I recently installed front and rear TJM air lockers in my 1991 HDJ81 Land Cruiser. The truck has 35" tires, and drives down the road very well. I have noticed that sometimes when I am in high range and I am stopped or at low speed the steering will become very stiff. Today I put the truck into low range and engaged the front lockers and when I tried to turn the steering wheel it was nearly impossible.
When I disengaged the front locker the steering acted normally.
Obviously my steering pump is weak, and cannot deal with the combination of the larger tires and the front locker. Are there any stronger steering pumps that will work on my LC? Anyone know the part number for the factory pump? Does anyone make a steering improver kit for the factory pump? (The old Saginaw pumps could be modified for higher pressure).
Any help would be appreciated.
