clearance by hand tightening the castellated nut, spinning the hub a few rotations to push any extra grease out of the way of the race when setting the lash, re-hand tighten, and then back the nut off to the closest flat that allows you to put the cotter key through.

If you are having this level of difficulty with this task (even with the book in front of you!) I suggest you do this job with a friend who has some experience, as I would suspect your bearings are not adequately packed with grease either!

Good Luck!

Hey man, I might be able to help you out tomorrow. I don't know when I get off work yet, but I'll see about giving you a call. I've repacked front bearings before on other cars. You've already got all the parts right? Do you need any tools? I have a big torque wrench and other tools if you're still in need. Anyway, I'll probably need good directions since I don't know exactly where around Edmonds you are. Talk tomorrow.

Cool - love to see this kind of help being offered

I put new front bearings on mine (Just because I was doing new rotors, and the ones on the car were old) and just hand tightened the nut, while pushing in on the rotor with my other hand. The nut is lined up with the same thread it was lined up with before I took teh nut off. Was that good enough? The pin then went in on the nearest hole that lined up. I already drove it 80 miles this way.
