steering and suspension - final exam
this exam consists of 25 questions. answer each question.
on a parallelogram steering system, which of these could cause an improper toe - out on turns setting?
mark (√) if the problem could cause this symptom, mark (x) if it could not.
a worn idler arm mount.
worn tie rods.
worn pivot points on the center link.
faulty steering gearbox.

Explanation:

To determine which problems cause improper toe - out on turns in a parallelogram steering system, we analyze each component:

1. A worn idler arm mount

• The idler arm mount is crucial for the stability of the steering linkage. When it is worn, the alignment of the steering components gets disrupted. This disruption can lead to changes in the toe - out on turns setting. So, a worn idler arm mount can cause improper toe - out on turns, and we mark it with (√).

2. Worn tie rods

• Tie rods are responsible for transmitting the steering input to the wheels. If they are worn, there will be play or misalignment in the steering linkage. This misalignment directly affects the toe - out on turns setting. Thus, worn tie rods can cause the problem, and we mark it with (√).

3. Worn pivot points on the center link

• The center link's pivot points allow for the proper movement of the steering linkage. When these pivot points are worn, the geometry of the steering system is altered. This alteration can result in an improper toe - out on turns setting. So, we mark this with (√).

4. Faulty steering gearbox

• The steering gearbox is the component that converts the rotational input from the steering wheel into the linear or angular motion for the steering linkage. A faulty steering gearbox can cause incorrect steering ratios or misalignment in the steering system. This, in turn, can lead to an improper toe - out on turns setting. So, we mark it with (√).

Final Answers for Each Option:

• A worn idler arm mount: √
• Worn tie rods: √
• Worn pivot points on the center link: √
• Faulty steering gearbox: √
