Hi Everyone,
I’d like to see if someone could give me advice on a couple vibration issues i’m seeing. Here are the two issues:
1) When I’m going between 38-42 mph I’m experiencing a vibration that appears to increase with acceleration and is most intense at 40 mph. From what I have read it seems like possibly misalignment between motor/transmission or transmission/driveshaft? It has a 2 speed IE Drives transmission (based on Lenco drag racing trans). Since I bought the truck used I don’t have knowledge of the mating design between motor/trans/driveshaft. I've asked Jeff Barber at IE Drives (he has been extremely helpful) about the transmission, but I thought I would ask here in the meantime.
Here is a video showing the vibration at 40 mph: 40 mph Link
2) I’m also seeing a higher frequency vibration when amps are closest to zero and is independent of speed. I can feel it in the pedal and it feels more like an issue between the controller and motor. Here is a video showing the vibration at 0 amps: 0 amps Link
