I have been getting the clunking noise since I got the car but has bothered me but now I have MOT in next couple of months think I need to look in to repairing it I have read it could either be rear axle bushes or anti-roll bar bushes. Can anyone point me to right direction of checking, price to repair by a mechanic or just how to do fix it(preferably lots of pictures

)
Also my front end scraps on small bumps and driving of curbs at reasonable slow speed even though it hasn't been modified.
Thanks in advance
