I checked this "play" in my front wheel and it's very odd. It's more like play in the tyre on the rim. So, away to replace all bushes including front ARBs as well as the trailing arm ones, All ball joints, All wheels bearings and generally tart up underneath while everything's off.
priced it all up on TCB parts.
£317.77 for the lot minus the wheels bearings.TCB have a polybush kit as well which is included in this price.
