Bad motor mount.
a clunk noise over bumps
They could squeak, rattle, bang , clunk.....
You have either run something over or your car is due for a service
You need to use the clutch and the shifter smoothly together!
most probably the noise is from the pipe expanding.
Need to check the rear u-joint in the drive shaft.
no. singing, its releasing music. talking, its releasing noise. lol :) but no, they are different.
Don't switch on the fly, that's just stupid. You'll need a whole system overhaul.
Clacking it's beak together to make the loud thundering noise. Like a Clunk.
Worn out bushing or steering joint probably.
check engine mounts
It depends on when you hear the noise, but it likely a joint in the front wheel drive unit.
