I was thinking that will probably be my best bet, I would like to get my service done at Horsham, but I would prefer to get my suspension issues sorted before doing a long journey such as that.
I am probably worrying too much but I do get very strong humming and vibration from the front once I go above around 40mph. Hardly any vibration when I am turning, even slightly to the right, but lots when going straight or going left.
