Westar ST-3910 Suspension Strut Mount - Front

Westar ST-3910 Front Suspension Strut Mount

Westar ST-3910 is a front suspension strut mount built for vehicles that need a secure upper strut attachment and controlled suspension movement. It is designed for 1993-1999 INFINITI Q45, 1995-1999 Nissan Maxima, and 1996-1999 INFINITI I30 front applications.

• Provides a pivot point for the suspension to rotate and maintain correct steering geometry
• Locks the strut and body together for a stable upper mounting point
• Includes noise-dampening support to reduce road noise and vibration transfer into the cabin
• Built with materials selected for the specific application and finished to help extend service life
• Direct replacement for front strut mount service on select INFINITI and Nissan models

Application Details

Compatible With 1996-1999 INFINITI I30, front; 1995-1999 Nissan Maxima, front mount; and 1994-1996 INFINITI Q45, front except Active Suspension. It also fits 1993 INFINITI Q45, front except Active Suspension, after 1/93. This part number, ST-3910, is a practical OE-style replacement for front suspension service on these vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 903910) for the same application.

Common Problems This Part Addresses

• Clunking or knocking from the front suspension upper mount area
• Excess vibration or harshness entering the cabin through the strut tower
• Loose or worn strut-to-body connection
• Steering response issues caused by worn upper strut support
• Uneven tire wear related to suspension movement outside normal geometry

Installation Notes and Tips

Install ST-3910 on the front suspension only and verify vehicle configuration before ordering, especially on INFINITI Q45 models with Active Suspension. Inspect the strut assembly, bearing surfaces, and surrounding hardware for wear before reassembly. Proper alignment is recommended after front strut mount replacement.

Quality Assurance

Westar manufactures this strut mount with application-specific materials and a protective finish intended to support long-term service in suspension use. The design focuses on secure mounting, controlled rotation, and noise isolation for front-end repair work on Nissan Maxima and INFINITI I30 and Q45 models.
