Re: Egg Shaped Tires or Driving Down a Washboard...that's what it feels like...Why?
You need to hook up a volt meter and see if you see surges on it.
I know nothing about regen, but could it be turning on and off? |

Yep, DMM is on the list, waiting for the father-in-law to bring over his Fluke. Seems like the most logical place to start, was just hoping someone would say "yep, I had that happen too and here's what fixed it"... Bit optimistic, but it's worth a try. Worst case, I be the guy to help someone else out when the same symptoms are posted in the future. That's the benefit of all our accumulated knowledge. |

There's a little weight stuck to the armature of these motors. It looks like a big blob of JB weld usually. If that weight slings off it'll cause the motor to vibrate and cause the symptom you're having. I've seen it often but it's usually with series cars that have no motor braking to keep them from running high enough RPMs to sling the weight, but it's definitely worth checking out.

Take off the back cover and watch the motor and see if it is jerking back and forth while you drive it,if it is it is most likely electrically.

Thanks TDZ71, we all appreciate your experience and contributions! I'll check that out, but the "vibration" feels more like a bent axle (verified not bent) than a hiigh freq vibe. I can't udate the first post where I should have said 2Hz, NOT 120 Hz. Is there anything in the IQ system that could cause a pulse of current to the motor vs smooth current delivery? Or is there something in the rear drive unit that could cause a pulse feeling while driving at higher speeds...cuz I can hear and feel the pulse, keeping in mind that it "feels" like a bent axle. |

It sure sounds like a bent front spindle or rear axle to me.

Check your front end components to make sure nothing is bent. Also make sure it's aligned to 1/8" Toe-In. Improper toe can make the car feel like it's hopping.

Re: Egg Shaped Tires or Driving Down a Washboard...that's what it feels like...Why?
after a 6" lift and HD springs front and rear i too have a hopping or bouncing going on with my cart. 2003 IQ DS. I cant stand it. I bought too bought new wheels and tires (was a good excuse) it has helped some but for the most part my symptoms are exactly like ur describing. This weekend I am going to check for surges, watch the motor, tow it with something etc. I have not checked my axles or fron hubs yet. I fixed alignment so it's not that.

Does your bouncing happen at full throttle or various speeds? I'll have to take hard look, but my bouncing seems to be most prevalent when the cart is at its max governed speed. This is why I think its electronics related. |
