I went to lock my hubs last week in preparation for 4wd, and noticed one was already locked. Weird. Now I've been checking and every couple of days - 100-150 miles - my left hub is either locked or not in the snapped free position. Any ideas on this?

 

Check 'em after parking in a public area, just a quick walk-around. Grocery store, restaurant, etc.. Good habit to get into.

Hubs locking themselves? Totally lost on that one.

Thank you,

That is a new one on me. Try taking it off and look for rust or dirt and see what happens…Mark

 

Thanks guys, was hoping it's a common easy thing, wonder if maybe the springs are just worn in the mechanism. Maybe I'll experiment with some stiffer springs when I'm home this weekend.

I had the hubs apart a few weeks to grease the wheel bearings and install the missing pins in my locknut.
I was pretty careful to not overlube the splines of the locking mechanism, but they do turn pretty easy.

 

IMHO being the location is Orange County in SoCal the most likely explanation is kids seeing your locking hubs and knowing that having one of them locked can cause damage to your running gear do then lock one maliciously.

Naw I'm up in eastern Washington working. I've been keeping a close eye on the truck and I doubt its people messing with them. I can't figure out how to edit my profile, but I'm in nampa, ID now
