Installation Notes
Verify the vehicle position before ordering, since this part is listed for rear right upper and rear right lower locations depending on application. Confirm mounting hole diameter, arm length, and ball joint specifications against the original component before installation. Because the assembly is pre-greased and non-greaseable, no grease fitting is provided.
