KYB Suspension Strut Mount P/N:SM5218

$36.99

Description

Cushion road impacts and cut the noise and vibration that old, hardened insulators transmit into the cabin with the KYB strut mount SM5218, a direct-fit front replacement for the 1998-2001 Nissan Altima. This KYB strut mount tops the strut assembly and, on the front axle, its bearing plate also serves as the steering pivot and helps support vehicle weight — making it critical to smooth steering and wheel alignment.

OE-quality replacement: designed for the application to help optimize suspension performance.
Superior rubber: reduces noise, vibration and harshness from worn mounts.
Mount bearing: provides smoother steering and helps retain front-end alignment.
Matched-grade studs and nuts: for secure, correct installation.

If a worn or hardened front strut mount is the source of clunking over bumps, steering bind, or excess road noise, this suspension strut mount replaces it. Because it locates the top of the strut and acts as the steering pivot, replacing the left and right sides together is good practice for balanced handling.

What are the signs a strut mount may need replacing?

Clunking or knocking over bumps, increased road noise and vibration, or notchy, binding steering can be signs a worn or hardened front strut mount may need replacing. Diagnose the cause before replacing.

Does it include mounting hardware?

This KYB mount comes with matched-grade studs and nuts for secure installation. Consult the vehicle service information for correct torque and whether any original fasteners may be reused.
