I want to replace the auto-locking hubs on my 2002 SD with Warn locking hubs (38826.) For these hubs the is a note that says; " Vehicles with 3 bolt automatic hub covers require nut conversion kit part number WAR32721." What is a "3 bolt automatic hub cover?"

 

 

You don't need the conversion kit, Warn and Milemarker are both good brands of hubs. Also unplug you hub vacuum actuator after you do that so you don't have a vacuum leak.

 

My vacuum lines for my hubs are all cracked and (I assume because of that) my auto hubs don't work. It doesn't bother me. I just lock them manually if I need 4wd. Should I unplug my actuator as well and if so, where do I find it? Thanks

 

If you have a vacuum leak your vents will go into defrost every time you put it in 4x4. The actuator is on the passenger side fender, unplug the electrical connector to it.

 

I replaced mine with Warn on a 2008 and probably the best update I've done. Well worth the money. Oh, and six screws to mount no issues.

 

Done. Thank you.

 

Dont go warn, they fdo not fit that well on the 99-04 trucks. Like already said above go G2, or Yukon manual hubs

 

I don't know if they are the same or not but going by the pictures the G2 hubs look identical to the Superwinch hubs which I would never recommend. I had Superwinch hubs and they failed in a year, I haven't seen the G2 hubs in person so I can't say much about them. I have never had a problem getting the Warn hubs to fit on a 99-04, in my opinion the Mile Markers are better made than the standard warn hubs and they are quite a bit less.

 

Two different super duty's with warn premium hubs. Both are "loose" even with warns updated spiral ring, and they clunk when the trucks are in 4wd. Warn technical says that is "normal"

 

That's not good, I haven't had that problem with the standard warn hubs, but I am not a big fan of those either because the dial part is plastic, I worked on a truck a couple months ago that had a wheel bearing go bad and the heat melted the Warn hub. I replaced them with a set of Mile Markers and sent him on his way.
