- Inspect the bore of the flow control valve on the pump housing for scratches and wear.
- Slip the flow control valve back in the pump housing, and check that it moves in and out smoothly. If OK, go to step 4; if not, replace the pump as an assembly. The flow control valve is not available separately.

- Attach a hose (A) to the end of the flow control valve (B) as shown. Then submerge the flow control valve in a container of power steering fluid or solvent (C), and blow in the hose.
- If air bubbles leak through the valve at less than 98 kPa (1.0 kgf/cm2, 14.2 psi), replace the pump as an assembly. The flow control valve is not available separately.
- If the flow control valve tests OK, set it aside for reassembly later.

- Inspect the ball bearing by rotating the outer race slowly. If you feel any play (axial or radial) or roughness remove the faulty ball bearing (A), and install a new one (B).

- Inspect each part shown with an asterisk in the Exploded View; if any of them are worn or damaged, replace the pump as an assembly.
