Diesel Tech Suspension and Steering ASE Exam Practice Test 6 Updated 2024/2025 Questions and Answers 100% Correct.

Steering wheel shimmy at high speeds may be caused by: A. Too much positive caster B. Out-of-balance wheel and tire assemblies C. Air in the steering system D. Low tire pressure - B. Out-of-balance wheel and tire assemblies Load distribution is being discussed. Technician A says that if the fifth wheel is too far ahead, more weight is transferred to the steer axle increasing steering effort. technician B says if the fifth wheel is too far rearward, not enough weight will be transferred to the steer axle causing steering instability. Who is correct? A. A only B. B only C. Both A and B D. Neither A nor b - C. Both A and B When checking the end-play measurement on a PreSet hub, the tip of the dial indicator should be placed on the hub cap flange or axle mounting flange, and the magnetic base of the dial indicator should be mounted on the hub's: A. Spindle end B. Hub cap C. Wheel hop or tramp D. Wheel shimmy - A. Spindle end An improperly adjusted air suspension ride height can cause: A. Damaging driveline angles B. A hissing noise during compressor operationC. Back pressure in the supply line D. A leak, causing intermittent operation - A. Damaging driveline angles What is the LEAST LIKELY advantage for the use of sliding fifth wheel assemblies on over-the-road equipment? A. Weight-over-axle on the tractor may be altered B. Weight-over-axle on the trailer may be altered C. The trailer bridge formula may be altered D. It allows for the use of a rigid-mount fifth wheel - D. It allows for the use of a rigid-mount fifth wheel All of the following conditions may cause steering wander or pull EXCEPT: A. Improper rear-axle alignment B. Loose steering gear C. Excessive positive caster D. Worn kingpin bushings - C. Excessive positive caster When adjusting front-wheel camber: A. If the front wheel has a positive camber angle, the camber line is tilted inward from the tire vertical centerline of the wheel and tire B. Excessive positive camber on a front wheel causes premature wear on the inside edge of the tire tread C. The vehicle will lead to the side that has the most negative camber D. If the camber angle is out of specification, this may be caused by worn suspension components - C. The vehicle will lead to the side that has the most negative camber Technician A says some abnormal tire wear conditions are normal for certain design tires. Technician B says the TMC Radial Tire conditions Analysis Guide or Manufacturers Tread Wear Reference Guide should be used to determine tire wear pattern conditions. Who is correct? A. A only B. B only C. Both A and BD. Neither A nor B - C. Both A and B What is the LEAST LIKELY condition that improper wheel balance would cause? A. Cupped tire tread wear B. Vibration while braking C. Wheel hop or tramp D. Wheel shimmy - B. Vibration while braking How should steering knuckle vertical clearance be adjusted? A. Adding or subtracting shims B. Selecting the correct draw key C. Using the appropriate bushings D. Adjusting a stop bolt and jam nut - A. Adding or subtracting shims
