Technician A says excessive toe-out (negative) on a front wheel causes rapid wear on the inside edge of the tire tread. Technician B says excessive positive camber on a front wheel causes premature wear on the outside edge of the tire tread. Who is correct?
Technician Asays on many rear-wheel drive cars, the front wheels are set to a slight toe-in position. Technician B says the driving forces on a rear-wheel drive car tend to move the front wheels to a toe-in position. Who is correct?
During a road test on a front-wheel drive vehicle, it is determined that the vehicle pulls right after a right turn, and pulls left after a left turn. The most likely cause of this condition is:
Technician A says if a front wheel has positive camber, the camber line is at the true vertical centerline of the tire and wheel. Technician B says if the left-front wheel has excessive positive camber and the right-front wheel camber is correct, the steering pulls to the left. Who is correct?
Technician A says if the front wheels have a toe-out condition, the distance between the front edges of the tires is greater than the distance between the rear edges of the tires. Technician B says many front-wheel drive cars have a slight toe-out setting because driving forces tend to move the front wheels to a toe-in position. Who is correct?
When one of the front wheels strikes a road irregularity, the steering suddenly veers to the right or left on a vehicle with a parallelogram steering linkage. The most likely cause of this problem is:
Technician A says excessive positive caster may cause front wheel shimmy. Technician B says excessive positive caster increases steering effort and causes harsh riding. Who is correct?
Technician A says a jack-and-hold feature on some computer wheel aligners allows the technician to lift one side of the suspension with a jack while maintaining accurate alignment readings on the screen. Technician B says when using a computer wheel aligner, the technician may print out any screen at any time. Who is correct?
Technician Asays front wheel toe should be measured with the front wheels in the straight-ahead position. Technician B says excessive front wheel toe-in causes steering pull to the right. Who is correct?
Technician A says a tire pressure check is not required before a wheel alignment. Technician B says a front wheel bearing play should be checked before a wheel alignment. Who is correct?
Technician A says incorrect wheel alignment angles will reduce tire tread life. Technician B says wheel alignment is necessary after ball joint replacement. Who is correct?
