I replaced my pitman and idler arms on my 2003 H2 about 6 months ago with a cheap brand.
Last week I put on a new steering gear box as it was shot and couldn't adjust it anymore. Everything was great except for a little play left in the steering still after it was replaced.Drove for a week with no issues.

So looking underneath today I noticed the pitman arm had play in it at the center link.

Ok...so I get a new Moog pitman arm and change it out.

Now, the steering binds up and is hard to turn at low rpm's and turning in the driveway slowly back and forth it makes a loud creaking noise?

-yes it's the correct pitman arm and yes it's full of fluid.

Any ideas?

 

Update...after sitting in the driveway all night it steered perfect all day today...
I'm thinking it had some debris or air in the system that cleared itself. I did notice that it gets hard to turn at low rpm's under braking. Time for a new PS pump I guess...the hydro boost control valve in the pump must be shot.
