Is the vibration still present?
Measuring Wheel Alignment
Steering and vibration complaints are not always the
result of improper alignment. One possible cause is
wheel and tire imbalance. Another possibility is tire lead
due to worn or improperly manufactured tires. Lead/pull
is defined as follows: At a constant highway speed on a
typical straight road, lead/pull is the amount of effort
required at the steering wheel to maintain the vehicle's
straight path. Lead is the vehicle deviation from a
straight path on a level road without pressure on the
steering wheel. Refer to "Radial Tire Lead/Pull
Correction: " in order to determine if the vehicle has a tire
lead problem.
Before performing any adjustment affecting wheel
alignment, perform the following inspections and
adjustments in order to ensure correct alignment
readings:
• Inspect the tires for the proper inflation and irregular
tire wear. Refer to "Vehicle Certification, Tire Placard,
Anti-Theft, and Service Parts ID Label: " and "Tire
Diagnosis - Irregular or Premature Wear: ".
• Inspect the runout of the wheels and the tires. Refer to
"Tire and Wheel Runout Specifications: ".
• Inspect the wheel bearings for backlash and
excessive play. Refer to "Wheel Bearings Diagnosis:
".
• Inspect the ball joints and tie rod ends for looseness
or wear.
• Inspect the control arms and stabilizer shaft for
looseness or wear.
• Inspect the steering gear for looseness at the frame.
Refer to "Fastener Tightening Specifications - Power
Steering System: ".
• Inspect the struts/shock absorbers for wear, leaks,
and any noticeable noises. Refer to "Suspension Strut
and Shock Absorber Testing - On Vehicle: ".
• Inspect the vehicle trim height. Refer to "Trim Height
Inspection: ".
• Inspect the steering wheel for excessive drag or poor
return due to stiff or rusted linkage or suspension
components.
• Inspect the fuel level. The fuel tank should be full or
the vehicle should have a compensating load added.

Give consideration to excess loads, such as tool boxes,
sample cases, etc. If normally carried in the vehicle,
these items should remain in the vehicle during
alignment adjustments. Give consideration also to the
condition of the equipment being used for the alignment.
Follow the equipment manufacturer's instructions.
Satisfactory vehicle operation may occur over a wide
range of alignment settings. However, if the setting
exceeds the service allowable specifications, correct the
alignment to the service preferred specifications. Refer
to "Wheel Alignment Specifications: ".
Perform the following steps in order to measure the front
and rear alignment angles:
1. Install the alignment equipment according to the
manufacturer's instructions.
2. Jounce the front and the rear bumpers 3 times prior
to checking the wheel alignment.
3. Measure the alignment angles and record the
readings.
NOTE
When performing adjustments to vehicles
requiring a 4-wheel alignment, set the rear
wheel alignment angles first in order to
obtain proper front alignment angles.
4. Adjust alignment angles to vehicle specification, if
necessary. Refer to "Wheel Alignment
Specifications: ".
