i am new to these 4x4 wheelers and was wondering how does the driveshaft pop out? i am not real hard on my wheeler, just some occasional mudding, hauling the ice shack around, and going fast , is this an issue with a lift kit durability/breakage or is it just cuz some people wail that dog poop outta there wheelers the issue about driveshaft issues? also how many miles you guys got on your lifts? any problems ever?
