noises!!!! hhhmmmmm, the rear end could be the bearings/bushes in the rear beam, or spring or damper, cant really narrow it down, take a can of wd40 and spray areas mentioned (dont get any on brakes) then see if noise disappears!, clunking noises when changing gear, are they pressin clutch pedal??, sound stupid i know but some peeps get lazy and dont fully depress the clutch then wonder why they have difficulty changing gear, if not that then a clutch/gearbox prob???or broken engine mount causing engine to rick when changing gear??
