4x4 engagement problems
HI everyone im new here, and just recently acquired a 1994 ranger 4.0L v6 4x4, 5spd manual. Everything works great except for the 4 wheel drive. I jacked it up this morning and placed it on jackstands then clicked in 4x4.
The passenger side drive shaft moves and i can hear the hub clicking, but the tire doesnt turn. The driver side drive shaft wasent moving at all. I know nothing about 4 wheel drive hubs but am wondering if the hubs need to be replaced or if the problem lies further....seeing as the driver side driveshaft wasent turning when the 4 wheel drive was engaged does that mean that the problem is in the transfer case?
Thanks Greg

Thanks for all the quick replies...There factory automatic hubs and i have no idea what controls them. Im guessing it would be vacuum since there automatic?
What would cause only the one passenger side driveshaft to spin though? Unless thats normal?because if i have to tear into the front diff i dont think it'll be worth my time and money to fix the 4x4
Thanks again Greg

what could be is that the diff is an open diff, the left hub is engaged (vacuum) and there is enough resistance on the one tire to make the tire not spin, and the other hub is not engaged so there is less load on there...
when you say driveshaft, i assume you mean CV shaft? driveshafts go from tc to diff

From TRS: With automatic hubs, there is no need to stop or get out of the vehicle to lock them in. The spring-loaded hub automatically engages on the fly when the transfer case is shifted from 2WD into 4WD. The application of torque to the axle causes the splined collar inside the hub to slide on to the axles splined stub shaft and lock. http://www.therangerstation.com/tech...Diagnosis.html

if u have a 94 you should go with Warn hubs.....if the hubs are the problem. You can't tell they are bad if u put it on a jackstand and test it i put my truck on a lift got all 4 up in the air put it in 4x4 and they all spun but the hubs were bad. when the trucks on the ground like you said they need to push more power

When i had the truck on jackstands i had a friend click it in 4wheel drive while i watched the cv shafts. the passenger shaft spun and i could hear the hub clicking but the tire wouldnt move. The driver side shaft wasent moving at all even when reving the motor. I kinda thought that both cv shafts would turn though. is it possible only one turned because its a limited slip diff?
Im going to soak the hubs and clean the spindles tomorrow and ill post my results.

1994 trucks did not have any vacuum actuators.

Well after cleaning the spindles and hubs they still dont work and just make clicking noises with the 4wheel drive engaged. Ive already started looking at manual hub conversion kits and the cheapest ive seen so far is 240 shipped and thats through amazon. Thats also the warn kit with there 29071 hubs and warn 32720 spindle kit and the large socket. Are there any places that might sell it cheaper?
Thanks Greg

you will still need the conversion kit but i think they sell those on summit, or 4 wheel parts has a "bag" thats cheep and has everything you need
