Remove the rear shock, the bolts on the coolant bottle and a good ratchet spanner.
You might be able to do it with out removing the shock, but more room to work with the shock off as you can move the coolant bottle out of the way a bit more and it will gives you an opportunity to check the linkage needle bearing for wear.
