Mystery Solved!

[ubtripn]

So driving my truck still felt like piloting a boat on a lake even after I:

Replaced the upper and lower ball joints
Replaced the inner-outer tie rod ends
Replaced the Pitman arm
Replaced the Idler Arm
Replaced the inner & outer bearings
Replaced the shocks
Installed a heavy duty sway bar
Replaced the Rims and Tires

So I figured the only thing left was springs. They installed the springs then had me take a look at my shocks (The only parts I didn't install myself other than the springs.) They had been put on hand-tight. Guess they forgot to use the impact wrench. 3 had worked themselves loose and were missing the top nuts. Anyway, I had the original shop replace the shocks and now my truck drives like new!

Lesson learned.
