Hard steering

96 tacoma is all of the sudden super hard to steer (obviously harder at low speeds). No noise from power steering pump, plus just replaced the pump at the end of last spring. Fluid level looks fine but have noticed some leaking perhaps from lower of truck. thought it was oil but might be PS fluid. Son drives it to school and I seem to remember him saying he was slowly losing some fluid. Steering box or rack??? What do you guys think?

 

i would guess the power rack. But i have not dealt with the rack's much

taste the fluid, power steering fluid tastes bitter oil will taste more like grease
