Rationales 2026 Q&A | Instant Download Pdf
1. A vehicle exhibits uneven tire wear on the inside edges of both
front tires. Which is the most likely cause?
A. Worn shock absorbers
B. Excessive negative camber
C. Misaligned toe-in
D. Overinflated tires
Rationale: Excessive negative camber causes the top of the tire to tilt
inward, leading to accelerated inside edge wear.
2. Which component controls the rear wheel movement on a
MacPherson strut suspension?
A. Control arm
B. Strut assembly
C. Sway bar
D. Tie rod
,Rationale: In a MacPherson strut suspension, the strut assembly acts
as both a shock absorber and a structural component controlling
wheel movement.
3. A vehicle has a “loose” steering feel and excessive play. Which is
the most likely cause?
A. Worn tie rod ends
B. Worn steering gearbox
C. Low power steering fluid
D. Misaligned caster
Rationale: A worn steering gearbox can create significant play in the
steering wheel, resulting in a loose feel.
4. What is the primary purpose of a sway bar?
A. Increase tire grip
B. Reduce tire wear
C. Reduce body roll
D. Support vehicle weight
,Rationale: Sway bars, also called anti-roll bars, reduce body lean
during cornering by transferring force from one side of the suspension
to the other.
5. Which type of suspension uses upper and lower control arms of
unequal length?
A. MacPherson strut
B. Short-long arm (SLA) double wishbone
C. Torsion beam
D. Leaf spring
Rationale: SLA suspensions have unequal-length control arms to
improve camber control during wheel travel.
6. A vehicle pulls strongly to the left when driving straight. Which is
the first check recommended?
A. Worn shocks
B. Tire inflation and condition
C. Loose tie rod ends
D. Worn sway bar bushings
, Rationale: Uneven tire pressure or tire defects are the simplest and
most common causes of a vehicle pulling to one side.
7. Which component is most likely worn if a front-end clunk is heard
when going over bumps?
A. Sway bar
B. Ball joint
C. Control arm bushing
D. Tie rod end
Rationale: Worn control arm bushings allow movement between the
control arm and frame, producing a clunk over bumps.
8. When aligning the front suspension, which measurement controls
the steering wheel return to center?
A. Camber
B. Caster
C. Toe
D. SAI (Steering Axis Inclination)
Rationale: Positive caster provides self-centering of the steering wheel
and stability during straight-line driving.
