I have serviced many gearboxes on gm trucks and noted more travel out of the box on the bench than when it was installed in the truck, that is normal and proper.
I did not know that. I was always told that it was important that the steering not bind or hit before full travel.

Can you explain the pressure relief valve and how it works? I assume it was related to the internal stops, and not external contact. Otherwise wouldn't you be able to put your wheel against a curb and invoke the pressure relief? I'm not going to try that because I have nice wheels though.

Is it as simple as when the box encounters an obstruction it jacks the pressure, overrides a spring, and lets the fluid bypass? I had assume that could only happen at the box's internal stops.

I have never had a box apart, and only have an approximate understanding of ball bearings and sector gears and whatnot, so go easy on me!
