Way back in the day, on my 1986 Grand Wagoneer, the power steering gearbox leaked like Niagara Falls around the pitman arm.
It was a lifted rig and I think at some point in time, the steering took a hit and the sector shaft was damnaged, causing the seal to be compromised.
From advice I was given over on the Mothership, I purchased a Chevy S10 powering steering gearbox.
I replaced the OE unit with the newer S10 unit.
The S10 unit had three mounting holes, but it had a quicker ratio that provided a better driving experience.
Now, on my 1986 J20, while driving, it seems like turning the steering wheel takes more turns than I think it should.
I feel like I driving a school bus.
I really don't know if this is normal operation or not.
From what I was able to research, the ratio of the J20 power steering gear box is 16:1
I do know that the J20 has a larger bore (worm gear) than the standard Wagoneer, Cherokee and J10. (3/4 ton vs 1/2 ton)
My questions are:
1. Should a good working J20 powering steering gearbox takes a lots turns of the wheel from lock to lock?
2. Is there a GM/Saginaw powering steering gearbox from a 3/4 ton/1 ton rig that would have a quicker ratio than the OE Jeep unit?
3. Is there a recommended aftermarket, 3/4 ton rated, quick(er) ratio power steering gear for the J20?
