Mevotech Supreme Coil Spring Insulator P/N:MP904945
Cushion the coil spring and quiet the ride with the Mevotech Supreme Coil Spring Insulator MP905961, a rear lower insulator that drops in as a direct-fit replacement for the 1993-2002 Toyota Corolla. It seats between the coil spring and the spring seat, keeping metal off metal and helping isolate road vibration and noise.
Over time the original insulator can compress, harden, or crack, allowing the spring to contact the seat directly — a common source of creaks, squeaks, or clunks from the rear over bumps. If a worn insulator is the cause of the noise, this replaces it. Sold individually; the rear pair uses one on each side, so order two for a complete replacement.

This part cross-references / interchanges with the following part numbers:
What is a coil spring insulator?
It is a rubber pad that seats between the coil spring and the spring seat. It cushions the contact, limits metal-to-metal wear, and helps isolate road vibration and noise.
Which vehicles does the MP905961 fit?
It is a direct-fit replacement for the 1993-2002 Toyota Corolla. See the "Vehicles it fits" section to confirm the fit for your specific vehicle.
What is this insulator made of?
All moulded parts use 100% natural rubber, which the manufacturer specifies to provide the best durability.
What are the signs the insulator needs replacing?
A compressed, hardened, or cracked insulator can let the spring contact the seat directly, often causing creaks, squeaks, or clunks from the rear over bumps.
How many do I need?
It is sold individually. The rear uses one insulator per side, so order two if you plan to replace both sides for balanced results.
