'Wobbly' sound which is directly linked to RPM...
Driving along in my GT with the windows down enjoying a rare spell of nice weather in the North East...no music on (which is even more rare), and noticed a 'wobbly' sound.
Started to experiment to see how it came and went, and it seems the sound is present at around 2,000rpm or more. It doesn't matter which gear, and car speed makes no difference. Dip the clutch and the sound disappears instantly, since the revs drop off.
It's quite difficult to hear if the sound disappears the higher the RPM goes due to the hybrid turbo sound masking it. From what I can hear, it doesn't disappear.
From this I'd say it can't be any of the final drive components, wheel bearings, driveshafts etc., and also could suggest it is directly related to the clutch/flywheel, since dipping the clutch makes the sound disappear.
The other side of the clutch/flywheel I'm unsure about...I'm thinking that if it was anything between the engine and the flywheel, dipping the clutch would make no difference since all the rotating parts are still rotating, albeit starting to slow down?
If so, I know the clutch is well on it's way out, a lot of slip especially in the higher gears where there is a lot of torque, so would a failing clutch/flywheel be consistent with this 'wobble' sound?
I'm already taking her to Dan (Pud) at Autolusso Penrith next weekend where amongst other things the clutch and flywheel are being changed for the SMF and GTA clutch.
Any thoughts on this 'wobble' sound in the meantime would be much appreciated
