Question 99 4x4 hub lock spins

[1Wild Bill]

Hi all-- I have a 99 with ESOF and locking hubs on the wheels. The driver side lock spins without hitting a detent. And, if I just place it at the "Auto" mark, it still doesn't lock in. The ESOF doesn't seem to actuate the 4x4 now either. Maybe something broke in the hub? Thanks for any replies...Bill

Hub

The hub is probly gone. If they aint took care of they will go bad. If u find out that is what your problem is for sure let me know. I have some. Single or in set. Thanks

Took driver side wheel off and found the vacuum hose cut off. Repaired hose, and removed both sides hubs, cleaned/lubed and all is good now. I must have an early 99 because the innerds are a little different than the ones described/pictured in this forum.

To help the life of them lock in hubs drive for about 20 miles remove them and regrease then unlock them. That will get them good and lubed up.
