I’ve been listening more carefully. I hear two distinct sounds. One is an orb type UFO sound that comes on when it’s in electric mode the other sounds like the electric motor itself.
This didn’t even enter my mind as a possibility but I’ll check - for me it happens with vertical movement - just need to figure out how to test this possible source
Sounds good - I’d go to a top notch alignment shop armed with OEM spec ranges and get that castor right— most folks have too little room in the back and ample room up front. I recognize my TH has more room up front because of the bumper shape but that only comes into play with 34-35 inch tires...
Your castor is way too positive ! There is no way you should have 1.5” in the back and rub up front (at full lock). I for sure don’t have that much space in the back - I got about 1” in the back at full lock on 285/70/17s.
