hi ive seemed to develop some sort of knock as im driving at low speed is when i can hear it most is seem to get faster as the speed goes up
sounds like a drive shaft or similar

as i touch the brakes even very gently it stops completly

i cant see anything wrong with the prop or driveshafts i pulled all the brakes off and cleaned it all up and put back on it seemed to have stopped for a while but has now came back

the car is a turbo 2000 classic on a 200 plate but with the running gear from a 2005 wrx including driveshafts and gearbox and engine

Has anyone got any ideas as it getting very anoying?
