The correct answer is A. If the vehicle is equipped with a limited slip differential, raise the opposite wheel to be safe. Otherwise, the vehicle could either damage the differential or drive itself over the wheel chocks and cause an accident. Technician B is wrong because when wheels have been spin-balanced on the axle, they must be rebalanced whenever the tires are rotated.
Technician A says that, when on-vehicle balancing a drive axle tire, the opposite wheel must also be supported off the ground if the vehicle is equipped with a limited-slip differential. Technician B says that rotating on-vehicle balanced tires presents no special problems. Who is correct? A. Technician A B Technician B C Both A and B D. Neither A or B
The correct answer is B. Since the right side has too much negative camber, this will cause the tire to tilt inwards at the top and cause the right tire to wear the inside shoulder of the tire more quickly. It is also likely that the left tire would wear on the outside shoulder due to too much positive camber.
The above alignment settings would result in which of the following conditions? A. Left tire wear on the inside. vehicle does not pull to either side. B. Right tire wear on the inside, vehicle pulls to the left C. Right tire wear on the outside, vehicle pulls to the left. D. Right tire wear on the outside. left tire wear on the inside and vehicle pulls to the left.
The correct answer is B. The wheel alignment should be checked after the ball joint (or any suspension part) is replaced. It is not necessary to install a coil spring compressor prior to separating the control arm and the spindle because the Macpherson strut assembly contains the spring. However, a spring compressor should be used if the strut is being disassembled.
The ball joints on the MacPherson strut-type suspension shown above are being replaced. Technician A says that a coil spring compressor should be installed before separating the control arm and the spindle. Technician B says that the wheel alignment should be checked after the ball joints have been replaced. Who is correct? A. Technician A B. Technician B C. Both A and B D. Neither A or B
The correct answer is B. If the thrust line is to the left and the steering wheel is held straight, the vehicle will veer to the right This happens because the rear wheels will travel towards the left, which will force the front of the vehicle to the right.

Too much caster on the left front wheel will cause the ....? A Vehicle to drift to the left B. Left tire to wear on the outside edge C. Vehicle to drift to the right D. Left tire to wear on the inside edge
The correct answer is B. A binding upper bearing or incorrectly installed TBS tie-rod-end would pull the steering to a specific point and stop regardless whether the engine was running or not. Since the engine needs to be running to have this condition occur, the power steering valve is causing the problem.
When a car is raised on a lift with the wheels pointed straight ahead and when the engine is started, the wheels slowly turn to the right. Technician A says that a binding upper bearing on a MacPherson strut or an improperly installed RBS tie-rod end could cause this condidon. Technician B says that power steering valve is out of adjustment. Who is correct? A. Technician A B. Technician B C. Both A and B D. Neither A or B
The correct answer is D. Either a bent Pitman arm or a tie-rod could cause the specification for toe-out on turns to be out of specification. Vehicles with non-symmetrical steering systems will have a difference from side-to-side, but the difference will not exceed manufacturer's specifications and it rarely has greater than 1.5 degrees difference from side-to-side.

Technician B says to rotate the tire and wheel assembly to attempt to bring the runout within specifications. Who is correct? A. Technician A B. Technician B C. Both A and B D. Neither A or B
The correct answer is B. Wile some McPherson strut assemblies do not allow camber or caster adjustments, many vehicles do have eccentrics or slotted mounting holes to provide adjustment. An abnormal change in camber normally indicates a bent strut,
When the suspension is worked up and down on a vehicle equipped with MacPherson strut-type suspension, the camber specification changes more on one side than the other. Technician A says that camber can't be adjusted on a MacPherson strut.. technician B says that the strut on the side that camber changes the most may be bent. Who is correct? A. Technician A B. Technician B C. Both A and B D. Neither A or B
The correct answer is D. If the ballstud has broken, it is possible that the tapered hole in the steering knuckle has become distorted. You can check this by trying the new ball joint stud in the hole; if there is any free-play or if the new tapered stud can rock in the hole, the hole is rounded out. If this has occurred, the steering knuckle must be replaced.
Which of the following causes for ball joint replacement would also require steering knuckle replacement? A. Torn dust cover B. Worn ball and socket C. Wear indicator below surface D. Broken ballstud
