I have a major headache. I own a 2006 H3. It started making a noise when driving. Mechanic checked and told me the bushings needed changing. He identified the 2 stabilizer bar bushings easily. He also said the single bushing in the middle of the other bar is a steering rack bushing. Does anyone have an idea where I can purchase one? Does it carry another name because I cant find steering rack bushing online anywhere. Thanks.
