Locking hubs

2002 Excursion, 7.3, 260k. The locking hubs are on the way out and I wonder what you guys think I should replace them with.

I use 4x4 now and then and wouldn't mind if I had to engage them manually if getting rid of the auto feature increased the longevity.

over 1/4 of a million miles and probably had limited love , heck they may need serviced only ( search Guzzle's )

these hubs function as manual hubs also so there is nothing to gain by losing the auto feature

if you were breaking hubs off road i might upgrade to a more metalic unit

just FYI if you didn't know OEM is a Warn hub

I have Mile Marker hubs and they are made better than the regular Warren hubs. They are all metal where as the Warrens have some plastic parts. Keep in mind that Warren makes two different kinds of hubs regular and the premium and the premium may be better with no plastic in them like the regular ones. I got my Mile Marker hubs for $130 on eBay and the Warren premiums run about $250 so I think the Mile Markers are a better deal. Stay away from the Superwinch hubs they are pure garbage I had one fail in less than a year.

Sounds like you have had better luck with them than I did. I put Superwinch hubs on mine and they where pure garbage. I had to pack them full of grease to keep them from rattling and I blew one out after only a year, some of the internal pieces are plastic. I replaced them with Mile Markers and haven't had an issue since. You can tell a big difference between the Mile Marker and Superwinch hubs the Mile Markers are bigger, heavier and all stainless.

I haven't seen barely any 4x4 hub section fail on the superduties. I would take them apart, clean and lube. Im willing to bet that's all you'll need. They work as manual hubs if you cap off the vacuum sections etc. There is only an Auto and Lock setting on them.

(Auto) lets the little vaccum pump engage the hubs if everything is sealed that is.
(Lock) makes them a manual engaged 4x4 hub. turning them to auto is essentially disengaging them etc....


Just plug the vacuum end and put caps on both the lines and hubs and now you have manual hubs.


heres the service link with nice pictures and everything etc.

My '02 had a set of MM hubs recently put on it before I bought it this past spring, so I'll prolly just leave them.

But it sure would be nice to not have to manually deal with them in the winter. Just how hard are the OEM vacuum hubs to keep operating properly? Once every couple of years a clean and grease while doing a brake inspection?

Malfunctions mostly have to do with the o-ring seals and vacuum lines.
If there is a vacuum leak anywhere the hubs will not engage.
IIRC there is a yellow o-ring on the backside of the hub that is overlooked.

With the age of our trucks the vacuum lines are pretty old and brittle

I just bought 2 sets of Warn Premium Lockouts for my trucks. I have a early 99 and 2001 F- 350's DRW. The weather has been very cold and haven't had time to get them installed yet. I just wanted to know they will work when I need them to work as a DRW is pretty much helpless with out them working. I haven't been on here for sometime and it is good to be back.
