Common Repair Uses

• Front-end noise from worn strut or spring components
• Sagging ride height on the front left corner
• Excessive bounce or reduced damping control
• Uneven front suspension response after component wear
• Need for a complete front left strut assembly replacement

Installation Notes

Install on the front left position only for the listed Lexus applications. Verify spring orientation, mount alignment, and suspension fastener condition before installation. Because this is a complete assembly, it helps reduce the time required compared with rebuilding a strut from separate parts. Always confirm vehicle year, model, and position against the fitment data before service.

Monroe backs the Quick-Strut line with more than 100 years of suspension product development, and this assembly is engineered to restore factory ride height and ride performance for the specified applications. The part is fit checked and ride tested as part of Monroe’s product validation process.
