TOYOTA 90105-T0114 Control Arm Flange Bolt

The TOYOTA 90105-T0114 is an OEM-quality, high-tensile flange bolt (control arm mounting bolt) that plays a critical role in the safe and stable operation of the vehicle's suspension system. This specialized fastener connects the control arm directly to the subframe or chassis, ensuring proper suspension geometry and stable wheel road holding.

Technical Features and Functions:

• Integrated Flange Design: The integrated flange (washer) beneath the bolt head evenly distributes clamping force across the mating surface. This prevents material deformation and minimizes the risk of loosening caused by vibration, without the need for a separate washer.
• Superior Material Quality: Manufactured to genuine TOYOTA specifications from high-tensile steel, it reliably withstands continuous dynamic loads and shear forces acting on the suspension.
• Corrosion Protection: Finished with a specialized surface treatment that provides effective protection against rust caused by moisture, mud, road salt, and other environmental elements.

When is Replacement Necessary?

Suspension mounting hardware is continuously exposed to environmental elements and mechanical stress. Bolt replacement is recommended in the following cases:

• When replacing the control arm or related suspension bushings (factory service procedures often specify that stressed fasteners should be replaced after disassembly).
• Visible corrosion, rust, or thread damage.
• After a severe suspension impact (such as hitting deep potholes, curbing, or collision) where the bolt may have stretched or deformed.
