jumps out four wheel drive

lock hubs only lock the wheels not transfer case. check for wear of shifter as it may not be going into gear all the way. Otherwise it is either a bent shift fork or shift sleeve inside the transfer case.

Only once up to speed it jumps out.

it still can be what I said. make sure it is full of fluid.

Transfer case is full of fluid.

then the tcase will have to come apart to find problem.

Jumps out of four wheel drive once get out of speed. check transfer case shifter light on the dash does lock in. Check cable linkages.

It werid it finally good now it seem fixed it self

It might start happening again which I would agree with HMAC300 on a transfer case problem.

Please let us know happens so it will help others.

Best, Ken

I found out the one tire had different tread pattern. Also unbalanced tire causing it to jump out
