I don't know how many people have noticed this but if you have a TRD Sway Bar, please take a quick look under your truck and inspect the bushing holders (that attach to diff), for fractures. I had a 2007 5.7 CM and removed before I sold vehicle in order to put on my 2010 CM. After cleaning the bar and bushing holders I noticed a fracture extending from one end to the other. I have never taken my Tundra offroad and had only 40k freeway miles with the sway bar on. Hellwig may be the way to go.... Please inspect and share your findings.
