Anyone contemplating this, what i did.
Tools needed in picture, M18 socket for caliper and bearing mount bolts.
Remove caliper and disc (M5? allen key), then bolts can be got at without any further dismantling.
I needed to use the blow lamp to expand the metal to loosen bolts, they are tight.
Best to remove the dsc sensor first.
Also, remove the two fwd bolts first, then the rears, otherwise you get the M18 socket trapped behind the shock absorber.
A lot of twisting the steering left and right.

I replaced mine a few months ago and I must admit the bolts are tight. I used a breaker bar instead of a blow torch as it seemed a "kinder" way to go (not that bolts have feelings, but you know what I mean!!!).

I was seeing dsc sensor plausibility codes 5EAC and 5E96 on obd for some time, these have now gone.
