2014 Tundra SR5 POwer Steering

HI everybody, last year i purchased a 2014 Tundra SR5 2WD Doble Cab. power steering is not smooth, never was. fluid is on minimum. i find resistance making turns, mostly at low speeds.
Any advise if this is normal on this year. Any recommendation??. the Truck has 82000 miles and im the second owner.
not sure if making a fluid flush and adding new one will make any difference. the truck has no modifications and has stock wheels and tires 275/65 R18 Michelin Tires.

 

I would remove the fluid and fill with new, fluids degrade over time. Remove all you can, fill it back up. Drive it a few days and repeat, that should freshen that fluid. If still an issue after than start looking at PS pump, steering components.

 

I would put the truck on a lift and take a close look at suspension components to be sure there is no binding in your steering. Also check LBJs for wear. Fluid change not like to make a big difference unless someone put wrong fluid in it. PS fluid should easily last 100K.
