Pinpoint Test Ac-2: Noise - Turning At Slow Speeds Or During Parking Lot Maneuvers
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation and Fault Conditions
Description
- Exterior front end noises when turning at slow speeds involve parts which move, rotate or make contact during a partial or full turn. Please note whether the vehicle has column mounted EPAS, steering gear mounted EPAS, or adaptive steering.
Pinpoint Test Applicability
- This test applies to the following diagnostic concerns:
- Noises occurring at slow speeds or during parking lot maneuvers
This test DOES NOT apply to any other DTC or symptom.
Diagnostic Strategy
- To visually check for obvious parts that may be damaged within parts that are in motion during this drive event, followed up by Chassis Ears usage to further define where the noise source may be while steering (turning the steering wheel) during this drive event.
Pinpoint Test Purpose
- To search for the components contributing to steering noises during this drive event and determine if the resulting components are defective or the noise is a normally occurring noise for this vehicle type.
Possible Sources
- Springs, shocks, struts and bearings or bushings (most common)
- Tires
- Steering gear internal stops (full turn)
- External steering stops (full turn)
- Steering tie rods (loose)
- Loose steering gear mounts or bolts
- Stabilizer bar insulators or links
- Integrated front wheel ends (4x4 only)
- Front control arms and bushings
- Front halfshaft and bearings (ting or ping metallic noise at slow speeds) (if equipped)
- Subframe or crossmember condition, mounts or fasteners
- Engine or transmission mounts
