Product Description
The genuine Toyota leaf spring bushing (part number: 90385-18021) is a premium quality suspension component designed specifically to maintain vehicle stability, ride comfort, and safety. Bushings are crucial connecting elements between the suspension and chassis, absorbing vibrations and impacts originating from uneven road surfaces.
Technical Features and Function
The leaf spring bushing provides a flexible yet stable attachment of the leaf spring pack to the vehicle chassis or spring shackle. It facilitates controlled movement of the spring leaves during suspension cycles while minimizing metal-on-metal contact and structural stress.
- Superior Vibration Damping: The specialized rubber-metal composition effectively absorbs vibrations, significantly enhancing ride comfort and minimizing suspension noise.
- Durability and Resistance: Engineered to withstand harsh environmental conditions—such as mud, moisture, and road salt—as well as heavy mechanical loads.
- Precise Fit: As an original equipment manufacturer (OEM) part, it ensures exact geometric accuracy and seamless installation.

Symptoms of Wear
Bushings are standard wear items that deteriorate over time due to mechanical stress and aging. Common signs of wear or failure include:
- Squeaking, knocking, or clunking metallic noises from the suspension, particularly over rough roads or during cornering.
- Vague steering response, instability, or body sway under load.
- Visible cracking, dry rot, deformation, or debonding of the rubber from the metal sleeve.
- Uneven or accelerated tire wear on the rear axle.
To ensure road safety and prevent premature wear on adjacent suspension components, timely replacement of worn bushings is recommended, preferably in pairs per axle.
