Spring Pad Bushing

The Whiteline Performance Spring Pad Bushing (W73404) is a polyurethane coil spring isolator engineered for the front suspension of Toyota midsize SUVs from 1991 to 2007. This bushing replaces the factory rubber isolator to reduce suspension noise, improve spring seating, and enhance vibration isolation characteristics while maintaining OEM-level ride quality and load capacity.

Whiteline Performance specializes in polyurethane suspension bushings and isolators that bridge the gap between factory comfort and performance-oriented handling. The spring pad bushing sits at the interface between the coil spring and the suspension strut mount, absorbing shock transmission and limiting lateral spring movement. The black polyurethane compound resists cracking, UV degradation, and ozone exposure—critical durability factors in high-temperature engine bay environments. Weighing 0.93 lbs, this is a direct bolt-in component requiring no suspension modifications or specialized tools beyond basic socket and wrench work.

This bushing is intended for Toyota SUV owners performing routine suspension maintenance, addressing worn-out isolators, or upgrading from degraded OEM rubber components. Symptoms of a failing spring pad include clunking sounds over bumps, reduced spring support, or visible cracking in the rubber. The Whiteline bushing (sold individually per unit) restores spring preload consistency and reduces harshness transmission to the chassis and cabin. Installation requires removing the strut assembly and unloading the spring—a task within reach of DIY technicians with basic suspension experience or professional shop environments performing front-end service.
