In this guide, you will find instructions on how to change the rear lower suspension link (control arm) on 2017 and newer GM SUVs vehicles including Buick, Cadillac and Cadillac (see application section below).
This suspension link was poorly designed and can get easily bent on the earlier models. GM has redesigned this part, therefore we recommend getting the latest part instead and not installing a used part which could be the early version.
