I have a 1999 SkyTrak serial Number 9655 with rear wheel tracking problems. I have gone through the re-alignment process in the manual many times but the rear wheels quickly get out of sync with the front wheels.
You may have a piston seal leaking on one of the steering cylinders. It'll leak off and the steering will wander and get crooked.
That makes sense I’ll check them out. Thanks
Did you find the issue? I had this issue on a JCB and it turned out to be a sensor that registered the position of the wheels.
I rebuild both of the rear steering cylinders and that seems to of fixed my problem.
