Everyone needs to understand that when you make modifications to your vehicle it can affect many other factors. For example lately I have seen and heard of leaky axle seals on newer vehicles. Example is a Dana 44 axle, like we have on Rubiconís; it is recommend not going larger than a 33 in tire. What do we do? We install 35ís and 37ís. The larger tires (depending on your driving abilities) WILL cause more flex in your axle shaft, which WILL cause more movement than what the axle was built for. This movement/flex CAN cause the oil seal to start leaking. Any time you make a modification you REALLY need to understand the full effects on your vehicle that it may cause.
