If you just want a replacement bushing, the guy at Lukes links have urethane bushings for the track bar for about $12. 00. I bought a link and a bushing. It did tighen up my steering but I still have undiagnosed problems in my front end.
As for the Moog part, my local NAPA could not help me even though I had the Moog part number. No luck at two other chain parts houses either. The Moog (Federal Mogul) web site was a big fat ZERO too. I could not find any suspension parts for my 99 2500.
I also called 4 Wheel Parts in CA about bushing. They would have to special order them from Energy Suspension and I did not want to wait that long. I also asked about sway bar bushings too. I guess I could call one of the speed shop places and see if they have better delivery times and prices if I get back in the mood to tackle the sway bar.
