For those not familiar with the LT 2042, it is a shaft driven, not belt driven. The transaxle shaft has a male "D" fitting and the hub is the female match to this. The hub is then attached/held to the transaxle shaft with a washer and bolt. The wheel then bolts onto the hub. Therein lies the problem, there is a wobble (wear between the shaft and axle) that allows this to occur. A washer can't be place there as the shaft is "D" slotted, not round; and a washer large enough to fit over the "D" fitting would simply slide up on the shaft.. Thanks....jn
