my 4 bolt control arm fix
 

This is what I have done to my really awkward 4 bolt control arm type, the bolts get stuck by the gear box and engine sump so you can't remove them unless you lift the engine and other than that they have always been a pain to get lined up and fit into the control arm thread in the standard way of fitting.
I'm sure many will disapprove, and also the picture/diagram is just awesome.

With the fix I use you can just hold the nut with a ring spanner while tightening the bolt, I also use some red locktite on the nut.
