    Actuator works off vacuum, follow the vacuum lines from the actuator and make sure you don't have any leaks, there's no flipping fix, when they go bad it's usually the vacuum diaphram that's mounted on the front axle that goes, but I have seen rotted vacuum lines also.

    My in-law's went out last year. Turned out to be a corroded line. Good Luck.

    the vacuum lines that actuate the diaphragm for the fork is supplied from the tcase - there are a set of lines that come off the tcase and cross over the front cross member and its the usual spot where they rot or get hit with road debris, iv replaced mine twice so far with factory new prebent ones.

    late but- the cable is so so at best- got it installed and will be going back to vacuum when I replace it. Strips out the locking threads very easy.

    You can pull the vac thing off and switch the shift fork over to hold the collar locking the axle perm as a quick fix- ran that way over a year before I changed to the cable- vac motor seized on mine.

    You get about 10 years out of a stock vacuum set-up so why not spend about $100 and replace the vacuum actuator and steel lines to it and get another 10 years?

  11. What oil do I put back in the reservoir, where the fork slides left and right ? I read in a Haynes manual to use hypoid gear oil. It didn't say the weight. I'd guess plain 80-90 differential oil would be too heavy, esp. in the cold for the collar to slide left/right to engage/disengage the 4x4. The collar has to slide just so anyway for it to lock over the axles, which are butted together end-to-end.

    Would transmission fluid work in the little reservoir ? (passenger's side on the dana 60 axle).
