If you look at the bottom adjusting bolt on the power steering pump, the bolt takes a 15 mm socket. BUT, on the other side of the bracket is the “nut” that the adjusting bolt threads into. You can put a 15/16 socket on that. Then use a ratchet strap from the ratchet and socket to the outer tie rod end to pull it tight and hold it while you tighten all the bolts on the power steering pump.
