With a couple of spare hours decided to change the front ARB bushes, as the new ones had been rolling around in the boot for a few weeks whilst I waited for a "weather window", phew... was a bit tight for space in there so only managed to get the driver side done before the light went. Wire brushed the calipers whilst I was at it, and then found a dirty great screw sticking out of the tyre when I came to put it back on, so at least that may have saved me some hassle on the way to work tomorrow. Back is sore now though!
