After nearly 240,000 miles the rubbers on my lower control arm (or wishbone) were perished, and the lower balljoint (LBJ) was starting to feel questionable too.
This procedure is to replace both on the left hand side (i.e. Gearbox end of the engine). The procedure for the right hand side (i.e. Cambelt end) is almost exactly the same, but with one (fairly large caveat) - to access the front-mount bolts on the right hand side, you will need to raise that end of the engine by about 25mm. You can get away without this if you're very lucky (or have extremely shallow sockets) but for that side of the car, plan as if you're going to have to raise the engine slightly so that your ratchet doesn't foul on the sump.
Also, if you're doing the right hand side (offside), be very careful of the driveshaft - it's incredibly easy to accidentally pull the shaft out of the inner CV joint - if you do this you'll need to replace the driveshaft. It's a common occurrence when changing the offside control arm on the S60 and V70 apparently
I was in a bit of a hurry doing this job, and unfortunately forgot to take pictures. The pictures below were all taken after the fact.
