For the past 3 weeks, whilst driving slowly (40 km/hr) , I have noticed a creaking noise which appears to come from the boot. I had a friend sitting in the back with the boot floor and spare removed, and he thought it seemed to be a suspension noise.
Of course pressing the car up and down whilst stationery does not present the noise
I haven't yet crawled under to look - is there an anti-roll bar? Sometimes the rubbers get dusty and create a noise
