• Function: This bolt is critical to the rear axle assembly, fastening the cross-member to the chassis and supporting overall suspension alignment and load distribution.

Bolts securing suspension cross-members endure constant dynamic stress, heat, and exposure to moisture. Over time, this can lead to corrosion, stretching, or loss of clamp force, potentially compromising alignment and safety.

When to Replace:
• During rear subframe or cross-member removal/reinstallation
• If original bolts show corrosion, thread damage, or deformation
• When performing a complete suspension overhaul or alignment service

Replacing with a high-spec OE Match bolt restores correct torque strength and alignment accuracy, ensuring factory-level performance and reliability.
