Tools and Materials Needed

Rebuilding a drive shaft requires specific tools and materials to ensure the job is done correctly. Here's a list of what you'll need:

• Drive Shaft Rebuild Kit: Includes new U-joints, seals, and other necessary components.
• Sockets and Wrenches: A set of metric sockets and wrenches.
• Pliers: Snap-ring pliers and standard pliers.
• Hammer: A soft-faced hammer or mallet.
• Grease Gun: For lubricating the U-joints.
• Bench Vise: To hold the drive shaft securely.
• Safety Glasses and Gloves: For personal protection.
• Penetrating Oil: To loosen stubborn bolts and joints.
• Grease: High-quality grease for U-joints.

Step-by-Step Rebuild Guide

Step 1: Remove the Drive Shaft

1. Prepare the ATV: Place the ATV on a level surface and engage the parking brake. It's also a good idea to disconnect the battery to prevent any electrical accidents.
2. Remove Skid Plates: If your ATV has skid plates, remove them to access the drive shaft.
3. Disconnect the Drive Shaft: Locate the drive shaft and identify the bolts or clamps connecting it to the differential and transmission. Use the appropriate sockets or wrenches to disconnect these fasteners.
4. Remove the Drive Shaft: Carefully remove the drive shaft from the ATV. It may be necessary to maneuver it around other components.

Step 2: Disassemble the Drive Shaft

1. Clean the Drive Shaft: Use shop rags to clean the drive shaft, removing any dirt, grease, or debris. This will make it easier to work on.
2. Remove the U-Joints:
   • Place the drive shaft in a bench vise, ensuring it is securely held.
   • Remove the snap rings or retaining clips from the U-joint yokes using snap-ring pliers.
   • Use a hammer and punch to drive out the old U-joints. If they are stuck, apply penetrating oil and let it sit for a while before trying again.
3. Inspect Components: Check the condition of the yokes, splines, and other components for wear or damage. Replace any parts that are worn or damaged.

Step 3: Install New U-Joints

1. Prepare the New U-Joints: Grease the new U-joints thoroughly. This will ensure smooth operation and prolong their lifespan.
2. Install the U-Joints:
   • Position the new U-joint in the yoke.
   • Use a hammer and punch or a U-joint press to carefully press the U-joint into place.
   • Ensure the U-joint is properly seated and the bearing caps are flush with the yoke.
3. Secure the U-Joints: Install the new snap rings or retaining clips to secure the U-joints in place.

Step 4: Reassemble the Drive Shaft

1. Grease the Splines: Apply a generous amount of grease to the splines of the drive shaft. This will help prevent wear and ensure smooth operation.
2. Reassemble the Drive Shaft Sections: If your drive shaft has multiple sections, reassemble them according to the manufacturer's instructions.
3. Inspect the Assembly: Double-check that all components are properly installed and secured.

Step 5: Reinstall the Drive Shaft

1. Position the Drive Shaft: Carefully position the drive shaft back into the ATV.
2. Connect the Drive Shaft: Align the drive shaft with the differential and transmission, and secure it using the bolts or clamps you removed earlier.
3. Tighten Fasteners: Tighten all fasteners to the manufacturer's specified torque. This is crucial to prevent loosening and ensure proper operation.
4. Reinstall Skid Plates: If you removed skid plates, reinstall them now.
5. Reconnect the Battery: If you disconnected the battery, reconnect it.
