94 chev halfton

the transfer case is makin all the right noises, will go into low range n all, but hubs arent engaging.there is a solenoid on the front diff, anyone know what is the most likely problem. gonna take a test light to it when i get home from. fuse is good, thinkin loose wire but all seemed good. anyone had this problem before. really hoping cheap fix, and really like to have 4x for drivin the canyon next weekend if it snows.

It's the actuator on the front diff, isn't engaging the hubs and front end when u lock it into low, happens when it gets cold out or muddy/wet cuz they arnt sealed worth a shit, try pulling it out, cleaning it and cleaning the plug, if it still dosent work then ya it's fucked

If all else fails, buck up and buy a set of manual hubs?

Ford is good. Had a few meself, not many problems with the earlier ones, oldest I had was a 1970 and newest was a 1989. Bodys would rot before the drivetrains would go. AND, you had to go outside and turn the front hubs to get it into 4x4. Keep care of those units and they last and last. Yup, Ford is good.

if its earlier than 98 (i think) then its got the thermal linear actuator, which relies on heat to keep the plunger activated, they always fail, you can do the electric upgrade which costs as much as just putting in a posi-lok mechanical pull cable like i did.

yea i was fingering it was the actu, as i can here the tcase shifting. ill try pullin apart and cleanin, def pack it with dielec grease. it started not working in 4 lo, then after a couple weeks of mild abuse it stopped all together on my way to the snow mobile cabin on friday at stave. bald tires posi and 2wd=not alot of good on lose hill climbs.

IF you are going to keep fingering the actu! Better buy yourself a FIRSTAID

I got about 5 of em that still work and I'll probably burn through them pretty quick. Buddy of mine has a bolt setup that he just spins in when he wants to 4x. gotta crawl under, but no accidental disengagement.

That's the route I went, got mine at sport truck unlimited for around 216 taxes in, works great, installed in about 20 minutes. Make sure you pack the boot with grease! I think the unit bearings my cost at lordco were 145/side or something like that...

I`m not sure how the unit bearings are causing problems in this case.

unit bearings arent the prob for me, just one needs replace. 285 thou, bout time.

no sas for this girl, the 60 goes in the bronco.

ill check out stu in a week or two. looks like a good setup.

Unit bearing are the reason they have that actuator never needed it with normal manual hubs :dontknow:
