green bay, wi
during winter in noticed my driver side hub was acting unusual and when i removed it i noticed the tabs that hold the c clip down were worn off. i ran it like that for some time as the 4wd still worked but i never got a chance to really look into it. i bought a pair of hubs and put them on yesterday, only to have it do the same thing. i compared both the passenger and driver side with the hubs off but didnt noticed anything amiss between the two. not really sure how this part of the 4wd system works so any help is much appreciated.
 
Tabs that hold the c-clips down? :icon_confused:

Got any pics of what's happening?
 
on the inside of the hub itself there are 6 or 8 tabs that hold down a clip that holds the internals in. ill get some pics tomorrow.
 
pics. note the top 1/4" or so has been removed.

Ah, now I see what you're taking about.

Are your wheel bearing nuts coming loose? That's about the only thing I can think of that would cause that.
 
honestly ive no idea. i had both hubs off and compared the two but noticed no differences and the passenger side is just fine. ill have to pull the hub off again tomorrow but honestly im not real familiar with what its supposed to look like and such.
 
i dont think its the spindle, but im not sure how i would know if its bent or not.... here are some more pics, i think the spindle nut is rubbing on the inside of the hub.

hmm, my passenger side looks almost the same if i recall correctly. should the nut be tight? cause i can spin both sides by hand. im sorry if i sound (for lack of a better term) dumb but ive never worked on this type of 4wd system.
 
Yes... those nuts should be VERY tight (you're lucky your wheels haven't fallen off yet).

There's two nuts there, an inner nut, and an outer, with a locking washer in between them.

Tighten the first (inner) nut to 35 foot-pounds while spinning the rotor back & forth, then back it off ¼ turn, then retighten it to 15 INCH-pounds (basically just hand-tightening it).
Put the locking washer on, making sure the indexing pin is fitted into one of the holes,
Now tighten that outer nut to at least 225 ft-lbs (make sure the inner nut doesn't turn with it). Then reinstall the hubs (they should be OK still judging by your pics).

The other option is to have it towed to a shop and have them go over it (might not be a bad idea to inspect and repack those bearings as well). Make sure they tighten that outer nut to 225ft-lbs though (the books call for 150 which isn't enough, and often leads to this very issue).
 
There should be 2 nuts, a lock ring, spacer with a splined center hole, and a c clip(aka the Jesus clip)

One of the nuts has a PIN sticking out of it. This nut with the pin Must go in first and against the bearing With the Pin facing Outwards away from the bearing. get it tight but do not torque this nut down. Tight but you still need to be able to move the rotor freely.

Next the lockring slides down that grove in the spindle and the pin lines up with holes in the lockring.

Now the second nut. get it TIGHT Torque this one down, Check to make sure the rotor still spins without too much resistance( there WILL be some resistance) they have a bad habit of spinning slowly loose. Check it at least a couple times a year if you drive alot. and for the love of god. Dont beat on it with a chisel. get the right socket. 20 bucks at napa. You ARE going to use it more then once.

The spacer and the Jesus clip are to get the correct depth for the driveshaft to mesh with the hub.


From your last picture I do Not see the spacer or the C clip. and that outside locking nut looks like it has spun itself almost right off. which will eat the tabs on the hub.
 
Yes... those nuts should be VERY tight (you're lucky your wheels haven't fallen off yet).

funny that you say this, ive been driving the truck like this for some time now (months) without that happening. seems ill be spending my morning doing what you suggested.
 
I'll bet the spindle bearing is wasted. It'll keep killing it until until you replace it, if it is.

I torque my locknut to 150#. But I have stock rims and 31s, not offsets and 35s.

If you don't have a torque wrench you might not even be putting 150# on it. Especially with a crappy 4-point hub socket where you have to use most of your strength just to hold the little tits in the slots. My socket is in the garage at my other house so I don't know the part number, but it looks like this.

pulled the hub off again tonight, the spacers between the outer nut and jesus clip is mushroomed out (will post pics for your amusement) but the outer nut is now torqued to 150. i didnt check the bearings but the inner nut was still tight so im not too worried as of right now. ill be checking the passenger side just in case in a few minutes.
