Wheel bearings-torque values? (90 pics)
Changed out the rears today 
Had to buy a few things to do it
-36mm impact socket, T55 torx socket
Remove cotter pin and castle nut-Your 36 mm nut comes off next, youll need a 1/2" drive breaker bar, a 1/2" to 3/4" adapter (36mm socket is 3/4" drive) a piece of pipe, or a jack handle. Oh, eat your wheaties, these things are on there pretty tight.
I removed the caliper bolts next, cant recall size (15mm)
Next come the three torx bolts from the rear of the hub assembly. May need to rotate the halfshaft a bit so you can access them all.
Reassmeble in reverse order.
What do you guys typically tighten these too? Aint no way Im buying a 300lb torque wrench. My grinding noise is gone, have to put a few miles on her tomorrow. Put the BMAD on too, did a little leak chasing and p.m. also.
Glad I tore it apart, every single one of my lug nuts were loose!

It's about 170 lbs. Set your tq wrench to 150 and muscle it a little past that. That's what I did.
Better too tight than not enough. It will be easy as pie to remove the next time around.

yup. Calipers may not have to come off, either-could leave them attached to the bracket. Didnt like the idea of letting everything hang by the brake line.
@#$, those are some ugly brakes!

I started doing this after I had a $225 AC Delco rear bearing fail after one track day and about 1000 miles total. Now I just use the cheep ones and with retorquing them before every track day, I get more life out of them.

I torque mine to 200 lbs.-ft. Loosening over time is not uncommon at the stock spec. Nuts this size will take 200 w/ no problem.

REAR Brakes
Hey guys maybe somebody here on the forum can help me. I did the same thing on my 85 and at the same time replaced the rear rotors and pads. Now my rear pads don't make contact as far down on the rotor as before. So I'm lost as to what could I have done wrong. Any help will be appreciated. TIA

When I took mine off I broke two (2) snap-on 1/2" drive 4" extensions because I had to have the tire on the ground (it just kept spinning) and in order to get the breaker bar to clear the wheel I had to use the extensions, I then went and put a 3/4" drive with 8' cheater bar in order to remove the nut, though this was only on the drivers side,
passenger side came off easier.Bob
