Title: Rotor Replacement
Post by: Lt.Del on June 06, 2006, 08:43:00 pm: I know I am new to owning a 4x4. This sub is my first one. Anyhoot, I want to replace the front rotors. I thought it would be a simple thing. It still may be, not sure though.

I bought two new front rotors for this 3/4 ton 2500 series GMC.

Now, I started looking at this baby and do not know where to start.

Do I have to remove the hub?

I know I have to take the caliber off, but did not want to until I figure out the rest of it. I gotta drive this puppy tomorrow.

Any input would be fantastic.

Anyways, you have a ring clip around the spindle that comes off, be careful because the inner spring will come out in a hurry! Then you will need to pull out your 4 pin spanner socket to pull the outer locknut, then carefully pull the spacer out. Get the socket back out again and pull the inner nut, drink a beer, soil a few more rags as to not get the grease in your beer then reverse the process starting with opening another beer. Sounds simple huh???
Hope this works, your pic w/ new stuff on it>

Post by: Lt.Del on June 06, 2006, 08:52:00 pm: Sounds complicated. I was afraid of that. The dang chilton manual said for the V series trucks, i would need a special tool. Heck, i don't know if it is a R series or V series. Man, that's alot of stuff to do.

Do the lugs need to be pressed in the new rotor?

Thanks for the replies.

Post by: 1976Scottsdale on June 06, 2006, 10:13:00 pm: Either place should have them. You will need the Four Wheel Drive socket(The one with little slots, looks like a great big Impact socket with no sizing.) You will need something to drink. You will want some 707L grease(red stuff) to re-pack your hubs and bearings. Might also want a spindle socket, not sure about that one though, it uses a slide hammer to remove the spindle.

Come on Guys, doesn't somebody live close enough to Sarge for a Wrenchin' Party?

You need a 4 prong Dana 44 socket to remove the hub.

An dby the way you will have to press in new studs but you shouldn't have too much of a problem w/ that if you have a good enough thumper, BFH, hammer, whatever you want to call it

Post by: Lt.Del on June 08, 2006, 10:16:00 pm: Well, i greatly appreciate all of the insightful information. It doesn't seem tooooo bad. I think that advance gave me the wrongn rotors though. The new ones just aren't as deep as the ones on her now, maybe 1/2 narrower b/w the brake surface and lug nut stud surface.

Not too sure about pressing the lug nuts back into the new rotor, if I can get the old ones out.

I may be putting this job off a little. There is just the smallest of vibrations when braking at high speeds.

Thanks again.

Andy
