Product Description
This genuine Toyota (OEM: 90101-10204) mounting bolt is a critical fastener engineered specifically for securely attaching the brake dust cover (splash shield) to the steering knuckle arm. This premium-quality OEM component guarantees an exact fit and maximum reliability within the vehicle's suspension and braking systems.
Technical Specifications and Function
- Application: Fastening the dust cover to the steering knuckle arm.
- Material Quality: High-strength hardened alloy steel engineered to withstand continuous mechanical stress and vibrations affecting the chassis.
- Surface Treatment: Specialized anti-corrosion coating (galvanized or dacromet) protecting the bolt against road salt, moisture, and road grime.
- Thread Design: Precision thread pitch designed to prevent loosening and ensure a stable, secure hold.
Role of the Dust Cover Mounting Bolt
The dust cover (brake disc splash shield) protects brake system components, wheel bearings, and steering knuckle joints from dust, dirt, water, and kicked-up stones. This specialized bolt ensures that the shield remains firmly anchored even under severe vibration and harsh road conditions, preventing shield deformation or contact with the brake disc, which could cause unwanted noise and premature wear.
When Should the Bolt Be Replaced?
- Corrosion and Rust: Suspension and chassis components are heavily exposed to moisture. Severely corroded bolts lose tensile strength and are prone to breaking.
- Damaged Threads: Thread stripping or cross-threading can occur during maintenance or brake servicing due to improper torque or misalignment.
- Mechanical Damage: Heavy impacts to the suspension or collision damage can cause the bolt to shear or deform.
For safe driving, it is always recommended to use new genuine OEM fasteners whenever servicing chassis and brake system assemblies.
