My Club Car’s gas engine just started making this constant, maddening knocking noise. It’s totally throwing off my game and stressing me out. Has anybody else dealt with this kind of issue? How did you fix it? I’m desperate for any suggestions or advice you might have!
Response
I had a similar issue with my Club Car a while back. It turned out to be the drive clutch buttons wearing out. I replaced them along with the button spring, and it worked like a charm. The noise was gone, and the ride was smooth again. It’s a pretty simple fix and doesn’t cost much either. Definitely worth trying.
