just noticed a squeaking noise , initially when I get in and out of the car. Thought at first it was something to do with the seat but when I push down on the boot above rear tyres it happens or push onto rear tyres themselves. Its more prominent on drivers o/s than on near side. The shocks seem ok and were only done 2 years ago anyway. Too dark to see much else at the moment and tbh wouldnt really know what I should be looking at. MOT is due mid feb, so hope it isnt too ominous

.Anyone any ideas what it could be and what to get checked out?
