I was told it was the worm gears inside the truetrac winding out. I'm going to try some redline shockproof oil instead. I've heard that helps a lot. I have been told the truetracs are noisy if you use synthetic gear oil because it is too slick for the worm gears.
That causes the play? The noise I am aware of and not bothered by. Is this something that would cause damage?
