i just recently installed my rc 3.25in lift and a t-case lowering kit that it came with. now i hear a noise that sounds like its coming from my drive shaft. it only makes it when im moving and it sounds like its hitting something as its spinning. i first noticed it after we got a couple inches of snow and i figure it was hitting a piece of ice that got lodged up in my t case but i looked under there now and theres nothing. so my question is could it be that my u-joints are starting to go? or has anybody else had this problem before?
