Ball Joints, U Joints, Tie Rod Ends, Track Bar Mount, Steering Box, All Bolts/Nuts Attached to The Axle, Unit Bearing, Drag Link.....Your Guess is as any good as mine at this point. Like always lay under the front of your jeep and while it is in park have a friend turn the wheel back and forward slow and fast. That will narrow it down a whole bunch. Then carefully put your hand on whatever you think it is. If you feel what you can hear then bingo. Sounds like a good greasing all around will benefit you in this case. I am pretty OCD about grease. There is never too much
We just put this front axle in, got brand new ujoints and tie rod ends and my buddy greased the hell outta it, hes just like you. but thanks! had a feeling id be doing this
