If the upper ball joint is positioned behind the lower ball joint, which of these describes the alignment condition?
Technician A says the tire wear pattern in the above illustration can result from incorrect toe settings. Technician B says the tire wear pattern can result from over inflation. Who is correct?
A vehicle equipped with struts and no provision for caster adjustments is out-of-spec on caster. Technician A says that a worn upper strut mount may be the cause. Technician B says that the caster angle may be able to be corrected by filling the strut mounting bolt holes and moving the location of the strut. Who is correct?
Both A & B
While setting the toe on a vehicle: Technician A centers and locks the steering wheel in place, then adjusts the toe to specifications. Technician B rotates an adjuster sleeve until the toe setting is correct. Who is correct?
Which of these correctly states when a power steering system should be bled?
When the fluid becomes aerated
While diagnosing a vehicle that has a tendency to bump steer, which of these should be checked first?
Technician A says the tires will wear prematurely if the vehicle's coil springs are weak or collapsed. Technician B says the alignment and steering angles will be affected if the vehicles coil springs are weak or collapsed. Who is correct?
Both A & B
Technician A says that while installing a front coil sprint, the insulator should be placed on top of the spring before the spring is placed into its lower seat. Technician B says that the end of the top coil should be lined up with the recess in the spring seat. Who is correct?
Both A & B
Which of these is NOT part of the normal procedure for replacing a front stabilizer bar?
