GSP NCV51535 CV Axle Shaft Assembly Installation and Maintenance Manual

1. Introduction

This manual provides essential information for the proper installation, operation, and maintenance of your GSP NCV51535 CV Axle Shaft Assembly. GSP CV Axles are engineered to deliver original equipment (OE) fit, form, and function, utilizing premium materials and precise manufacturing processes to ensure smooth, vibration-free performance under various driving conditions.

The design incorporates high-grade neoprene boots for superior abrasion and temperature resistance, protecting the internal components. Each assembly is factory-lubricated with a specialized high-temperature Moly grease to minimize friction and wear, promoting long-term reliability.

2. Safety Information

Working on vehicle components can be hazardous. Always prioritize safety to prevent injury or damage to the vehicle. Professional installation by a certified mechanic is highly recommended.

• Always wear appropriate personal protective equipment, including safety glasses and gloves.
• Ensure the vehicle is securely supported on jack stands on a level surface before beginning any work. Never rely solely on a jack.
• Disconnect the vehicle's battery to prevent accidental electrical discharge.
• Use the correct tools for each task.
• Refer to your vehicle's specific service manual for detailed removal and installation procedures, including torque specifications.
• Keep hands and clothing clear of moving parts.

3. Product Components

Your package should contain the following:

• One (1) GSP NCV51535 CV Axle Shaft Assembly

4. Setup and Installation

This section provides general guidance. Always consult your vehicle's specific service manual for precise instructions and torque specifications.

4.1 Pre-Installation Checks

• Verify that the GSP NCV51535 axle is the correct part for your vehicle (Right Front / Passenger Side for select 2004-06 Mitsubishi Lancer models).
• Inspect the new axle for any visible damage to the boots, shaft, or joints.

4.2 General Installation Steps

1. Safely lift and support the vehicle. Remove the wheel.
2. Remove the brake caliper and rotor, securing them out of the way without straining the brake hose.
3. Loosen and remove the axle nut from the hub.
4. Disconnect necessary suspension components (e.g., lower ball joint, tie rod end) to allow the steering knuckle to pivot.
5. Carefully separate the outer CV joint from the hub.
6. Pry the inner CV joint from the transaxle, taking care not to damage the transaxle seal.
7. Install the new GSP NCV51535 CV Axle. Ensure the inner joint seats correctly into the transaxle and the outer joint slides smoothly into the hub.
8. Reconnect all suspension components, brake components, and the axle nut.
9. Torque all fasteners to the manufacturer's specifications.
10. Reinstall the wheel and lower the vehicle.

Note on ABS Sensor Ring: GSP axles are equipped with an ABS sensor ring (if originally available on the vehicle). This sensor ring will not affect installation or operation on non-ABS equipped vehicles.

5. Operating

Once properly installed, the GSP NCV51535 CV Axle Shaft Assembly should provide smooth and quiet power transfer to the wheel. During normal operation, you should not experience any unusual noises or vibrations originating from the axle.

• Smooth Performance: The precision machining and balancing of GSP axles contribute to a smooth, vibration-free driving experience.
• Quiet Operation: Properly functioning CV joints should operate silently.

6. Maintenance

The GSP NCV51535 CV Axle Shaft Assembly is designed for minimal maintenance due to its durable construction and factory lubrication.

• Boot Inspection: Periodically inspect the neoprene boots on both the inner and outer CV joints for cracks, tears, or signs of grease leakage. Boot integrity is crucial as it prevents contaminants from entering the joint and retains the lubricating grease.
• Lubrication: The axle is pre-lubricated with a high-temperature Moly grease. No additional lubrication is required unless a boot is damaged and replaced, in which case the joint should be cleaned and repacked with appropriate CV joint grease.

7. Troubleshooting

If you experience issues after installation, consider the following common troubleshooting points:

• Vibration during acceleration: This could indicate an issue with the inner CV joint or an imbalance. Recheck installation and ensure the axle is fully seated.
• Clicking or popping noise when turning: While typically a sign of a worn outer CV joint, if this occurs with a new axle, it may suggest improper seating of the joint in the hub or transaxle, or a damaged component during installation.
• Grease leaking from boots: Indicates a damaged or improperly clamped boot. This requires immediate attention to prevent joint failure.
• Clunking noise when shifting gears: Could be related to excessive play in the inner CV joint or improper seating.

If troubleshooting does not resolve the issue, it is recommended to consult a qualified automotive technician.
