Hi folks, in the past few weeks my beloved 120K mile Ampera has developed 2 noises.
First noise: Superficial sounding click that times with wheel rotation while braking around slow tight left hand turns. Sounds and feels brake related and not with any knocking force noticeable.
Second noise started today, this one I'm worried about: Only just started so it's very subtle, from 30Mph onwards it sounds like a distant motorbike in the front left footwell (it's not a distant motorbike btw 😂). It relates to vehicle speed, it is no where near as high pitched as the transmission bearing noise videos I've seen on youtube, but could it be the early onset of it?
At 40mph it sounds like a regular cruising motorbike rpm, increases with speed. No difference when in neutral, possibly slightly more noticeable under hard acceleration or regening in 'L' mode.
What are the possible causes? And what are the cheapest fixes for said causes. Do I pray it's a wheel bearing and change the fronts one by one, or go balls to the wall trans bearing?
Thank you!!
