Ok, I got a 2005 Jeep wrangler X with a 4 inch lift, and 33x12.50x15's. I recently highcentered my jeep on the axles while wheeling. I slide off in to some DEEP ruts, and got highcentered. After that incidednt I have been having a problem with my front end in the tune of when I turn my steering wheel, while taking off there is a popping and knocking noise coming from the front end. I have had a front end alignment done, and I greased, and checked everything on the front end but didn't see anything broke bent of just screwed. I am at a dead end with this problem. I don't know if my ujoints a screwed or if there is a hidden problem somewhere that I haven't found. I NEED HELP.  

If no noise when going straight, it is definitely the u-joints on the front axle stub shafts.
