| 7. Loose inner tie rod. | 7. For evaluation and correction. Refer to END, TIE ROD, DIAGNOSIS AND TESTING . | |
| 8. Loose lower control arm mounting bolts at engine cradle, frame or crossmember (occurs with steering input only when moving, not stationary). | 8. Check control arm mounting bolts and tighten to specified torque. | |
| 9. Loose intermediate shaft or column. | 9. Rotate intermediate (steering) shaft in relationship to gear, checking for free-play. Check column fasteners and tighten to specifications as necessary. | |
| 10. Lower control arm pivot bushing worn (occurs with steering input only when moving, not stationary). | 10. Inspect bushings for wear and replace lower control arm as necessary. | |
| 11. Internal power steering gear noise. | 11. Drive vehicle on rough road, then steer rapidly back and forth when stopped. Replace power steering gear as necessary. | |
| 12. Stabilizer bar link joints worn (occurs with steering input only when moving, not stationary). | 12. At park, jounce only one side of vehicle front to exercise stabilizer bar. Replace stabilizer bar link. | |
| 13. Excessive play in outer tie rod. | 13. For evaluation and correction. Refer to END, TIE ROD, DIAGNOSIS AND TESTING . | |
| POPPING NOISE | 1. Loose steering gear mounting fasteners. | 1. Check fasteners for proper torque specification and retighten as necessary. |
| 2. Loose outer tie rod mounting nut or jam nut. | 2. Check fastener torque. Replace nuts as necessary and tighten to specifications. | |
| 3. Loose intermediate (steering) shaft coupling at gear input shaft. | 3. Make sure coupling is fully seated on gear input shaft. Retighten or re-seat as necessary. | |
| 4. Worn tie rod (outer or inner). | 4. For evaluation and correction. Refer to END, TIE ROD, DIAGNOSIS AND TESTING . | |
| 5. Worn axle shaft. | 5. For evaluation and correction refer to the diagnosis and testing information for the appropriate front axle. | |
| CHIRP OR SQUEAL (POWER STEERING PUMP) | 1. Loose power steering pump drive belt. | 1. Inspect belt. Replace belt if worn or glazed. Tighten/adjust power steering pump drive belt if equipped with a manual tensioner. |
| 2. Pulley alignment incorrect. | 2. Realign accessory drives. | |
| 3. Malfunctioning belt auto tensioner | 3. Verify belt tension. Replace belt auto tensioner. | |
| 4. Power steering pump noisy (worn bearing/bushing noise). | 4. Using an electronic listening tool, determine if noise is coming from pump. Replace power steering pump as required. | |
| 5. Generator or water pump noisy. | 5. Using an electronic listening tool, determine if noise is coming from Generator or water pump. Replace faulty component. | |
| WHINE, GROWL, MOAN OR GROAN (POWER STEERING PUMP)*** | 1. Low power steering fluid level. | 1. Fill power steering fluid reservoir to proper level and check for leaks (make sure all air is bled from the system fluid). |
| 2. Air in power steering fluid. | 2. Inspect for excessive air bubbles in fluid (fluid will appear foamy and lighter in color). Inspect hoses for leaks and replace as necessary. Bleed air from fluid Refer to : POWER STEERING SYSTEM BLEEDING . | |
| 3. Power steering hose touching body or frame of vehicle. | 3. For evaluation and correction. Refer to PUMP, DIAGNOSIS AND TESTING . | |
| 4. Wear of power steering pump internal components. | 4. For evaluation and correction. Refer to PUMP, DIAGNOSIS AND TESTING . | |
| COLD START WHINE OR MOAN (POWER STEERING PUMP)*** | 1. Low power steering fluid level. | 1. Fill power steering fluid reservoir to proper level and check for leaks (make sure all air is bled from the system fluid). |
| 2. Extremely low ambient temperature (near 0 F° (-18 C°) or below) | 2. Some noise is expected as pump attempts to pull cold, thick fluid. Noise should go away as vehicle warms up. Acceptable levels of excessive noise are one second at 0 F° (-18 C°) and 15 seconds at -20 F° (-29 C°). If noise is excessive, look for poor sealing on the return hose or a possible fluid leak. | |
| SQUEAKING OR RUBBING SOUND | 1. Steering column shroud or shaft rubbing. | 1. While turning the steering wheel, listen down column to locate. Check interference between moving components. Move or realign shrouds or shaft as necessary. Replace components if this does not correct problem. |
| 2. Clockspring inside steering column noisy. | 2. Remove clockspring and reinstall steering wheel for testing. If noise is gone, replace clockspring. | |
| 3. Boot/dash seal lubrication inadequate. | 3. Remove boot seal and recheck for noise. Lubricate seal as necessary. | |
| 4. Steering gear outer tie rod noisy. | 4. While a helper turns the steering wheel, use an electronic listening tool to determine if noise is coming from either outer tie rod. Replace outer tie rods as necessary. | |
| 5. Steering gear internally noisy. | 5. Remove dash seal boot, then exercise the steering wheel. If noise is still present at gear, replace steering gear. | |
| SCRUBBING OR KNOCKING SOUND. | 1. Incorrect tire or wheel size. | 1. Replace incorrect size tire or wheel with original equipment size. |
| 2. Worn motor or transmission mount. | 2. Drive vehicle, moving accelerator pedal rapidly up and down attempting to locate noise. Try in both forward and reverse. Replace mounts as necessary. | |
| 3. Tires contacting wheel well. | 3. Make sure wheel house is properly positioned. If not, reposition as necessary. If steering wheel is properly centered, check steering gear travel left to right by rotating the steering wheel to each stop. Steering wheel should rotate the same amount in both directions from center. If not, replace steering gear. | |
| 4. Interference between moving steering components and other components. | 4. Check for bent or misaligned components. Correct or replace as necessary. | |
| 5. Accessory drive pulley rubbing against another component. | 5. Check pulleys for wear. Check for worn engine or transmission mount. Reposition components or replace mounts as necessary. |
NOTE:
* There is some noise in all power steering systems. One of the most common is a hissing sound evident when turning the steering wheel when at a standstill or when parking and the steering wheel is at the end of its travel. Hiss is a very high frequency noise similar to that experienced while slowly closing a water tap. The noise is present in every valve and results when high velocity fluid passes valve orifice edges. There is no relationship between this noise and the performance of the steering system.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
