My 07 keeps jumping out of 4 hi and will not go in to 4 Lo at all I can hold it in hi but if you turn or put any pull on it it jumps out if I hold it in it works great help please

 

is this a push button operation or is it an actual lever

 

Lever

 

Buddy of mine had a similar problem, his rails were torqued a bit. He straightened them out and all was good.

Also had yet another friend with a '06 with the same type of problem his T-case needed a master rebuild.

 

my 08 has something wrong with it too. if i dont miss my guess it has a broken shifting fork.

 

you might want to check to see if the lever is adjusted right. I know on my Jeep it would do that and I would have to climb under and readjust the rail from the shift lever that goes from inside the truck to the tcase itself. Its free to check, also check to make sure your tranny mounts are good. if they are sloppy the tcase could be moving under load causing it to come out of 4hi but this shouldnt effect it not going in to 4lo.
