Question about 1986 Toyota 4Runner
So the truck was working great in 4 low and 4 high. We had a real bad snow and deep freexe out here over the last 3 weeks. The droped the truck into 4 low while in the snow and every thing was fine. Got home and pulled it back to 2 wheel drive and parked it. The next morning I went and put it back into 4 low and had no front movement or traction. SO I tryed 4 high and still nothing. I have been under the truck andthe drive line is still there, solid to movement by hand as shoud be.
I saw two electronic units by the transfer case, and I disconexcted them and re conected them, and still nothing. I dont see any linkage as the shift unit is a top loading shifter.
Can or does the self locking hub units burn out or freeze up on these 4 runners? and is there a way to fix them with out replacing them with manual locking hubs?
Any and all input would be great on this
The self locking hubs (or automatic hubs) are actuated by vacuum. The vacuum line is usually on the driver's side of the differential, towards the front of the vehicle on Toys. You might want to check it out and see if it's cracked, broken, or gone.
