87 4runner SAS wont turn right :((

hey guys.. got a question to see if anyone can point me in the right direction.

was comming back from camping-snow wheeling over the weekend.. made the 2 hour trip home with no problems. was at a stop and making a right hand turn. midway through the turn it was like i lost power steering.. but even worse i could not steer it to the right.. even when i tried to muscle it just wasnt moving, after making a 3 point turn i was heading straight down the road again. at the next light i turned the wheel left and right with no problems at all.. steered right just fine. made it pretty much all the way home from there and it did it again when at a stop sign and making a right hand turn. i parked the truck last night, came out today and it still will not turn right. i dont see any visual problems at all.

the truck has welded spiders in the rear with arb in the front. i did use the arb over the weekend so im hoping its nothing with the front locker.

you guys have any ideas as to what i should look at first or a way to diag and find otu what is going on?

sorry for the long write up but i am very concerned
ty for your time

oh yeah and there are no problems when steering to the left

Does the steering wheel turn right at all? Or is it locked up?

When you turn left, does it turn It right to a sertain spot then stop or once you go left there is no going back kinda thing.

Wont turn Right or left sometimes

Hello, I have a 87 with S.A.S and a locker in the front that does the same thing. I don't think its the gearbox though, because it only does it for me when im in 4x4 and the front hubs are locked in. When i unlock 1 hub it wont do it, or when both hubs are locked in and it acts up if I back up a few feet sometimes it allows it to steer again.. This is driving me crazy also. I have checked for steering bind, ect... When it does happen it feels like someone put my wheels in a vise. Has anyone else had this problem or have anyother solutions besides the gearbox? thanks!

I bet both of you guys that had/have this turning issue have a broken birf bell..... and a chunk of it broke loose and is catching sometimes when you try to turn.

clint---reading your thread again, it looks like you have something else going on....are you sure the gear ratios match each other... front and rear? excuse the double post

Its normal for it to buck in 4wd on dry pavement, as your t-case couples your front and rear axles together with no slip on it like an awd center diff would have in other models.

Broken cv or birfield can cause no steering.

Before you slap a box on, jack the truck up and put it on jack stands. Try to steer. Disconnect the tie rod at the wheel one at a time and see if you regain steering. With it disconnected, steer the wheel by hand while spinning the wheel to see if it turns. If everthing turns fine when disconnected. move on to disconnecting the drag link at the pitman arm on the steering box. Then try steeering. If it still doesnt steer then you have a bad steering box.
