Hey sorry for the late reply. I haven't had any issues yet (knock on wood) and have a done a ton of trails including MOAB. have been running stock axles since I bought the jeep in 2014 but got the 37's on in 2015. Only modification I have done to my stock axle is adding c-gussets. I wheel pretty conservative which is why my axles have lasted but i know its a matter of time as I have been looking at a set of ProRocks.
