its really easy,theres 2 bolts on the rear shocker top and bottom i just use the top one
jack van up and let rear wheel swing down a little but still keeping it on the ground a little,you can then see the top bolt located on the rear inner arch behind the tyre,unbolt the bolt and then jack up a little bit more and pop the spring out,fit new one then lower a little on the jack and refit the bolt,same other side obviously
I have just dropped in a set of 55's springs in the rear and now looking at the van the roof line looks nice and horizontal all the way through but the gaps between the tyres and the wheel arches front and back are quite a bit of difference I know I have got to adjust the front's but I like the look of it sitting nice and level and not nose pointing down I don't know if there is anything I can do any suggestions ???
