    I've been hearing some noises every now and then from the front end of my 88 3/4 ton suburban. I pulled off the rims today and the front hub section can move up and down quite a bit and it isn't the ball joints as I checked for movement in them and it seems like it's almost coming from somewhere behind that 4x4 cap. When I bought the truck in california last june I had it checked out by a shop and they said they had to repack that same wheel bearing since it had extra play. My chilton manual doesn't have any pictures to show me how to actually tighten that up, replace the bearings, etc. Can anyone point me in the right direction on how to do this. I'd actually like to swap to warn hubs from the automatic factory ones at the same time if I'm removing the same parts at the same time. Any help would be greatly appreciated.

    you need a special sockit to remove the sloted nut, or a hammer and a small drift to tap the nut around. after you put the auto locking hub

    go buy a chilton manual, it will show a breakdown to help you get it apart. alot easier than deciphering someone writing how to do it.

    Agreed. And it will have all the necessary torque specs, too.

    i have a chilton manual for 73-87 trucks and it doesn't have any breakdowns or pictures in it for this. I even checked out a haynes manual at the store hoping it might be in there instead, but no luck

    '87 pickups are the same as '88 Burbs. The info should be in there.

    Check in the Brakes section, Suspension section and Axle section. It could be in any of them.

    will any brand work or do you all recommend a certain place? I know to avoid chinese parts compared to made in USA, but a lot of stores only carry one brand.

    Timken is usually a safe bet. Autozone carries them.

    one of the bearings comes with the race the other does not. Thats why there is not a seperate listing. It doesn't make any sense why they do that. Everyone I have bought is like that.

    what he said and the spindle lock nuts are non-wear items, get a new hub seal while your at it.

    ok got the warn hubs today and they sold me some spindle nut conversion kit or something, has a few washer with tab looking pieces, did I even need this kit for any reason? I got the warn premium hubs if that matters or not. The kit talks about dana 30s, 44s, but no mention of the 10 bolt like my 88 3/4 ton burb has.

    10-bolt is the same as D44 (where hubs are concerned).

    it says the kit is needed if i have a 3 hole hub, what exactly is that? It states "if you're auto hubs are 3 hole then get conversion kit...XXXX" which I bought that was another $60 on top of the $90 for the premium hubs. Oh and thanks for the help on all this goldwing I appreciate it.

    No sweat. That's what we're here for. :D

    No idea what a 3-hole hub is. All I can think of is the drive flanges for the NP203 system that would require an additional part-time kit for the transfer case. Ditto for the "spindle nut conversion kit". Those were only on older vehicles, though. On an '88, you shouldn't need any parts other than the hub kits.
