had the differential checked out on the buggy. The noise is coming from the chunk. Drained the oil and there is small metal pieces stuck to the magnetic drain plug. Flushed and added new oil, still noisy. This is what you call luck, bad luck right here at deer season.
No but I work on golf carts a lot (albeit, gas ones) and I have seen axle bearings fail. Shards in the oil may be evidence of this but really, if the diff oil has never been changed there should be metal sludge in there. I would have to see it to know what was going on there.
Changed the oil, it was dark, no water. Just a few metal shavings. Still noisy. The noise began months ago, and was only real noticeable when going fast. Then recently, the noise became loud at any speed. Now it's loud. What's the best way to fix? New rear end, axle etc. or parts to be replaced?
Put it in neutral and jack the rear end and manually spin the tires to listen for the noise to determine if it is in the diff. Might need to disable the electric brake if there is one. Come to think of it, you may need to uncouple the motor to free the diff from the motor.
If there is noise then it is in the diff. If not, it may be the motor bearings. The only way to diagnose that is uncoupling the motor from the diff and hit the go pedal while in forward.
I'm leaning on motor bearing. Using an old mechanic trick listening to the noise using a long screwdriver touching different areas. The loudest noise is where the motor bearing is. Thinking about pulling the motor to check it out.
One of our boys and I repaired the ezgo club car motor today. Put a new bearing in the motor and cleaned it up a bit. Runs like new and no noise. Old bearing was dry, but hadn't began coming apart yet. It was a job, not kidding.
