Since removing the butt strutt from my Zed she has developed a "knock" when applying the throttle or turning left. The noise appeared to eminate from the drivers rear quarter which led me to believe I'd forgotten to tighten the subframe bush. I checked it however it was tight, checked the caliper, the cables, the pads, the drive shaft etc etc but to no avail.
The final check, after several days was the wheel bolts - strangely they were very lose, not much past finger tight.
After taking the wheel off, and scratching my head, I noticed a spigot ring on the hub. Essential this had been sitting proud of the wheel between it and the hub. What it wasn't doing is compressing when the wheel bolts were tightened, so the knocking noise was the slight rotational movement of the wheel on the hub - fortunately there is no elongation of the bolt holes on the wheel.
The moral of the story: check the most minor of things and don't ignore any knocks or bangs that are a little out of the ordinary. Fortunately something made me hesitate and not take the car today so I'd say quite a lucky escape!
