does a toyota 4runner 1991 automatic trans uses a gearbox or rack & pinion?
IF YOU ARE TALKING ABOUT STEERING, IN 1991 THEY USED A GEARBOX. THEY WENT TO RACK AND PINION IN 1995 WITH THE MODEL CHANGE.
Keep in mind the steering gearbox uses ATF and not power steering fluid. Putting power steering fluid has been known to cause leaks coming from the gearbox.
