R51 Pathfinder Heavy Steering

[Bohman731]

Hey guys, hoping to find some help. My 07 pathfinder steering is extremely heavy, especially at low speeds. Fluid is topped off and the power steering pressure sensor is also new. The pump hasnt made any noise but I'm wondering if its gone bad. Any ideas on how to diagnose this problem?

If there is a power steering control module , especially with ' variable ' steering , look there before getting into the hydraulics again , which you say seems ok and parts been replaced. My steering gets extremely heavy in my J30 when then ctrl box was disconnected , mostly at low speed parking , of course hi-way speeds not so bad ?
So you find that 'box' , unplug / plug / unplug .........plug back in during short drive-tests to notice if it's working at all !
