Problem coming out of 4X4

[big jimmy 91]

Wen't off road this weekend and when I un-locked the hubs , shirted into 2-HI there was a lot of vibration and rumbling noise as I tried to drive away. /forums/images/graemlins/confused.gif
I stopped , went in reverse for about 10 feet and it was back to normal ,what's up with that?
I thought you only had to reverse with auto hubs??
BTW the hubs were serviced and the TC shifts normal.
Is this caused by something not dissengaging when put into 2HI.
Anyone have any thoughts about this situation?? /forums/images/graemlins/thinking.gif

Probably just bound up the drive train driving it in 4WD in a good traction situation. I once bought a Suburban for $400 that wouldn’t move at all and the seller thought was all screwed up. I picked it up when he wasn’t there so that he wouldn’t be pissed and think I ripped him off. I brought a floor jack with me and when I jacked up the rear-end everything unwound like a spring; the rear tire turned almost three full revolutions. Then I unlocked the hubs and drove it home. There was nothing wrong with it. You probably had everything bound up and the hubs were hung up.

No locker for sure , just changed diff fluids and it looked the same as an open diff in my old 1/2 ton

Do you think it could be bound up when it's put into park on the side of the road , shifted into 2HI , then unlock the hubs??

I sometimes have to back a few feet with my manuals, just depends on how much tension is on the hubs when you unlock them, just because you turn the knob, doesn't mean the insides are released yet.

Thats what i have noticed anyways. /forums/images/graemlins/dunno.gif

I also recently installed a locking device in my front, and geez it likes to do some weird stuff. Thinkin about spoolin it now.

So this is not something leading to bigger problems then.
Thanks for the reply's

BTW . what type of locker did you install?

Well i hate to admit what i installed, but just to clarify, it was free, and it is a temporary thing i was just trying out to see how much better traction would be. It has helped out a bit, but still releases too much.

Let's just say /forums/images/graemlins/ignore.gif,,,,it's factory /forums/images/graemlins/doah.gif

I posted last week about one of those , never seen one before .

How harsh would a spool be in the front?

I dunno, it's the same as welding though, was going to try it out sometime soon. As long as you don't take turns too hard or have a heavy foot, i don't see any problems, yes you definately run the risk of breaking axles more, but isn't thay part of this hobby, finding out what works and what doesn't? Attempting new things and making thing "better"
Going to try it out either way, no matter how many people say otherwise.
