Last night I was with my girl and going to eat out and I missed the restaurant turn. Made a U-turn but noticed that when I turned almost all the way and started going it felt like my truck was stuck in 4x4 (started skipping like it should on pavement). When I noticed it, I turned into the restaurant and clicked it into 4Hi, let it shift into 4Hi and then shifted back into 2Hi while rolling in neutral about 5MPH. I heard the transfer case and front acuator shift out of 4Hi and back into 2Hi. But thing is, when I tried to replicate it, it only has done it once when I pulled back into my driveway when getting home. When I jacked it up off of all 4s, only the rear 2 turn in 2Hi (normal duh), and all 4 turn in 4Hi (also normal duh) and when I shift it out of 4Hi and back into 2Hi, the rear 2 turn (again, normal) This is one more thing in a list of problems with the truck and I'm just about up to here (holds hand level with eyes) with it. She only has almost 243,000 miles. The other day I did uncrank my torsion bars a little so the ride is a little better and I never noitced it before I did it. The list: Transfer case noise Harder than normal shifts Total front end rebuild A/C belt tensioner replacement Door switch replace Brake overhaul So, What could be the possible cause for this? It wasn't shifted into 4 anytime this month.
