thanks Mac - I spoke with Jasper this morning, who remanufactured the axle, and they said they off-roading would not void the warranty as that is what the axle is meant to do - as long as I'm not abusing it, I have 3 years and 100k miles - and if the axle breaks, I can pay the difference and they will send me a Dana 44 or a 35 with different gearing
