Installation Notes and Tips

Verify the vehicle application before installation, especially on 1975-1977 Buick Century and Regal, Chevrolet El Camino and Malibu, Oldsmobile Cutlass variants, and Pontiac Grand LeMans, Grand Prix, and LeMans. Inspect related steering linkage components for wear before replacing the idler arm, and grease the fitting during service if required by your maintenance schedule.
