How do I deal with worn EZGO axle splines?

My EZGO golf cart is showing signs of worn axle splines. It’s affecting the performance, and I’m worried about potential damage or even a breakdown. Has anyone dealt with this before?


I’ve been in your shoes. When my EZGO had similar symptoms, I found that replacing the axle and upgrading to heavy-duty hubs made a huge difference. It might seem like a big step, but it’s worth it for the peace of mind and improved performance.

Symptoms and Causes

  • Symptoms: Axle spline wear or stripping, unusual noises, inconsistent wheel movement.
  • Possible Causes: Heavy usage, large tires, incorrect installation, lack of maintenance.

Detailed Solutions and Steps

  1. Replace Axle and Use Heavy Duty Hubs
    • Steps:
      1. Identify the Correct Axle and Hub: Ensure you have the right model for your EZGO cart.
      2. Remove the Old Axle: Carefully disassemble the affected area, keeping track of all parts.
      3. Install the New Axle: Align the new axle correctly, ensuring it fits snugly.
      4. Install Heavy Duty Hubs: These are crucial for carts with larger tires or heavy usage.
      5. Test the Cart: After reassembly, test the cart to ensure everything is working smoothly.
    • Handy Tips: Always double-check the compatibility of the axle and hubs with your cart model. Consider using a torque wrench for precise installation.
    • Unique Info: Heavy-duty hubs are designed to withstand greater stress, reducing the likelihood of future spline stripping.
  2. Tighten Hubs Properly
    • Steps:
      1. Locate the Hub Nut: Find the hub nut that secures the wheel to the axle.
      2. Use a Torque Wrench: Tighten the hub nut to the manufacturer’s recommended torque setting.
      3. Recheck After Use: After a few rides, recheck the torque to ensure it hasn’t loosened.
    • Handy Tips: Regularly checking the torque on your hubs can prevent many common issues.
    • Unique Info: Over-tightening can be just as harmful as under-tightening. Always follow the specified torque settings.
  3. Check and Replace Battery
    • Steps:
      1. Test Each Battery: Use a multimeter to check the voltage and load capacity.
      2. Identify Faulty Batteries: Look for any that don’t meet the necessary specifications.
      3. Replace if Necessary: Swap out any batteries that are underperforming.
      4. Ensure Proper Connection: Check all cables and connections for proper fit and no corrosion.
    • Handy Tips: Keep the battery terminals clean and free of corrosion for optimal performance.
    • Unique Info: Sometimes, issues that seem mechanical can actually be electrical, stemming from battery problems.
  4. Use EZGO Parts and Proper Torque
    • Steps:
      1. Purchase Genuine Parts: Ensure you’re using EZGO parts for replacements.
      2. Install with Care: Follow the installation guide carefully, ensuring all parts are aligned.
      3. Torque to Specification: Use a torque wrench to tighten to the recommended 90 ft-lbs.
    • Handy Tips: Using OEM parts ensures better compatibility and often results in longer-lasting repairs.
    • Unique Info: Incorrect torque can lead to premature wear and failure of the parts.
  5. Apply Red Loctite to Axle and Hub
    • Steps:
      1. Clean the Surfaces: Make sure the axle and hub are free of dirt and grease.
      2. Apply Loctite: Apply a thin layer of Red Loctite to the mating surfaces.
      3. Assemble Parts: Put the axle and hub together and allow the Loctite to cure as per instructions.
    • Handy Tips: Red Loctite is perfect for permanent assemblies but ensure you don’t need to disassemble these parts frequently.
    • Unique Info: Loctite not only prevents loosening but also helps in sealing the parts against moisture and corrosion.
