307 rear nearside clonk (again)

My 2002 307 here in NZ is also making a faint clonking sound from the
front right side when turning left, especially over a drive-in bump. I
will ask my local dealer to check the front-right anti-roll bar bush as
you recommended, after New Year. It only seems to happen after a heavy
rain downpour, which is curious. There is also a loud creak from the rear
suspension when deeply compressed (like when I get in the car), which may
also be a rubber bush. That said, I really like my three year old 307 and
few things bring me as much satisfaction and pleasure as taking it fast on
long and winding country roads. My old 306 was a better driving car,
certainly, the recently owned 2001 VW Golf was a German pudding without a
soul and as unreliable and expensive to repair as any car I have ever
owned, but I have learned to live with the 307's minor shortcomings and to
appreciate and enjoy it's generosity and forgiveness.

 

I wonder if heavy rain washes away oil and grease to some extent and
increases the noise of bits of suspension rubbing together?
