Figure 1: Barnes 4WD Axle Swap Kit Components. This image displays all components included in the Barnes 4WD Axle Swap Kit. Visible parts include four U-bolts, two U-bolt plates, two spring perches, two shock brackets, and two shock mounting studs with associated hardware. These components are designed for installing a Ford 8.8 axle into a Jeep XJ/MJ.

Opsætning og installation

Installation of the Barnes 4WD Axle Swap Kit requires advanced mechanical skills and specialized equipment, including welding. It is recommended that this installation be performed by a certified professional or an experienced fabricator.

Generelle installationstrin:

1. Forberedelse: Securely lift the vehicle and support it on jack stands. Remove the existing rear axle assembly.
2. Axle Modification: Prepare the Ford 8.8 axle for installation. This may involve removing existing brackets and cleaning the axle tubes.
3. Komponentplacering: Position the new spring perches, shock brackets, and U-bolt plates onto the Ford 8.8 axle according to the vehicle's suspension geometry and desired ride height.
4. Svejsning: Permanently weld the spring perches and shock brackets to the axle tubes. Ensure proper alignment and strong, clean welds. This step is critical for safety and performance.
5. Axle Installation: Carefully position the modified Ford 8.8 axle under the vehicle. Connect the leaf springs using the provided U-bolts and plates. Attach the shocks to the new shock brackets using the mounting studs and hardware.
6. Afsluttende kontrol: Verify all connections are secure and torqued to specifications. Check for proper clearance of all components. Bleed brakes if necessary.

Note: Specific measurements and detailed welding procedures are beyond the scope of this general manual. Consult a professional or specialized fabrication guides for precise instructions.

Driftsmæssige overvejelser

Once installed, the Ford 8.8 axle, integrated with the Barnes 4WD kit, will provide enhanced structural integrity and improved performance for your Jeep XJ/MJ. Users should be aware of the following:

• Indbrudsperiode: After any major drivetrain modification, a break-in period for new gears and bearings is recommended. Consult your differential manufacturer's guidelines.
• Præstation: The larger ring and pinion, along with stronger axle shafts, contribute to a more robust drivetrain, suitable for demanding off-road conditions or increased vehicle loads.
• Justering: After installation, it is crucial to have a professional alignment performed to ensure proper vehicle handling and tire wear.

Opretholdelse

Regular maintenance is essential to ensure the longevity and safe operation of your vehicle after the axle swap. While the kit components themselves are largely maintenance-free once installed, the axle assembly requires attention:

• Differential Fluid: Regularly check and change the differential fluid according to the Ford 8.8 axle manufacturer's recommendations. This is crucial for gear and bearing health.
• Fastgørelsesmoment: Periodically inspect all bolts and nuts associated with the axle, suspension, and kit components for proper torque. Vibrations from off-road use can loosen fasteners.
• Visuel inspektion: Routinely inspect the welds, U-bolts, and other kit components for any signs of damage, corrosion, or fatigue. Address any issues promptly.
• Shock Condition: Check the condition of your shocks and shock mounts. Replace worn shocks as needed.

Fejlfinding

Should you encounter issues after the installation of your axle swap kit, consider the following common troubleshooting points:

• Vibrationer:
  • Check driveshaft angles. An axle swap can alter these, potentially requiring driveshaft modification or shims.
  • Inspect U-joint condition.
  • Verify wheel and tire balance.
• Noise from Axle:
  • Check differential fluid level and condition.
  • Listen for specific sounds (whining, clunking) to diagnose potential gear or bearing issues.
• Ujævn kørehøjde:
  • Ensure spring perches are welded evenly and at the correct height on both sides.
  • Verify leaf springs are seated correctly.
• Bremseproblemer:
  • Ensure brake lines are properly connected and bled.
  • Check for any leaks or damage to brake components.

For complex issues, it is always advisable to consult with a qualified automotive technician specializing in drivetrain modifications.
