Okay thanks damn truck has been nothing but a headache drive it maybe 2 times a month every time I do somethings broken lol gonna try to pull it apart this weekend

 

If nothing's able to free-rotate with Warns unlocked AND t-case in 2HI, it could be the t-case. I would start by disconnecting the front driveshaft from the t-case and see if anything frees up.

This is a pitfall of having a vehicle you don't drive often. We have two PSDs and an IDI, but we typically only drive on the weekends. We have to remind ourselves to switch out so no one truck stands unused for too long. That's when things tend to either fail or just get hung up (parking brake cables are a prime example).

 

Ok I'll try that madpouge but if I can spin drivers side shaft by hand would that rule out transfer case problem?

 

Not sure if it's normal or related but also with the truck in park and shut off with hubs in free position and truck in 2wd I can spin the front driveshaft by hand?

 

Wait - in post #12 you said neither shaft moves. Now in post #18 you say you can spin the driver's side. Which is it?

With hubs unlocked and t-case in 2HI, the front driveshaft should spin by hand, yes. That actually suggests the T-case is okay.

When you're trying to spin the passenger side shaft by hand, is the steering pointed dead straight ahead?

 

yes that is normal but is both axles turning too?

 

Hey sorry for the confusion and thanks for being patient with me. When truck is parked wheels straight , truck off and hubs in free with truck in 2wd I can spin the drivers side shaft by hand but not passenger side. On another not and where I think the confusion started was I had a friend drive the truck forward in my driveway this morning while I looked at both front driveshaft and axle shafts and both shafts did not move and driveshaft did not spin? This was at a very low rate of speed with hubs in free position and in 2wd on the floor

 

Okay, that clarifies things a lot. It's good, sort of, that none of the shafts turn while driving in 2HI with the hubs unlocked. That tells me that those items working properly. So the remaining issue is the passenger side shaft not free-turning by hand.

That's probably NOT the u-joint, since it happens with the wheels straight ahead. With the wheels straight ahead, the u-joint does not have to articulate, so even if it were jammed, the shaft should still _rotate_ on its axis, since it's perfectly straight (u-joint not articulated) when the steering is straight ahead.

One sign of a bad u-joint is when the shaft will turn by hand with the steering straight ahead, but can't be turned by hand when the steering is turned left or right. That indicates the joint is jamming when it's articulated. But that's not what you're experiencing.

To my mind, that leaves, as the prime suspect anyway, something going on in the diff holding up that axle shaft. Doesn't rule out something in the wheel bearing, etc., just seems to point more to the diff / axle shaft.

 

Thanks for the info sounds exspensive if i need to have axle rebuilt or shaft replaced guess I won't fully know how bad till diff cover gets pulled and shaft removed? I'm pretty confident with most things but rebuilding axle would be the first time for that

 

Axle rebuild isn't that tough, it just takes some time and maybe a few new tools

 

With the hubs unlocked, and the transfer case in 2 high, the front drive shaft should not turn while driving. With the truck parked, you should be able to rotate the front drive shaft by hand. The front drive shaft should turn if the hubs are locked in, or if the transfer case is in4 high or 4 low, while driving.

 

Yea I understand that now. my main problem right now is I can't move my passenger side shaft it's jammed after I was driving down the road and my truck decided it wanted to pull right hard and sharp . and I'm getting a interminte grinding sqreeching noise while driving that gets faster with speed

 

The noise and pulling MAY be a separate issue, related to brakes. Just another thing to check while you're tearing into things.

 

shouldnt be all brakes ball joints tierods ect new with moog parts less than 50 miles on them as well as re greased wheel bearings and u joints but will definitely check hopefully Tear into that side on Sunday or Monday

 

Well found the issue wasn't different related lots of carnage! Pictures to follow
