right had a tiny knocking sound for a while coming from my passenger side (only notice it if you listen very carefully) and some passengers have felt a tiny knock through floor by there feet too but i can not figure out cause. swapped spring, shockie, lower arms,bushes, anti roll bar, brakes and checked to see if i can find anything lose but nothing, is it possible that it could be down to drive shaft as some one said possible cv but unsure and don't want to drag shaft out for no reason

 

or steering rack could be fooked?

 

got a new rack to go in it when i swap engine over so will keep you informed
