Hello again Sam.
Lots of great info for you from RUM there. It might interest you if I tell you that we found we could get the strut out of my boy's
Ibiza without dismantling the hub. It was a few years ago so forgive me if I forget the finer details. We left the top mount in place and removed the pinch bolt at the bottom of the strut. It's nut came off easily enough but the bolt itself was a b****r being rusted in place. Took half a tin of Plus Gas and some determined "persuading" with a power bar and my "rattle" gun. Once it was out I used a large screwdriver to wedge the hub open and levered the bottom arm down with a very big pry bar (actually an old Morris Marina half shaft) whilst hitting the hub with a lump hammer. There was a bit of obstructive corrosion making the bottom of the strut hang up but it eventually surrendered to the hammering (wooden block used to avoid hammer damage to hub).
Then the top mount bolts were removed without drama and the strut withdrawn under the wing. (anti roll bar link and brake pipe/sensor wire disconnected too) but I remember then having trouble undoing the top damper rod nut (after compressing the spring). Couldn't hold the damper rod with an Allen key but as the strut was being scrapped I just held the rod itself with a big pair of locking pliers (which damages the damper rod but that doesn't matter as the strut was being chucked).
So I suppose I'm saying there's more than one way to do this. On the face of it it all sounds quite easy and simple, and on a nearly new vehicle it probably is, but get a few years down the line and add in the effects of a few years worth of winter salt etc and it all gets a bit more exciting.
