2002 CC DS Elec Rear end Noise
 

Hi,

I have a 2002 Club Car DS Electric and was trying to cycle the batteries by raising the rear end and running the cart. I noticed that the passenger wheel power spun but the drivers wheel struggle and stopped. Noise seems to becoming from trans or drivers rear axle. I drained the rear-end, found no shavings and replaced with Royal Purple 10w-30 with no improvement....I have attached a drop box video link. Thanks for any input or advise.

Running the motor like that with no load will cause damage! :shock:
Was it making the noise before you jacked it up and ran it?

Re: 2002 CC DS Elec Rear end Noise
 

Rear end 101: an open rear end (like these ones) will only spin one side at a time. Had you held the passenger side the driver's side would have spun. That is normal.

What isn't normal is that gnarly sound. Take your wheels and brake drums off and see if something is dragging or grinding. Whatever is causing that noise should be easy to spot when you find it.

Thanks for the reply. Do you think its a bearing? Its been stored all winter but I do remember a little noise from drivers rear wheel last summer. When I spin the wheel by hand I can feel a little resistants.

You should probably feel a little resistance - your brakes scrubbing lightly (as they should) will cause that. Only way to know for sure is to take a look, I'm not as experienced with rear ends on these as some of the other guys, but I'd venture to guess that if you don't find the problem in the brakes somewhere that you may be looking at a bearing issue. Hopefully someone with lots of experience like TahoeDawg will see this and confirm/deny. :thumbup:

my thoughts too

Re: 2002 CC DS Elec Rear end Noise
 

Can you make a video of this with it on the ground? These things make all kinds of noises when you rev them up high when they're up in the air. What's it sound like while you're driving it?

Yes........weather permitting I will try to get one uploaded this weekend. I am doing a lift kit, dash, and new steering wheel....old one went to the trash dump last Monday.

Ok no need for new video. Put the new steering wheel on, took it for a test ride, and no noise. Just a mild wind from the motor but that's normal. Seems a little slower then I remember though. One other issue that pops up once in awhile is while under way the motor slows and beeps. I let off and on the pedal which gets it back to normal. Thought maybe its a speed sensor issue so I did the recommended test which resulted normal. FYI thanks for the help and interest.

I noticed a few issues with some of these details.... The motor slows and beeps? That would mean that it was the IQ system, which came out in 2002 meaning you would have one of the first IQ cars. What confuses me is that the IQ motor was NEVER bolted onto a Kawasaki drive unit such as the one pictured in the video. Some series motors may have been, but not IQ. They were strictly mated to Graziano transaxles. Another issue is that the motor in the photo sounded and looked like a series motor which wouldn't have a speed sensor. A car without a speed sensor will not slow itself down and beep at you like you're mentioning. So help me figure out what's going on here. What's the serial number of your cart? Does the motor have a speed sensor on the end of it?
