I have installed light racing C/O's made by ICON and camburg uniball uca's w/ a TC DD on my wifes 04 sequoia 4x4 ltd and have had great results. Tires are 275/55/r20 cooper zeon ltz and wheels are factory 20" TX edition from a Tundra with spidertrax spacers. recently installed a set of bilstein 5100 shocks on the rear and they seem to be fine. i had the truck aligned last week and the tech said the bushing on the rack needed to be replaced mainly the D shaped bushing on the passenger side. so yesterday i installed the TC rack bushing kit. the steering response seems great but when you turn the wheel at any speed the skid control light comes on and beeps. you can feel it in the brakes mainly and it sounds like something is rubbing/grinding on the front end under my feet. any help would be greatly appreciated.
