Hi guys, I’ve been having an issue with my 4x4 system can’t figure it out. It’s a manual Tcase and whenever I put it into 4 wheel drive and drive over 5mph the truck is extremely hard to control, also whenever you try to disengage the 4 wheel drive it feels like the front right is still engaged and the front end bounces until I hear a loud bang and the truck will then finally go back into 2wd. Any help would be greatly appreciated!!!
