Vibration in 2nd - MY11 (SH) Forester manual.
Posted: Wed Aug 24, 2022 11:18 am
Interested in opinions; vibration/shake on Forester MY11 (SH) manual. 126,000km.
Car has a vibration of motor/box that is really only obvious in 2nd gear, accelerating between 30 to 40kmh.
Shake is kind of side-to-side oscilation felt through the drivers floor/pedals when torque is applied in that gear and speed.
Not so noticeable if downhill. Engine has no sense of there being a misfire - performs smoothly in all other gears.
Vibration/shake smooths out after 40kmh. Not noticeable in other gears around that speed range, only really in 2nd.
New tyres and balanced and aligned - no change.
So, what do people think as best bet for investigation?
a) CV?
b) prop shaft joints or carrier bearing?
c) other?
Thanks.
