Hi. I've recently noticed a strange sound while driving, especially when not accelerating (therefore using the electric motor): it's a low-pitched, smooth, rotating rumbling sound, very regular, near the back, possibly associated with the drive chain(?). It's not loud and there is no clanging or clunking at all. I wonder if this is normal and I just started noticing it or...? It's driving just fine. Anyone? 

 

Also, I live in Vancouver, Canada. Anyone out there know of a good, reliable mechanic here? 

 

Thanks, 

Judy

Hi Judy

Thanks for your post. Does it get worse going around bends? for instance its louder when driving in electric around a left hand bend, but not as loud on a right hand bend?

Could be wheel hub bearing if it is

 

It sounds like a bearing of some kind.

Thanks. I haven’t noticed it getting worse when I turn any corners but will pay attention to see if it does. it doesn’t make any kind of grinding noise at all. It’s a very smooth, low, deep, rolling sound. 

bearings dont make grinding noises as such, only at the last minute they do. They will hum along for months and over time just get worse.

Glide along lets say doing 30, windows closed and listen out for going around corners if it slightly louder. the extra weight on the bearing will make it louder.

This would be the first place to look, doesn't mean it is the issue but any garage would first look at bearings if there is a rumble. Probably the easiest to fix as well.

Thank you!!! I’ll do that.
