I get creaking noises (like a frog croaking) from both the front and back of the car whan going over speed bumps.
There are a number of speed bumps at work (20mph zone) and if I go over them at 10mph the car is silent increase the speed to between 10 and 20 and the creaking occurs, seems to be both front and back.
Seems to be mostly when it's damp or wet.
These have been replaced recently:
Bilstein B4 dampers front and rear
VX Spings front (with VX spring sleeves)
Top mount bearings (both sides)
Front drop links (both sides)
Rear Upper control arms (both sides)
I am pretty sure the rad mounts are the newer rubber type and not springs but not checked as I don't know where to look for them??
What else is left?
