Technical Specifications

Installation Guide

The VAICO V20-0357 Mounting, axle beam is engineered for a tool-less installation approach that aligns with OEM procedures. Follow these steps for optimal results:

1. Preparation: Ensure the vehicle is securely lifted and supported on jack stands. Remove any existing axle beam or mounting hardware that may interfere with the new installation.
2. Positioning: Align the mounting holes of the new beam with the corresponding brackets on the rear axle assembly. Verify that the Ø77mm holes match precisely.
3. Screwing: Tighten the mounting bolts to the specified torque (typically 80–100 Nm) using a calibrated torque wrench. This ensures uniform load distribution.
4. Alignment Check: After securing the beam, perform a visual inspection to confirm that the axle remains straight and centered. Use a wheel alignment tool if necessary.
5. Final Inspection: Re-check all fasteners for tightness and inspect the anti-corrosive coating for any defects. Ensure no debris or foreign objects remain in the mounting area.

Maintenance Tips

• Regular Inspection: Periodically examine the axle beam for signs of wear, cracks, or corrosion. Early detection prevents catastrophic failures.
• Cleanliness: Keep the mounting area free from dirt and road salt. Use a mild detergent solution to clean surfaces before reassembly.
• Torque Verification: After driving for a few hundred kilometers, re-check the mounting bolts to ensure they remain within the specified torque range.
• Protective Coating: If the anti-corrosive paint shows signs of wear, consider applying a fresh coat to maintain protection.
