On 10/10/24 I posted the above response. I believe the first two items in the list are actually the same issue. In July I had a clunking noise (one clunk) that only happened when letting off the gas. My dealership tightened the nuts on the rear axle and the noise disappeared. About 2 weeks after that visit I started hearing a faint rotating knocking sound related to the drivetrain (meaning the knock slowed as I was slowing) when I let off the gas (25 or less), it was especially prevalent when letting off the gas going down a hill. This is all street driving so you can hear just about everything when the radio was off. I knew the dealership wouldn't do much about it so I kept driving figuring the knock would get louder. A month after it started, it continued to get louder so I took it into the dealership and they tried the "lock tight" fix. It didn't help. I drove it for another month or so before I took it back in. They convinced Polaris to replace the all driveshafts. That didn't work either. I drove it for another month or two before I took it back in. This time the dealership convinced Polaris to replace the rear axles. They put on the new axles along with the "lock tight" fix. The noise is no longer there (although I've only driven it 20 miles or so). They want me to report back if I start to hear anything.
Our machine has 5300+ miles on it. We use it to run errands, trail ride, technical trail riding, noxious weed spraying and any other excuse to ride it.
The following was over a 5 mos. period.
- Single clunk when letting off the gas, 25 mph or less.
- fixed by tightening the rear axle nuts
- Rotating noise started 2 weeks later when letting off the gas, 25 mph or less
- could hear the noise better on the driver's side with the window down
- mainly prevalent when letting off gas going down a hill
- they tried fixing with lock tight, didn't work
- Noise started to get louder and starting knocking when accelerating and driving at constant speed
- could hear the noise better on the driver's side with the window down
- the knock was generally louder when just starting to drive and when it was colder outside
- they replaced the driveshafts, didn't resolve anything
- Noise continued to get louder and more prevalent
- could hear the noise better on the driver's side with the window down
- I removed the interior driveshaft cover to see if it was louder, I couldn't hear any of the knock coming from that area
- they replaced the rear axles along with the lock tight fix, the knock is gone (for now)
