The gap between the stut tower and the stut top is totally normal. But they should be the same size gap - I can get my little finger in them both and they are the same.
I did our lasses up in summer - service,full front and rear shocks, springs, brakes, bushes, new arms, re-con steering rack, dunlop tyres - went mad on it and now it is making the odd noise from front N/S. But everything looks and feels as it should.
Wondering if its the C.V joint going?
I guess I'll have to have that out and check it over - it's nice weather at least
