Seized half shaft

[kj4ltc]

Hey guys, just picked up a 83 K10 Scottsdale. When I bought it the front drive shaft was in the tool box, so after looking through a few things I fear my trouble is more than a bad 4x4 hub. The factory auto lockouts are still in place. With all tires on the ground if I turn the pinion yoke the drivers side half shaft spins at the steering knuckle, on the ground I cannot spin the passenger u joint at the knuckle. Today I jacked up the passenger side of the front axle and the tire spins fine but it does not spin the half shaft, and again if I spin the pinion yoke the drivers side half shaft spins. I have not yet opened the differential up to look for anything damaged or broken. Anyone experienced this or know what it may be? Thanks in advance!

Update!!! Put a socket extension through the drivers side axle u joint, and when I turn the pinion yoke my passenger side half shaft and tire turn....but if I turn the tire by it self the axle doesn't turn....possibly just the lockouts?

Sounds like the passenger side is working how it should with an auto hub. So it would seem like the driver side auto hub does not lock.

Well, you'd be correct.. finally got some time to get the truck up on stands and pull the lockout covers....nothing left on the drivers side lol
