- EPS assist consistent - more assist at low speed, less at highway speed?
- Steering torque sensor reading symmetrically in both directions per scan live data?
- EPS and steering angle sensor relearned after any alignment or steering component replacement?
- Battery charging system voltage adequate - weak charging system causes EPS warnings at low RPM?
Hydraulic Power Steering Checks
Hydraulic system specific inspection.
- Power steering fluid at correct level?
- PS fluid condition acceptable - not burned, foamy, or contaminated?
- PS pump quiet - no whine, groan, or scream?
- All PS hoses dry with no leaks at pressure line, return line, or rack connections?
- PS pump pressure within OEM spec - typically 1000-1500 PSI maximum?
Steering Rack and Mechanical Components
Inspect the rack, tie rods, and mechanical steering components.
- Steering rack dry with no fluid leaks from seals or torn boots?
- Free play within limit - under 2 inches at steering wheel rim?
- No binding or catch points through full lock-to-lock sweep?
- Rack mounting bushings and clamps secure with no looseness?
- Inner and outer tie rod ends tight with no play and boots intact?
Steering Column and Intermediate Shaft

- Tilt and telescoping column locks secure?
- Steering returns to center naturally after cornering?
- Road test confirms steering is responsive, straight, and no abnormal noise?
Documentation and Customer Advisory
Document findings and advise on related services.
- Alignment recommended after any steering component replacement?
- PS fluid service recommended if discolored or overdue?
- Safety-critical defects documented with customer signature if repair declined?
- Steering inspection documented with EPS codes, play measurements, and fluid condition?
- Related suspension and alignment items identified and quoted to customer?
