power steering pump squeal at full lock - coyote with KRC pump

[toadster]

when I turn my steering wheel full lock, I get a squeal - maybe from the KRC power steering pump, belt, or maybe even rubbing against my elephant ears which aren't fully attached in go-kart mode

To tighten the pulley, I have done the following:

1. loosen the upper mount bolt, I've found that loosening this allows for rotation
2. loosen the lower bolt, this is the pivot bolt to pull to the passenger side to create more tension
3. as I hold tension, I tighten both bolts, but the pulley gets in the way a bit

what is the best way to create tension on this non-tensioner pulley setup?
