Hello I have a 2017 Silverado 5.3 LT. I was told I need to replace my steering rack bushings but can only find the driver's side bushings available. According to GM the passenger side bushings are a part of the gear and is a non sale item. I can't understand why they would only sell bushings for one side of the rack when a $200 job becomes a $1,200 job. Most steering gears do not have the two Mount bushings on either side of the gear. Has anyone replaced the rack bushings in the passenger side with an aftermarket part? Does anyone have the dimensions for the passenger side bushings? Photos of the mounts are included the side without visible rubber is the side that can be replaced and the side with visible rubber apparently cannot be replaced. Any help or advice or even explanation would be greatly appreciated.
