Hate having to keep my rear seat in... stupid passengers should get their own jeeps. Definitely try to find the noise asap, my centering ball assembly in my fornt driveshaft ended up destroying my driveshaft and split my t-case in half. Its in the beginning of my build.
Maintain, wheel, upgrade, repeat.
