The weirdest thing happened just then! I read about your top mounts and then on my way home mine started creaking really badly from the o/s/f and it clunks when on full lock! I have tightened up my strut bolts hoping its them! Its creaking when I brake like yours and when I accelerate like yours! I hope the bearings arnt too hard to change but the top mounts on my coilys came already on the from another owner on here. So might try sapping them to the ones from my old struts. How hard is it to swap them??
Coincidence! I've never done it, it's a shock out job so id say easier than fitting coilovers but still a pain in the ar5e
