Transfer case

[Lwhite5]

Last night I went to shift into 4 high and I had some grinding coming from TCase I had to be nearly stopped before the it would go into 4high without grinding. Before I could put into 4 high while running down the road no issues. Any ideas on what happened?

I never shift into 4x4 while driving. Not with these on the floor shifters.

Never had an issue. I shift in and out of 4hi all the time while driving.

I had hubs unlocked not sure if that makes a difference being that the front diff isn’t spinning and the rear dif is?

Yep, that'll do it. If you have locking hubs, they need to be locked for you to shift into 4Hi while moving. Otherwise, as you said, you have the front driveshaft stationary (not being driven by the front wheels) and you're trying to mesh two driveshafts.

Good info! Thanks for sharing that.

You're lucky you didn't blow up the transfer case doing that with the hubs unlocked. The gears need to be synced with speed in order to do that.
