As far as I know, neither Moog nor NAPA have any parts listed for the 2001's yet. I know. I've tried. I'm rebuilding my track bar with a Luke's Link, and Energy Suspension bushings.
I've had to replace the steering gear, and will be replacing the steering pump, both with replacements from AGR, as they're the only ones I could find. The ball joints are also bad, those aren't available anywhere for the 2001's either. Except from a company in Texas I never heard of.
It'll probably be the last part of 2003 before any of the good suppliers like Moog have anything for the 2001. I hope.
