| test 1
Engage the steering on a ab line. slowly pull up with the steering engaged still. foot on clutch and brake.
Does the front wheel slowly creep and turn to one side? can take 10 minutes to see this happen.
If so there is an updated relief valve that will fix this. It will also take out about a 5 to 10 cm random wobble out of the line
Test 2
tune up the steering with an implements hydraulics engaged.
ie and auto height system, air seeder fan or something else with constant flow.
Disengage the hydraulics
does the steering performance change?
if so could be a steering/brake priority regulation valve issue.
These are 2 simple checks to do if your dealer has checked steering relief, High and low pressure standby for main hydraulic pump and it still steers like crap. AND your nav and receiver are good then buy a complete steer valve. ( thats the entire block with the improvements not just the twin coil solenoid ).
P.S. Your orbital steer pump has got absolutely jack to do with autosteer performance. once engaged it uses oil from the main hydraulic pump ( same as your remote valves and three point linkage)
