This part cross-references Monroe Shocks & Struts 904949 for the same application.

Common Problems This Part Can Address

• Squeaking from hardened or deteriorated spring insulators
• Rattling noises from worn suspension mounting points
• Excess vibration transferred into the chassis
• Loss of isolation between the coil spring and its seat
• Noise complaints after suspension inspection or repair

Installation Notes and Tips

Install the SM5463 at the front lower spring location only on the listed Ford applications. Inspect the surrounding spring seat, strut, and mounting surfaces for wear before assembly, and replace any damaged suspension components as needed to restore proper fit and noise isolation. Verify year, model, and position before installation.
