KYB Suspension Strut Mount Kit P/N:SM5937
Quiet a rough, noisy front end with the KYB strut mount kit (SM5203), a direct-fit replacement for the 1997-2003 Infiniti QX4 and 1996-2004 Nissan Pathfinder. As the original mounts age, their rubber insulators harden and start transmitting the jarring, noise and vibration of road bumps straight into the cabin — this front strut mount and bearing assembly cushions those impacts to help restore a settled ride.
On these applications the front bearing plate is the steering pivot and supports vehicle weight, so it plays a key role in steering feel and wheel alignment. KYB builds this suspension strut mount kit as an OE-quality replacement designed for the specific application.
If hardened or worn strut mounts are the cause of your front-end noise, harshness or rough steering, this KYB kit replaces them.

What does the KYB SM5203 strut mount do?
It's a front strut mount and bearing assembly that cushions road impacts to reduce the noise and vibration old, hardened insulators transmit into the vehicle, while the bearing plate acts as the steering pivot and supports vehicle weight.

It's a direct-fit replacement for the 1997-2003 Infiniti QX4 and 1996-2004 Nissan Pathfinder. Check the "Vehicles it fits" section to confirm your exact year and engine.
Does the KYB SM5203 kit include hardware?
Yes. KYB supplies matched grade studs and nuts with the mount for a secure installation.
What are signs a worn strut mount may need replacing?
Increased noise, vibration and harshness, knocking or clunking over bumps, and steering that feels rough or imprecise can be signs the strut mounts may need replacing. Diagnose the cause before ordering.
Should I replace both front strut mounts at once?
For balanced steering feel and ride quality, it's best practice to replace the strut mounts on both sides of the front axle together rather than one at a time.
