Thanks for the pointers guys.
I will try from the top with the stubby 18mm first... But it looks tight in there.
If I have to drop the subframe any pointers ?
4x4 under the two arms coming off the back of it, then lower it on a floorjack? [ I will be under the
car on my back eventually, no lift ]. What torque is on those 2 big bolts ? How difficult to line it back
up when you jack it back up ? Anything to avoid snagging or ripping / pulling ? Thanks again !!!!
