Well, the old 2004 QC 4x4 2500 cummins is pushing 104,000 miles and the front end is loose as a goose. Time to do some parts replacing.

On the list currently are Carli upper and lower ball joints (now that they have them).
new u-joints all around (front and rear drive shafts and front axle ends)
Thuren track bar
Steering box brace
Adjust bearing preload on steering box (or replace it if it can't be adjusted well).

But I also want to do the sway bar bushings and the control arm bushings. Anyone can recommend good brand of bushings for this?

I saw some out there called "Prothane", they seem to be good, but don't know.
