Milling sound below car?

Post by oldscoolcart » 02 Mar 2023 09:41 am

Hi,

Car data: V340, 14.4S, CVT, 1988, ~170000 km's

Problem: recently I found the following:
after a local drive, some 10-15 km's I halted at home, left the engine running.
Put the shifter in 'N',
gave a light short strike on the accelerator pedal, a sort of 'milling' sound starts
under? the car.
After that strike the milling keeps going (foot away from the accelerator).
Pushing the central button on the shifter, the milling stops immediately.(and does not recur
-on that occasion(!)-).
The milling sound has something metallic and 'raw'.
Sounds as a worn bearing (to me)....

The milling sound is present when driving too, driving is normal for the rest of it.

Can someone of the nerds point me to what the cause is?

Thank you nerd. :)

There are a few members that know the CVT system well, you might be better off trying the volvo300mania Facebook group as it tends to get more views nowadays!
