My steering on my 575E feels disconnected. It steers but the wheel can be turned indefinitely with no stops at wheel lock. When I have a load in the bucket or the wheels in soft dirt while sitting still the steering wheel can be turned and the wheels won't move. Pressure test at the test port is normal, around 100 psi at rest and a little over 2000 psi when turning the wheel. It's the same in both directions. Any ideas?
As a guess, steering cylinder piston seals are bad, needs a seal kit.
That sounds like a good likely hood. I will look into rebuilding those.
