I have a 94 cherokee xj, 4.0 i have 33.13.50 tsl's, when i turn the wheel i get a loud popping noise coming from the front end, i had a buddy get in and turn it back and forth while i was under the front and i couldn't really hear anything, the balljoints, tie-rod ends look decent, i'm not sure what could be making this noise, can anyone help me out? thanks..
