    Need to change brake pads (got a crack in one pad) on 1987 ltl 9000 Rockwell drive axles with cast 5 spoke hubs. What's the procedure for this and any tips for doing it or things to check. Any tips would be appreciated.

    The main thing is the whole nine yards has to come off. Pull the axles, remove the wheel bearings, and slide the whole wheel assembly off. If you have a wheel carrier, that is easy. If not, lay down something like sheet metal and oil it up. Lift the axle so that the metal will just barely slide under the tires, remove the bearings, then slide the complete assembly off over the sheet metal. There is no need to remove the tires and wheels from the hub.

    The easiest way to remove the axle is to loosen the nuts, bang the center of the axle with a BIG hammer, and the keepers should jump loose.

    So I have to pull the axle out of the rear-end housing ?? Or do you mean I pull the cover off the end. I assumed after I popped that axle cover off center of the hub then then i'd have to unbolt hub from axle then pull hub bearings out then slide hub and drum off ?? Never done one of these thought I'd have to pull wheels off too nice that I don't have to do that. Are there seals to watch out for or that I should just replace while I got it apart and what works better the sheet metal or I have a small forklift I could use like a wheel dolly.

    That "cover" is the flange at the end of the axle. It's part of the axle.

    Everyone has their own way of doing things. I find it to much easier (if you dont have a wheel jack) to pull the tires off. To pull the axle you loosen the 10 nuts in the center or the hub, take a big hammer (4lbs hammer will do) hit the center of the axle and it will bounce the keepers out. Pull the axle out and you will see a large nut, There will be some locks bent down over the nut, just run your fingers around it and you will feel them. I use a dull chisel to tap the locks up away from the nut. Unscrew the first nut and remove the lock then unscrew the other nut. Wiggle the whole hub and that will make the outside bearing push out. Make sure you back the brake off and have someone to help you slide the hub off. It'll be somewhat heavy being the brake drum is mounted to the hub. Replace the wheel seal. The old one won't be any good once you remove the hub. There should be a part # stamped on the backside of the seal. Since you've never had it torn down before I'd go ahead and clean the bearings real good and check those for flaking and the racers in the hub or it wouldn't hurt to go on and change the bearings and racers too while you have it apart. They really don't cost much and you'll know what you have when you put it back together.

I stay this cause you didn't appear understand some basic terms used in one the above posts.

    Look Ive rebuilt harley's from boxes of parts,repair my own vehicles,rebuilt engines,worked as a mechanic at several atv and motorcycle shops (and am certified mechanic on bikes and atvs,watercraft,small engines)and 2 farm tractor shops I can do this just didn't know how it was put together and no manual to look at or I probably wouldn't have to ask. Thanks for the concern and if I wasn't sure of my mechanical ability I wouldn't last thing I want is to kill or hurt someone by screwing it up. It's just the first time and I like to have my sh** straight before I jump in plus tips on getting it done easier always a bonus. I'm just use to reg cars/trucks that you unbolt hub from axle. I didn't realize that that cap was the end of the axle or that the hub was actually bolted to the rear-end not the axle itself. I guess I was just really wanting to know how it was put together. Thanks for all the info everyone think I got it now. What's the torque spec on axle bolts and the hub nut if anybody knows off hand.

    I honestly don"t know the torque specs. We've always tightened them down as tight as we could get them then spin the hub until it frees up some then tighten alittle more. I'm not gonna sit here and recommend you do it like that but it's how we do it. In 20 yrs I've never had a hub come off on me.

    Found a schematic I see how it goes. Bill 104 not sure what I said that you thought I couldn't handle this I just didn't know how it was put together found a print online no problem thought it was gona be a bigger pain in my *** I did the front u joints in my 06 dodge 1ton last fall what a pain. If dodge would use a nickel worth of antiseize on there wheel bearings and better ball joints/u joints everything now days non greasable from the factory. Thanks again those who replied :biggrin_25514: should be able to do the brakes no problem today after run get parts.
