Strange noise in reverse

Have just recently noticed a creaking groaning sort of noise when lifting clutch pedal up in reverse. Thought I had scraped the wing when reversing into the garage at first! All other forward gears are fine. If I am very light with clutch and very slow isn't that apparent. Have tried lifting clutch in reverse with hand brake on and can induce noise noticeably. Any ideas?

when you engage reverse with the handbrake, on the rear of the car lifts slightly due to the suspension setup..... just wondering if its the rear dampers squeaking as you are using a bit of them that dosent normally get used....as they normally get compressed not stretched.?.

Thanks for your replies. Unfortunately my Samba is now in hospital at the moment after a rear end attack by a bus! Tailgate badly dented, bumper scratched all over etc Hope all else is well - I miss it already! Have  Ford Galaxy as hire car and it's not a patch on it. Too big, too heavy, no fun!
