Quiet Down Clunks and Restore Smooth Steering Return on an Aging QX4 or Pathfinder
A worn front strut mount is one of the most overlooked causes of clunking noises and stiff, uneven steering return on the QX4 and Pathfinder, since the bearing inside the mount lets the strut rotate as you turn the wheel. The KYB SM5203 front strut mount replaces that aging bearing and rubber isolator assembly with a direct fit unit designed to restore smooth strut rotation and quiet operation. It's built to the same fitment and durability standards KYB applies across its shock and strut mount lineup, giving you a straightforward way to eliminate one of the more common noise complaints on these trucks.

FAQ
What is the KYB SM5203?
It's a front strut mount and bearing assembly built by KYB as a direct fit replacement for the 1997 through 2003 Infiniti QX4 and 1996 through 2004 Nissan Pathfinder, designed to restore smooth strut rotation and quiet operation.
Is this mount sold individually or as a pair?
The SM5203 is sold individually, so two are needed to service both front strut mounts.
Should I replace both front strut mounts at the same time?
Replacing both front mounts together is generally recommended since wear tends to be similar on both sides and it helps keep steering feel balanced left to right.
What symptoms suggest my strut mount needs replacement?
Common signs include clunking noises over bumps or during turns, stiff or uneven steering wheel return after a turn, and a knocking sensation felt through the steering wheel.
Will I need an alignment after replacing this mount?
A basic alignment check is recommended any time front strut components are removed and reinstalled, since ride height and mounting angles can shift slightly during the repair.
Does this fit both 2WD and 4WD QX4 or Pathfinder models?
This strut mount is designed for the front suspension shared across QX4 and Pathfinder trims of the covered model years, but always confirm your specific configuration before ordering.
What tools are needed to install this mount?
A spring compressor is typically required to safely disassemble the strut assembly, along with basic hand tools and a way to support the vehicle.
Is there a warranty on this strut mount?
KYB backs its suspension components with a manufacturer warranty against defects in material and workmanship, consistent with its broader shock, strut, and mount lineup.
Install Instructions
- Raise and safely support the front of the vehicle on jack stands
- Remove the wheel and disconnect the top of the strut assembly from the vehicle
- Compress the spring using a proper spring compressor and remove the strut assembly
- Remove the worn strut mount from the top of the assembly
- Install the KYB SM5203 strut mount and reassemble the strut in reverse order
- Reinstall the strut assembly, torque all hardware to specification, and reinstall the wheel
