So I was out wheeling today and I noticed everytime I locked the front dif, my steering would bind up. I could only turn slightly left or right on flat ground. I had my wheels turned to the left once and I could not straighten them until I unlocked and and rocked back and forth a few times. Nothing in the steering was bound up as far as the tie rods etc. I did the durango box upgrade not to long ago, not sure if this could be part of the problem?? anyone have an ideas??
That is part of having a front locker. Did you upgrade your pump when you did the Durango box? The oem pump won't be able to keep up very well with the higher flow box and may contribute to that as well.
Could be a pump problem, might want to upgrade to a smaller diameter pulley for increased pump RPMs/ power close to idle/ low engine RPMs. If that won't cut it, get a better pump (ie. PSC).
I never really had problems on my XJs running 35s (occassionally needed to hit the throttle a bit to get a bit more power to the steering), but my ZJ really doesn't want to turn the wheels with front locker engaged even if I give it gas.
well just for an update, I went out today and everything worked fine. I could turn full stop to stop with no binding or anything. So now I dont know what to think. if I didnt get enough space between the box and frame would that cause any issues?
No I havnt checked it at full flex, I will do that today. I am going on a pretty rough trail so the problem should show itself again. The more I thought about it I think it might have something to do with flexing. maybe the pitman is binding against the drag link? And Timo it was hot where I was wheeling so I could see it overheating. but I also have an oil cooler on the PS pump.
If it starts binding again on the trail, check immediately for something not having enough room for steering. From the description you wrote I though it was doing it at all times when front locker was engaged, not just under full flex.
It is fairly common to run into some binding issues at full flex, many times you only notice the issues only when you get onto trails. Trying to checking every possible situation in the garage doesn't really work, don't ask me how I know
Ha ya sorry i kindof contradicted myself. The first time it did it I was in a bad spot flexed out. (wouldnt turn right) I had to unlock the locker and move back and forth a few times to get it to turn. then I moved it to a flat surface (pavement) stopped and locked the front and tried to turn back and forth. It would turn left a little, but wouldnt turn right past center. I cant get it to replicate itself since that day though. I went out wheeling a pretty rough trail yesterday it it worked like a champ with the axle locked or unlocked. Im guessing that spot I was in got something out of place, but it must have fixed itself haha I really dont know. I am just gonna keep wheeling it and keep an eye on it.
