ARB Front Locker Steering Issue

I need a little help here. I just recently installed a Dynatrac ProRock 44 front axle assembly w/ ARB locker, and RCV axles. I have been driving on this for about 150 miles. No issues in 4wheel Hi or 4 wheel Lo. Last night I installed my ARB compressor to engage the locker for the first time. When I test drove it last night to engage the locker, my jeep immediately turned to the right and I could not turn the wheel to the left. I thought I was going to rip the wheel off the column. I disengaged the locker and things were back to normal. Any ideas why I can't turn my steering wheel to the left while ARB locker is engaged?

???? Your ARB hates NASCAR or maybe its just because its from Australia and they drive on the other side of the road........it could be trying to save your life!!

Are both axles locked when the locker is on?

If you don't know jack each wheel off the ground one at a time when locked, you should not be able to rotate them.

A front locker will make turning on pavement difficult, but it shouldn't be impossible. Having a bad alignment could cause it to pull hard one way.

Another thought, do you have locking hubs?

To me, the only thing that makes any sense is a steering box issue. The locker would make it harder to steer but it should be equal. The pump doesn't differentiate between right or left, it just provides fluid pressure that is routed in the steering box by the steering wheel.

I called Tom Allen of PSC and he also thinks the problem is in the steering box. He said he has seen numerous problems with JK boxes and the boxes have a spring type shaft- think torsion bar- that can cause this issue. Call him in the AM.

Good luck.

Scott,
How would this only happen when the ARB is engaged? Seems to work fine without the front ARB engaged.
I would think a steering box issue would be present all the time, no?

Thanks for the input, I took the rig into a field last night. I engaged the front locker and turned the steering full left and full right while stopped. The steering was a very hard pull to the left at first but then after a few lefts and rights and it was good and had even pressure turning the wheel to full left and full right. So I drove it around at low speed and made some sharp turns everything seems to be fine now. I may look into a new steering box just to eliminate that variable. Thanks again.

Jon-
The locked ARB is adding resistance and exposing steering box issues. PSC said there is a shaft (like a torsion spring) in the box that can get damaged by off road use that prevents steering to one side under pressure. They said that it can semi reset by forcing and holding teh steering to that one side. They say this is why they are so quick to recommend ram assist on JKs.

Bear in mind in 2010 Jeep replaced the JK's Delphi POS steering box with a Chinese POS steering box. Waiting for someone like PSC or Howe to make a decent replacement that doesn't require a ram.
