Torque mounting screws to 42 lb.-ft.  (57 N•m). Step 3.  Inspect splines on top of steering shaft and on top of steering valve column for damage (see paragraph 12- 3). Replace damaged steering column (see paragraph 12-3). 16.  STEERING WHEEL TURNS WITH NO RESISTANCE AND CAUSES NO FRAME MOVEMENT. Step 1.  Check steering wheel retaining nut for looseness (see paragraph 12-2). Torque nut to 50 lb. ft.  (68 N•m). Step 2.  Inspect steering column and steering support for damage or broken parts (see paragraph 12-3). Replace damaged steering column (see paragraph 12-3). Step 3.  Inspect for leaking hydraulic lines, hoses, and fittings. Tighten all hydraulic lines, hoses, and fittings.
