Block the machine so the wheels are off the ground. Start the engine and see which side is turning. Raise the seat, remove the panel between your legs and remove the fender on the side that is turning. First thing to check is centering components for excessive loose movement. This is the bracket where the shock absorbers are mounted. Below the shocks is another link. The link is threaded. When you move the handles slightly there should be no movement without compressing one of the springs that are on theses links and under the bracket. If the link moves back and forth without compressing the springs you will need adjust the nuts on the link to remove the play.
If there is no play then remove the vertical link back at the pivot. Follow the linkage back from the handle and you will find the pivot. Adjust the lenght of the vertical linkage to change the position of the arm which controls the servos. It is a trial and error procedure. Adjust until the wheels stop rotating when the handles are released. On some LS180's you may not get the wheels to stop completely while the loader is off the ground. Get them as close to stopping as possible.
If you can not get the loader to stop creeping, when on the ground, the servos or internal components of the pump may be defective. At that point you might as well replace the pump.
