Hey folks thanks for all the replies.

Yeah, I'm looking for something to undo & redo up wheel nuts and also to do up nuts and bolts when I'm feeling lazy, also for undoing rusted on stuff. I don't mind using hand tools, but when I'm stuffed, I'd kill to be able to just squeeze a trigger rather than yank on a spanner.

I don't have any 18v stuff and don't do anything heavier than work on the Patrol.

What sort of power would I need to undo a Patrol wheel nut? 100Nm, 300, 325????
