Hi all,

My Bronco's been retrofitted with Warn Premium hubs, and for the last 8 years, they've always worked great. However, earlier this year, the driver's side hub stopped engaging. I could jack the front up, lock the hub, then turn tire, and the driveshaft wouldn't spin. (On the contrary, the passenger side works fine).

Since then, I've completely rebuilt the entire hub. New rotor, inner and outer wheel bearings, lock ring kit, caliper, brake pads, etc. etc. Properly lubricated and regreased everything. (I know the brakes are irrelevant, but just stating the extent of the work done).

The hub still won't engage.

If I take the cap off, I can manually press the mechanisms in, and it'll engage fine, and the whole system works. Everything seems to really work great. The problem seems to be that when I lock it, the cap just doesn't push everything in far enough to engage the hub. I contacted Warn and they thought it was the spring, so they sent me a new one, but the new one is actually shorter than the one that's currently in there. It seems like it just needs to push the hub in another 1/2" or so to make it engage.

I have no idea what to do. It's snowing and slick out, and I really need to get this working.

Any ideas?

 

Maybe contacting Warn again, have you checked that everything is fitting in right?. Remember the pin in the spindle nut has to be inside the safety washer or the fit won't be correct.

 

I contacted Warn, and unfortunately, they said they'll only replace them under warranty if I have the original receipt, which I don't, since they came on the Bronco when I got it.

I'll try pulling the hub open this week and see what I can see.
