My 2x4 burb has it real bad, bad enough that the ol lady won't drive it. I raised it up and the wheel bearings are a little loose so I cinched them back down. But the gear box has alot of slop in it, the sector shaft has enough play in it that the wheels have about 1" of side to side travel. I backed off the jam nut and ran the adjusting bolt down untill it made contact, about 3/4 of a turn then I backed it off about an 1/8th of a turn. The box is solid now and I am off for a test run. The box has leaks from everywhere so it is prolly on its way out.
