easiest suspension job i have ever done to be honest..
you need a 7mm allen key ( which i didnt have) and a suitible swan neck spanner (which i didnt bother using).
i just used the impact wrench to undo the front top nuts and undid the bottom pinch bolt with the conventional ring spanner and breaker bar.
the rears were simple as abc.. just undid the bottom bolts on both sides whilst supporting the weight of the axle with a jack (makes it easy to remove the bolts ) once both bolts are out, remove the jack and the axle will drop and you can remove the springs..
