I had replaced all inner and outer tie rods, sleeves, pitman arm, and idler arm as all are worn out... I did alignment at my work (during after work time). sometime when I was driving on highway or road, hit the uneven or bump, I could feeling a pop.. it make me feel like upper or lower ball joint start to wear out? I did replaced the shocks (all fours)... I did test the stabilizer links- it is tight.. the front end tires are show no wear problems... it is independent front suspension...

Sometimes the shaft that runs from the steering column and the gearbox wears and it is known to cause a clunk that is not only heard but also felt in the steering wheel.

There is a aftermarket solution to the steering shaft bearing at the bottom of the steering column. http://rocksolidramtrucksteering.com/

it is not only feeling on steering wheel, I can feel it from floor where my feet on while cruising on highway...
