2wd works good. but when im in 2wd my front drive shaft spins. My transfer case locks in and unlocks with my 4x4 on the floor but the shaft always spins. Im not in 4x4 all the time just the shaft spins and seems to be locked in in just the axle and not my transfer case. Not sure if I have a vacuum problem in my axle?? my transfer case works fine my guess its in my axle. Any ideas????

 

The axle on the drivers side turns all the time and it will turn the drive shaft as well.

 

even in 2wd? My truck does but not my buddies. same year and his 4x4 works too

 

as long as your drivers tire is on the ground, it will spin when you are moving. if your buddys doesnt, then he either has a hub kit or there is something dreadfully wrong in his front end..

 

All the tires spin when on the ground and moving ... When im in 2wd my front drive shaft spins when im driving. on my buddies his drive shaft doesnt spin when he drives.

 

Weird. sounds like something is wrong with your truck.

Your "issue" is that you dont have a clue how a full time front end works. we have told you why your drive line spins in 2wd several times.

Now, if you still cant seem to get it, either jack up your front end and learn something, or sell the truck and get something more manageable with your obviously limited desire to understand how things work.

 

your truck is fine
