Air con causing creaking

[ambermarine]

Had a strange event this morning with the car which may throw some light on past anomolies in the forum of creaking suspension.

I sat in the car for thirty minutes waiting for the wife to do the shop (she as banished me years ago as getting in the way) I had the Air con at max as the weather was scorching ,the Aircon was regassed last december when I had the cambelt done so it is icy.

When we set off on our return journey I noticed a creaking sound coming from in front of the firewall as I negotiated a slow passage through the car park,it seemed to occur when turning putting weight on either side of the car.

I switched off the air con and within a couple of minutes the creaking dissappeared I deduce that the pipes connecting the compressor and the condensor  and the matrix in the airbox had all become stiff and movement in the frame was  amplified by this .

The sound and sensation could have been associated with a worn bushing in the suspension but my car as no issues in that category as it as only done 50kmiles.

Not sure if this is related, Phil, but when I get stuck in traffic in warm/hot weather for a long period I get a creaking from the front suspension afterwards.  It never happens in normal driving, i.e. when I can keep moving except for a few minutes at traffic lights etc.  It seems to be heat-related, as if the bushes have dried out.  The following day, or even later the same day, when everything has cooled down, the creaking has gone.

in this exceptional heat there's all sorts of expansion stuff going on everywhere with the car .  a few heat related groans will probably vanish in more " normal " heat times methinks  .  I hope anyway
