Hey guys I'm new to the forum. I'm trying to figure out why my 4wd will not engage. I have manual hubs and neither 4 hi or 4 low will work. Transfer case feels as though its working, 4 low is as it should feel but front wheels will not pull. Please help!!!

 

IS the front shaft turning? If you jack up the front, lock in the hubs, and spin one tire, does the driveshaft, or opposite tire turn?

 

best place to start is jacking the front axle up so both tires are off the ground and locking the hubs, should be able to spin the 1 tire and have the other tire spin too. it is possible that the hubs are not locking.

 

Actuator motor not engaging the axle?

 

The Hubs are locked and wheels still spin free. Drive shaft will not spin. Any thoughts?

 

the hubs click as though they are locking.

 

hubs are locked and wheels still spin free. Hubs click As though they are locked. Shaft does not turn by hand. Any thoughts?

 

You need to pull the hubs, and see what things look like.

 

does it have a cad unit on the axle? if 1 wheel spins while the other doesn't the cad could be causing issues or there is a possible issue with the hubs if everything else it working but the hubs are clicking like you have said

 

Yep, its the cad. Thanks a million!!
