Noise
| Symptom | Possible Causes | Action |
|---|---|---|
| Continuous noise | Low power steering fluid level | Check for leaks and rectify as required. For further information refer to the symptom charts for leakage in this section. Fill power steering fluid reservoir to correct level |
| NOTE: Look for small air bubbles visible in the fluid, air may also get trapped in the hydraulic system Air in hydraulic system | Bleed the power steering system. Refer to: Power Steering System Bleeding . | |
| Power steering pipe/hose in contact with the vehicle body | Check and reposition, or install new IF damaged/deformed, power steering pipe/hose | |
| Power steering pipe/hose restricted or twisted | Check and clear restriction to pipe/hose Reposition power steering pipe/hose. Install new pipe/hose IF permanently damaged/deformed | |
| Power steering pump mounting bolts loose | Tighten the power steering pump mounting bolts to the correct torque. Refer to: Specifications . | |
| Noise gets worse when system is loaded | NOTE: Refer to the power steering pressure check in this section Low power steering fluid level Aerated fluid Low power steering pump pressure | Check and fill power steering fluid reservoir to correct level Bleed the power steering system. Refer to: Power Steering System Bleeding . Check power steering pump pressure. If the pump pressure is low, install a new power steering pump |
| Front End Accessory Drive (FEAD) belt squeal | FEAD belt incorrectly tensioned or glazed | Check FEAD belt tension Check FEAD belt condition and install a new belt as required |
| Chirp noise from the steering pump when a load is applied | Loose or worn FEAD belt | Check FEAD belt tension Check FEAD belt condition and install a new belt as required |
| Scrape/grind noise from behind steering wheel while steering | Steering column shroud foul condition or clockspring | Correctly install the steering column shroud to eliminate the foul condition Install a new clockspring as required |
| Foreign objects | Remove foreign objects from between steering column shroud and steering wheel/steering column rotating components | |
| Click | Clockspring or steering column multifunction switch LH | Correctly install and install new components as required |
| Loose universal joint pinch bolt | Install a new universal joint pinch bolt and tighten to correct specification. Refer to: Specifications . | |
| Squeak | Steering column shroud joints | Apply Krytox spray to steering column shroud joints |
| Clockspring | Install new clockspring as required | |
| Knock | Loose fixings (universal joint pinch bolt and steering column fixings) | Tighten fixings to correct specification. Refer to: Specifications . |
| Rattle | Foreign objects | Remove foreign objects from between steering column shroud and steering wheel/steering column rotating components |
| Loose fixings | Tighten steering column fixings to correct specification. Refer to: Specifications . | |
| Noise while adjusting column | Electric motor/solenoid | NOTE: Before carrying out repairs/replacement, assess column adjustment noise levels against other vehicles of the same model Install new components as required |
| Motor spindle/lead screw | Lubricate lead screw |

Vibration
| Symptom | Possible Causes | Action |
|---|---|---|
| Wheel Fight (Kick Back) - condition where roughness is felt in the steering wheel by the driver when the vehicle is driven over rough surfaces | Loose or worn steering components/bushings | CAUTION: DO NOT attempt to adjust the steering gear yoke. Failure to follow this instruction will invalidate the steering gear warranty. Tighten and install new steering components/bushings as required |
| Loose or worn suspension components/bushings | Tighten and install new suspension components/bushings as required | |
| Nibble (Shimmy) - condition where oscillation of the steering wheel occurs (not vertical which is Shake). This is driven by road wheel imbalance | Road wheel and tire condition | Check for wheel and tire damage. Install new components as required Check for tire uniformity. Install new tire(s) as required |
| Road wheel imbalance | Check and adjust road wheel balance as required | |
| Shake - condition where vertical vibration of the steering wheel/column occurs (not oscillation which is Nibble) | NOTE: Vibration smooths out after several miles of driving Road wheel imbalance due to tire flat-spotting | Ensure tires installed are to Jaguar specification. Install new tires as required Check and adjust tire pressures to correct specification |

Hum
Continuous sound of varying frequencies, like a wire humming in the wind.
Rattle
A sound suggesting looseness, such as marbles rolling around in a can.
Squeak
High-pitched sound like rubbing a clean window.
Column Rattle
Column rattle is a metallic sounding noise created when applying a highly impulsive force to the steering wheel. Column rattle is often used to combine the more general group of column noises including clonk and column knock. Column rattle noises can be caused by clonk, knock, loose column components, bonus parts etc. A series of parked, straight-line driving, and cornering tests should be carried out to isolate the source/sources.
Rattles
Rattles are noises caused by knocking or hitting of components in the steering system. Steering rattles can occur in the engine compartment, the suspension, or the passenger compartment. Rattles can be caused by loose components, movable and flexible components, and improper clearances.
Squeaks/Scrapes
Squeaks/Scrapes are noises due to friction or component rubbing anywhere in the steering system. Squeaks/Scrapes have appeared in steering linkages and joints, in column components and in column and steering wheel trim.
