While waiting for new parts to arrive for 'Gertie' I decided to do some investigation work on my yellow Mk1. I'd noticed recently (On the rare occasions that it's been out that is!) that I had quite a severe clunking noise from the nearside rear. I suspected that the rear subframe bush was causing the problem. With the car supported on axle stands and the subframe allowed to hang down it was revealed that this indeed was the problem.
