Detailed Description

The KYB SM5323 strut mount bearing is a suspension bearing designed for the front of select Mitsubishi, Nissan, and INFINITI vehicles. As part of the KYB Mount Components line, it addresses the bearing plate function at the top of the strut, where steering movement and load transfer occur. For drivers searching for a front strut mount bearing for 1995-1999 Nissan Maxima, 1996-2004 Nissan Pathfinder, or 1997-2003 INFINITI QX4, this part provides a direct replacement option built around the original application.

Part number SM5323 is also relevant for 2002-2006 Mitsubishi Lancer and 1996-1999 INFINITI I30 front suspension service, as well as 1993-1996 INFINITI Q45 front applications without Active Suspension. The bearing is intended to restore consistent steering pivot action and support proper wheel alignment behavior after wear in the original mount bearing.

What It Helps Address

• Steering bind or rough steering feel from a worn front strut bearing
• Front-end alignment drift caused by bearing wear at the strut mount
• Noise or resistance during steering input at low speeds or while parking
• Uneven suspension response at the top of the front strut assembly
• Service needs on a Nissan Maxima strut mount bearing or Pathfinder front suspension bearing

Installation Notes and Tips

Install SM5323 on the front suspension only where listed in the fitment data. Verify the vehicle year, make, model, and notes before installation, especially for the 1993-1996 INFINITI Q45 without Active Suspension application. Because this component works at the strut mount and steering pivot point, inspect related mount and suspension parts for wear during service.
