very hard to turn steering wheel to the right
Hello All, I hope that someone can give me some advice. All of the sudden, it is very hard to turn my steering wheel to the right. 1994 F150, 5.0, power steering, power brakes, automatic. It is as if the power steering has gone out, but only when turning the wheel to the right. Fluid level is fine, no leaks, belt is fine...I'm guessing ghe problem is in the steering box, but I would appreciate any helpful suggestions. If it is the steering box, is that a difficult job to replace?
Thanks in advance
