Symptom Chart: NVH

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).

NVH symptoms should be identified using the diagnostic tools that are available. For a list of these tools, an explanation of their uses and a glossary of common terms, Glossary of Terms
REFER to: Noise, Vibration and Harshness (NVH) (100-04 Noise, Vibration and Harshness, Diagnosis and Testing).
Since it is possible any one of multiple systems may be the cause of a symptom, it may be necessary to use a process of elimination type of diagnostic approach to pinpoint the responsible system. If this is not the causal system for the symptom, REFER to: Noise, Vibration and Harshness (NVH) (100-04 Noise, Vibration and Harshness, Diagnosis and Testing).

Pinpoint Tests

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).


PINPOINT TEST A : VEHICLE DRIFTS, PULLS

Possible Sources

  • Unevenly loaded vehicle
  • Tire pressure
  • Tire forces
  • Brake drag
  • Incorrect vehicle alignment
  • Bent/damaged vehicle components
  • Steering system
A1 CHECK FOR UNEVENLY LOADED VEHICLE
  • Visually check the vehicle for an uneven loading condition.

Is the vehicle unevenly loaded?
Yes ADVISE the customer of uneven loading condition.
No GO to A2

A2 CHECK THE TIRE PRESSURES AND TIRE CONDITIONS
  • Check the tire pressures. Vehicle Certification (VC) Codes
    REFER to: Identification Codes (100-01 Identification Codes, Description and Operation).

Are the tire pressures and tire conditions OK?
Yes GO to A3
No ADJUST the tire pressures to the specified pressure or INSTALL new tires as necessary.

A3 ISOLATE TIRE DRIFT/PULL CONDITION
  • Cross the front wheel and tire assemblies from left-to-right.

Does the vehicle drift/pull?
Yes If the vehicle drifts/pulls in the opposite direction, tire forces are causing the drift/pull. ROTATE the wheel and tire assemblies front-to-rear. If the vehicle drifts/pulls in the same direction, GO to A4
No Tire forces were causing the drift/pull and the concern has been corrected.

A4 CHECK FOR BRAKE DRAG
  • Spin all four wheel and tire assemblies by hand and check for brake drag.

Do the wheels spin freely?
Yes GO to A6
No
REFER to: Suspension System (204-00 Suspension System - General Information, Diagnosis and Testing).

Component Tests

Ball Joint Inspection

  1. Prior to inspecting the ball joints for wear, inspect the wheel bearings and wheel hubs.
    REFER to: Noise, Vibration and Harshness (NVH) (100-04 Noise, Vibration and Harshness, Diagnosis and Testing).

  1. NOTE: In order to obtain accurate measurements, the suspension must be in full rebound with the weight of the vehicle supported by the frame.

    Raise and support the vehicle by the frame to allow the wheels to hang in the rebound position.
  1. Inspect the ball joint and ball joint boot for damage.
    • If the ball joint or ball joint boot is damaged, install a new lower ball joint as necessary.
      REFER to: Front Lower Arm (204-01A Front Suspension - RWD, Removal and Installation).
      REFER to: Front Lower Arm (204-01B Front Suspension - AWD, Removal and Installation).
      vehicles.

NOTE: Carry out Steps 4 through 6 to inspect the lower ball joint. Carry out Steps 7 through 9 to inspect the upper ball joint.

  1. NOTICE: Do not use any tools or equipment to move the wheel and tire assembly or suspension components while checking for relative movement. Suspension damage may occur. The use of tools or equipment will also create relative movement that may not exist when using hand force. Relative movement must be measured using hand force only.

    NOTE: The weight of the wheel and tire assembly must be overcome to obtain an accurate measurement on the dial indicator.

    Inspect the ball joint for relative movement by alternately pulling downward and pushing upward on the lower control arm by hand. Note any relative vertical movement between the wheel knuckle and lower control arm at the lower ball joint.
    • If relative movement is not felt or seen, the ball joint is OK. Do not install a new lower ball joint.
    • If relative movement is found, continue with Step 5.

  1. NOTE: In order to obtain an accurate measurement, the dial indicator should be aligned as close as possible with the vertical axis (center line) of the ball joint.

    To measure ball joint deflection, attach a suitable dial indicator with a flexible arm between the lower control arm and the wheel knuckle or ball joint stud.
  1. Measure the ball joint deflection while an assistant pushes up and pulls down on the lower control arm, by hand.
    • If the deflection exceeds the specification, a new lower ball joint must be installed.
      REFER to: Front Lower Arm (204-01A Front Suspension - RWD, Removal and Installation).
      REFER to: Front Lower Arm (204-01B Front Suspension - AWD, Removal and Installation).
      vehicles.
    • If the deflection meets the specification, continue with the procedure.

  1. NOTICE: Do not use any tools or equipment to move the wheel and tire assembly or suspension components while checking for relative movement. Suspension damage may occur. The use of tools or equipment will also create relative movement that may not exist when using hand force. Relative movement must be measured using hand force only.

    Inspect the ball joint for relative movement by alternately pulling downward and pushing upward on the upper control arm by hand. Note any relative vertical movement between the wheel knuckle and upper arm at the upper ball joint.
    • If relative movement is not felt or seen, the ball joint is OK. Do not install a new ball joint.
    • If relative movement is found, continue with Step 8

  1. NOTE: In order to obtain an accurate measurement, the dial indicator should be aligned as close as possible with the vertical axis (center line) of the ball joint.

    To measure ball joint deflection, attach a suitable dial indicator with a flexible arm between the upper control arm and the wheel knuckle or ball joint stud.
  1. Measure the ball joint deflection while an assistant pushes up and then pulls down on the upper control arm, by hand.
    • If the deflection exceeds the specification, a new upper arm must be installed.
      REFER to: Upper Arm (204-01A Front Suspension - RWD, Removal and Installation).
      REFER to: Upper Arm (204-01B Front Suspension - AWD, Removal and Installation).
