help diagnosing steering problem

[brdd]

I have a 2002 GMC Safari AWD. 190,000 miles. New idler arms and draglink. Original ball joints. One year-old tie rods. When I turn all the way either right or left the steering gives a jerking and popping feel to it. It only does this when turned all the way. The steering box is visibly leaking fluid. Can you give me direction? Has anyone else experienced this issue?


Thanks in advance

Don't turn the wheels hard left or right to the stops and leave them there, it puts a LOT of strain on the pump.

Ok Look thats what I kind of put in one of my post Front Systm to delicate ...Thats the shaft that goes from your front differential it has a pack bearing inside and when you turn all the way it does that be careful you dont brake it...when turning while moving a bit fast it wont hpnd but normally when you go real slow or trying to park if to sharp Kang-kang!!!..this is one of the reason Im thinking of doing the front swap!!!
