I just got a huge decrease in my 'steering wander' problem, by performing the 'lower steering column bushing' rebuild using a part my dad & I made. Report & pics here:

The decrease was a plesant surprise - I just did this to get rid of that super annoying 'clunk, rattle or poping' our trucks develop in the column.
What I didn't expect was the increased feeling of direct control that resulted.
Makes sense, my whole front end is new with all the stuff you guys already know about or have done :
Darin's Steering Stabilizer, Lukes Link Track Bar, Poly Control arms & sway bars, New Rancho 9000's, etc
I guess what this did was: with the stock steering column, when steering the truck, the steering column 'inner shaft' was skewing sideways, before actually moving the steering box main shaft.
I think the clunking was the noise that results from the shaft also skewing sideways inside the outer shell of the column when road shocks were transmitted back up the line to the steering wheel.
My road wander is now at 0 % better than even when it was new !
Too bad it took 9 years of R & D and all the help you guys could offer to get it that way !!
