Steve's Four Wheel Alignment is a study course book on automobile wheel alignment. Steve talks and demonstrates how to diagnosis, and correct wheel misalignments. The quiz below gauges your understanding of the subject.

Questions and Answers
• 1.

### What is the most important alignment angle in terms of tire wear?

• A.

Camber

• B.

Caster

• C.

Toe

• D.

Steering axis inclination

Correct Answer
C. Toe
Explanation
Toe is the most important alignment angle in terms of tire wear. Toe refers to the angle at which the tires point inward or outward when viewed from above. Improper toe alignment can cause excessive tire wear, as it can lead to the tires scrubbing against the road surface. If the toe is misaligned, the tires will wear unevenly and prematurely, reducing their lifespan and performance. Therefore, maintaining proper toe alignment is crucial for optimal tire wear and longevity.

### When performing a four wheel alignment, always start by:

• A.

Checking the tire pressure of all four tires

• B.

Checking the pressure and condition of the tires on the rear axle

• C.

Rotating all four tires

• D.

All of the above

• E.

A and C only

Correct Answer
A. Checking the tire pressure of all four tires
Explanation
When performing a four-wheel alignment, it is important to start by checking the tire pressure of all four tires. This is because proper tire pressure is crucial for accurate alignment measurements and adjustments. If the tire pressure is not correct, it can affect the alignment readings and lead to inaccurate adjustments. Therefore, checking the tire pressure of all four tires is an essential step in the alignment process.

### Caster adds directional stability to a vehicle. Too much positive caster can cause:

• A.

Loose steering

• B.

A squealing noise around turns

• C.

Quick braking action

• D.

Hard steering

Correct Answer
D. Hard steering
Explanation
Positive caster refers to the angle at which the steering axis is tilted towards the rear of the vehicle. It helps to improve directional stability by ensuring that the wheels return to the straight-ahead position after a turn. However, if there is too much positive caster, it can cause the steering to become harder to turn. This is because the increased angle creates more resistance when trying to turn the wheels, resulting in a stiffer steering feel. Therefore, the correct answer is hard steering.

### It is important to regularly rotate tires. Which of the below choices is correct:

• A.

Tires should be rotated ecery 5,000 - 7,000 miles

• B.

If a vehicle both radial and bias tires, rotate them front to back only

• C.

After rotation a temporary noise problem will develop, but it will go away when the tire pattern returns to normal

• D.

If a vehicle has both radial and bias tires, rotate them in an "x" pattern only

Correct Answer
A. Tires should be rotated ecery 5,000 - 7,000 miles
Explanation
Regularly rotating tires is important to ensure even wear and extend their lifespan. The correct answer states that tires should be rotated every 5,000 - 7,000 miles. This is a recommended mileage range by experts to prevent uneven wear on tires. By rotating the tires at this interval, the wear pattern is distributed evenly across all tires, resulting in better traction, improved fuel efficiency, and longer tire life.

### A vehicle's steering parts are wearing out prematurely. A likely cause is:

• A.

Incorrect camber

• B.

Incorrect caster

• C.

Incorrect toe

• D.

All of the above

• E.

B and C only

Correct Answer
D. All of the above
Explanation
The correct answer is "all of the above." This means that all three options - incorrect camber, incorrect caster, and incorrect toe - are likely causes for the premature wearing out of a vehicle's steering parts. Each of these factors can affect the alignment and stability of the vehicle's wheels, leading to uneven tire wear and increased strain on the steering components. Therefore, it is important to ensure that all three aspects of the vehicle's steering system are properly adjusted and aligned to prevent premature wear and damage.

Rate this question:

• 6.

### Toe-out is:

• A.

Means the front of the tires are closer together than the rear of the tires

• B.

Means the front of the tires are farther apart than the rear of the tires

• C.

Corrects the tendency of the wheels to deflect out while in motion

• D.

Isn't affected when suspension height is changed

Correct Answer
B. Means the front of the tires are farther apart than the rear of the tires
• 7.

### Benefits of a four wheel alignment include:

• A.

Increased tire life

• B.

Increased fuel economy, if driving habits remain the same

• C.

Increased turning angle

• D.

All of the above

• E.

A and B only

Correct Answer
E. A and B only
Explanation
A four-wheel alignment has the benefits of increased tire life and increased fuel economy, if driving habits remain the same. By aligning all four wheels properly, it ensures that the tires wear evenly, reducing the risk of premature wear and extending their lifespan. Additionally, a properly aligned vehicle experiences less rolling resistance, which can lead to improved fuel efficiency. Therefore, the correct answer is A and B only.

### The tires on a motor home have an abnormal wear pattern. All you can suggest to your customer is :

• A.

Adjust positive camber

• B.

Buy new, bigger radial tires

• C.

Keep tires properly inflated, rotate them on schedule, and check the alignment

• D.

Replace the tie rods

Correct Answer
C. Keep tires properly inflated, rotate them on schedule, and check the alignment
Explanation
The correct answer is to keep the tires properly inflated, rotate them on schedule, and check the alignment. This is because abnormal wear patterns on the tires can be caused by various factors such as underinflation, lack of rotation, and misalignment. By ensuring that the tires are properly inflated, regularly rotated, and the alignment is checked, the customer can prevent further abnormal wear and extend the lifespan of their tires. Adjusting positive camber, buying new, bigger radial tires, or replacing tie rods may not address the underlying causes of the abnormal wear pattern.

### On most vehicles, _____ should be adjusted first:

• A.

Camber

• B.

Caster

• C.

Toe

• D.

It doesn't matter which order, unless its a front wheel drive car

Correct Answer
A. Camber
Explanation
Camber should be adjusted first on most vehicles because it refers to the angle of the wheels in relation to the vertical axis when viewed from the front or rear of the vehicle. Proper camber adjustment ensures that the wheels are perpendicular to the road surface, which helps with tire wear and stability while driving. Adjusting camber before other factors such as caster and toe is important to establish a solid foundation for the overall alignment of the vehicle.

### A vehicle's tires show excessive tire wear to one side of the tire tread. A possible cause is:

• A.

A worn steering knuckle

• B.

Incorrect caster

• C.

Incorrect camber

• D.

Improper inflated tires

Correct Answer
C. Incorrect camber
Explanation
Incorrect camber refers to the angle of the tire in relation to the road surface. When the camber is not set correctly, the tire will tilt either inward or outward. This can result in excessive tire wear on one side of the tire tread.
