Installation Notes

Verify vehicle year, make, model, and front right lower position before installation. This part uses a bolt-on mounting type and a tapered stud, so the mating surfaces and fasteners should be inspected carefully during service. Because no grease fitting is included and the joint is not greaseable, installation should focus on correct alignment, clean mounting points, and proper torque procedures for the application.
