SPC xAxis sealed flex joint for 2007–2017 GMC Acadia replaces failed cross-axis ball joints on the rear upper control arm with a greased, booted joint that increases angularity and resists contaminants. The polished ball enhances durability while the sealed design retains grease and maintains NVH characteristics. This replacement offers up to 45° angularity and an easier installation compared with rubber or poly options.
