I have a 2008 jk4.5 lift with 36 inch tires. Recently re-geared with 4.88. I drive it pretty hard for hunting season, and when it's in 4x4 I can hear what I think is the u- joints on the front drive shaft, cracking and popping. What can I do to eliminate this. Better drive shafts and u joints are a must I would say. I know it's the alignment of the front shaft. I want something tough and durable for the way I drive it. Any hints.
