Humvee Steering Issue

[Mullaney]

Tires were just put on. The pump is new.

.
So, the pump worked before you put on the new tires?

I’m pretty sure. There are others who are running the same set up and have no issues. The tires were bought used so I’m not sure if that’s playing a part in it. The power steering works when you give it gas which is building the pressure needed.

My 2 cents. If you are getting enough pressure to move the tires when you rev the engine, then your pump is not putting out enough when at idle. Could be a bad pump, or leaking relief valve. Does the Hydroboost work ok? What happens when you pump the brakes while at idle? Are all the high pressure hoses hooked up in the proper sequence?

New pump installed due to the last one going out.
When I pump the brakes everything works as it should.
Brand new Hydroboost.
As far as the hoses not to sure on that.

I also have no leaks or noises at all. When lifted in the air the tires move freely with no issues.
