TOYOTA 90119-08560 Steering Linkage Bolt with Washer

The genuine TOYOTA part number 90119-08560 is a premium-quality fastening bolt with an integrated washer (Bolt with washer, steering linkage). This specialized fastener is engineered for critical locations within the vehicle's steering system, where maximum safety and vibration resistance are essential requirements.

Technical Features and Product Benefits

• High-Tensile Material: Manufactured from a specially hardened steel alloy capable of withstanding the continuous shear and tensile forces generated during steering.
• Integrated Washer Design: The assembled washer evenly distributes clamping force across mating surfaces, preventing component deformation and minimizing the risk of vibration-induced loosening.
• Corrosion Protection: Features a specialized surface treatment (zinc plating / galvanization) providing long-lasting protection against moisture, mud, and road salt.
• Precise Thread Pitch: Exact thread manufacturing according to factory specifications guarantees a perfect fit and precise compliance with factory-specified tightening torques.

Role in the Vehicle and Maintenance Guide

Fastening bolts that secure the steering linkage and steering gear components directly impact driving safety. Due to continuous shocks and vibrations originating from the suspension and road surface, these fasteners are subject to extreme stress.

Replacement of the bolt is recommended in the following cases:

• Whenever the steering or suspension system is disassembled (safety standards dictate that critical fastening bolts should be replaced with new genuine components following disassembly).
• Upon visible signs of corrosion, rust, or material fatigue.
• In case of damaged or stretched threads resulting from over-torquing.
