LEFT side Dorman used to be a quality manufacturer but they have a product that is made in China. Materials made in China are very questionable. I have found that within a few months the quality of the rubber used for the bushings and chassis grease fittings begins to deteriorate and crack. Then you can do this job over and over again! LOOK FOR US product! So goods made in China are not "OE" quality, OE has lasted 25 years or more. And another note: the left side is different (Dorman 520-134), also from China and CANNOT be lubricated. right side (520-133) LUBRICATE! Glad I can bold a page!
