Question 2

If the steering wheel is not straight ahead when driving, what procedure would you use to straighten it?

Accepted Answer

Follow these steps to correctly straighten the steering wheel: 
- Carefully count the number of turns of the steering wheel while turning it from lock to lock. The total can include fractions of a turn, so pay careful attention when counting. 
- When you have determined the distance between the locks, position the steering wheel so it is halfway between them. It should be straight. If not, remove it and put it back in the correct position.

D)  setback 
A)  toe change 
B)  wheelbase difference 
C)  thrust angle 
D)  setback

Question 12

Front wheel bearings on rear-wheel-drive vehicles do not wear out very often. However, bearing misalignment can be caused by a bent spindle; this increases the load on the bearing.

Accepted Answer

A) True 
 B)False

Question 13

All of the following statements are true EXCEPT:

Accepted Answer

A)  on the rear of a vehicle, toe equalizes between the two tires like it does on the front. 
B)  on radial tires on RWD vehicles with toe-in, the right front tire tends to toe in more than the left; its outside edge wears because the tire is rolling under at that edge. 
C)  radial tires on RWD vehicles with toe-in will both roll under, resulting in wear that looks like positive camber. 
D)  with toe-out, the inside edge of the left tire will roll under, resulting in wear on the inside edge of the left front tire. 
A)  on the rear of a vehicle, toe equalizes between the two tires like it does on the front. 
B)  on radial tires on RWD vehicles with toe-in, the right front tire tends to toe in more than the left; its outside edge wears because the tire is rolling under at that edge. 
C)  radial tires on RWD vehicles with toe-in will both roll under, resulting in wear that looks like positive camber. 
D)  with toe-out, the inside edge of the left tire will roll under, resulting in wear on the inside edge of the left front tire.

Question 16

Which of the following statements is LEAST-Likely true?

Accepted Answer

A)  If tires are to be replaced, the new tires should be installed before attempting an alignment. 
B)  When correcting for road crown, camber creates less of a pull than caster. 
C)  Caster causes the camber angle of the wheel to change during a turn. 
D)  Roads are crowned (higher at the center than the outside) so that rain will run off.

All of the following statements are true EXCEPT:

Accepted Answer

A)  when a rack-and-pinion steering gear is mounted out of level position, its tie-rods will be at equal angles. 
B)  aftermarket suspension parts sometimes relocate steering linkage connections, which can cause extreme toe change when the suspension moves. 
C)  the toe setting on a tire can change when the wheel goes into a pothole or over a bump. 
D)  turning radius is not an adjustable angle, but if a steering arm becomes bent, the turning radius is affected and the tires can squeal on turns.
