Here's a question for y'all. When I drop my t-case into 4 (hi as it turns out, thought it was lo as well), the front tires lock up. When I put it back into 2 wheel it's fine again. :confused: Any possibilities? I did just get done pretty much rebuilding the front end, but it did this before I rebuilt it. Thanks

Siezed spindle bearings
Broken spiders
Broken u-joint.

Does it change of you shift the transfercase or when you lock/unlock a hub?
 
It's when they're engaged and the case is shifted. It can be shifted into 4 without hubs locked and it doesn't do it, IIRC. I can see the u/joint, it's fine. Don't know about the rest
 
I just disassembled the hubs down to the knuckle and repacked the bearings, greased everything and installed new hubs, so I doubt that's the problem. Guess I'll pull the diff cover and inspect the gears
 
Dont waste any time do you? 9:06 to 12:03.
I wish I was so motivated. :D

Also: I have no idea what is wrong. I wish I could help.
 
LOL no way man! Sorry for the confusion. I did it two weeks ago 'cause I needed to! Damn, I wish I was that motivated too! I could have done it easily, but I didn't need to, and was too busy sitting on my ass watching T.V. :haha:
 
On the wheel that is locking up......lock in the hub on that side only and do not put it in 4WD and see if it trys to lock. If it doesn't, have someone look at the axle while it is moving. (Do I need to tell you to be safe doing this??)
 
Safe...what's that?:eek1: :haha: Anyway, I'll give it a try. If I have someone look at the axle when I'm driving and it's not locking up, what am I looking for?
 
Anything unusual. Inner flopping, ujoint contacting knuckle,outer flopping, axle not turning, sparks, noise, etc.
 
I'll have my dad check it out soon. Further inspection shows BOTH wheels periodically lock up. They'll turn, lock up, free up, lock up, etc.
 
Yeah. Sounds like some kind of grenaded locking/limited slip device inside there.
 
damn...that would explain the noise I hear every now and again that sounds like metal grinding.:eek1: :o :haha: I've had more important things regarding my truck on my mind recently, and since it was only occasional and not severe, I ignored it:doah: Seems like I should give it some TLC, huh?

*update*

Well, I pulled the diff cover, and other than some nasty ass fluid, everything looks fine. I jack up the truck, lock in the hubs, drop the t-case into 4hi, go to turn the wheel, and the carrier, ring gear, and front drive shaft stop turning, plus I feel some resistance. The spiders are still rotating, but that's it. Is that normal?:confused:

Now that I think of it, could it be my t-case? Because when I have the hubs locked without the t-case engaged it rotates freely. Busted something in my 203 perhaps?
