8. HIGH STEERING EFFORT IN BOTH DIRECTIONS

Step 1.

Remove universal joint (para 3-28b).

Check universal joint components for wear or damage that could cause binding (para 3-28b).

a. If universal joint components are worn or damaged, replace components (para 3-28b).

b. If components are not worn or damaged, proceed to step 2 below.

Step 2.

Check power steering pump delivery (perform steps 1 and 2 of Malfunction 7 above).

b. If flow and pressure are not low, proceed to step 5 below.

Step 3.

Remove control valve assembly from power steering pump (para 3-28f).

Inspect control valve for burrs or other deformities which could cause it to stick in valve bore.

Check control valve spring for cracks, breaks, and loss of tension.

a. If control valve sticks in valve bore, is burred, or is otherwise deformed, replace (para 3-28f). If

spring is cracked, broken, or permanently set, replace (para 3-28f).

b. If control valve assembly is not defective, reinstall (para 3-28f). Then proceed to step 4 below.

Remove power steering pump from engine (para 3-28f).

Check gear and coupling for wear or damage, and missing or broken gear teeth.

a. Replace gear or coupling if worn or damaged, or gear teeth missing or broken (para 3-28f).

b. If gear and coupling are not worn or damaged and gear teeth are not missing or broken, reinstall

power steering pump (para 3-28f). Proceed to step 5 below.
