I couldn't find a thread on this noise, so I'm hoping someone knows what this is....
Driving tonight, I heard a noise I haven't heard before. Just happened to have my radio off, at slow speed, and....
- Knocking noise, not overly metallic, not sharp pitched. Kind of like my son is tapping on the plastic bottom of the Sling with his plastic hammer.
- Sounds like maybe coming from centerline under the main body, or perhaps just behind seat.
- Light force. Can't feel vibration. Only hear it at 20 mph and below before vehicle and road noise drowns it out.
- Not tied to braking, accelerating, tire speed, or engine rpm. Doesn't sound all the time. Drove 100 ft without it, then 15 times in 10 seconds. Arrhythmic, no standard tempo.
- Not tied to road surface. Got it in smooth parking lot and slightly bumpy asphalt with no change in randomness.
- No discernable change in handling (I think?) and no lights or indications.
- Nothing visibly hung up under body of Sling, although did not look closely in belt area, since it doesn't act like it's related to the belt.
So...anyone have any ideas?
