Purchased new, never wrecked. When driving at low to moderate speeds and turning slightly right like merging onto a highway ramp, power steering seems to go loose/hesitate.
Pitman arm, tie rods and ball joints new. Freshly aligned - no problems. Power steering fluid level good, no whining from pump - no leaks from hoses.
Please help, out of ideas. Steering box, pump????

This vehicle comes with steering electronic variable orfice. Commonly it sets a trouble code when bad. Alot of time in history. Try changing the evo sensor. Its located inside the vehicle at the lower paert of the column.
