could be the belt as well. I always try not to hold my wheel hard over like that. What you are likely hearing is the result of the pumps high pressure relief valve opening. Making the pump need more power that the loose belt can't provide, and it slips, or the pump whine/squeal because it is starving for fluid or damaged. Holding it hard over to lock keeps that valve open and creates extra heat in the fluid and valve, makes the pump work harder and generally creates extra wear on the system. Dunno maybe thats just me being "finnish" or OCD but I like to turn it till I hear or feel it lock then back just a bit to keep the system happier. That extra strain in my opinion is unlikely to make the jeep turn any tighter.
Check your belt, fluid quality and quantity could need a new belt or a new pump or just have a leak.
best of luck
