I have a 01 cummins 4x4 with a 2in leveling kit and I have play in the weal and a poping sound when I turn one way (to the left) and thin when I go back. What could the coused be and what are my option for upgrade?

 

The popping sound seems like wheel bearings, as for upgrades I dont know, your proably need to replace ball joints, tierods, gear box. and wheel bearings. But jack your truck up and push up and down on your tires and see if they move if they do then its your wheel bearings, does your steering feel lose? if it does ball joints will help.

 

Could also be your steering shaft, they're notorious for wearing out prematurely. You can open the hood and grab it and give it a shake, see if it's loose. To be making a popping noise one of the joints would have to be pretty bad. Sounds like something in the linkage to me though. I've been through bearings three times and mine never popped, but that doesn't mean they can't I guess.

 

my steering box has play make sure to check tie rods, trac bar sway bar end links the whole front end parts etc. just like stated above

 

I had to replace the trac bar on mine and that helpd ALOT!! it was $150 but it was well worth it. be sure to check the tie rods, sway bar, u joints, and bearing als had to change bearings on mine!!!
