My EZGO golf cart is making a squealing noise

My EZGO golf cart has started making this unbearable squealing noise every time I start it up. I’m worried it might be causing damage or could lead to a breakdown. Has anyone else experienced this?


What worked for me was tightening the starter/generator belt.

Solutions that Worked

1. Tightening the Starter/Generator Belt

  • What I Did: Checked and tightened the starter/generator belt as it was loose.
  • Outcome: The squealing noise stopped.
  • Personal Experience: After tightening the belt, the annoying squeal was gone. It’s a simple fix but can make a huge difference.
  • Estimated Cost: $0 – $10 (if you need tools)
  • Time Needed: 15 – 30 minutes
  • Steps:
    1. Locate the starter/generator belt.
    2. Check for slack or wear.
    3. Tighten the belt accordingly.
    4. Test the cart to see if the noise persists.
  • Expert Tip: Regularly check the tension of your starter/generator belt. A loose belt is a common cause of squealing noises in golf carts.

2. Applying Moly Grease on Bushings and Bolts

  • What I Did: Replaced worn bushings and applied moly grease on the new bushings and bolts.
  • Outcome: The squeaking noise was eliminated.
