Installation Notes and Tips

Verify vehicle application by year, model, and front right lower rearward position before installation. Inspect adjacent suspension components, fasteners, and alignment settings during service. Because this assembly is non-adjustable, final alignment should be checked after installation. Confirm the threaded ball joint stud and 14.3 mm mounting hole dimensions match the original hardware and knuckle interface. Part number CB28124 should be installed on the specified Mercedes-Benz applications only.
