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:
A) Worn-out shock absorbers
B) A weak stabilizer bar
C) Sagged coil springs
D) Center link that is not level

Question

Quizplus · Accepted Answer

A parallelogram steering linkage requires that the center link be level for proper steering alignment. If the center link is not level, it can cause the sudden veering of the steering wheel when one of the front wheels strikes a road irregularity. Worn-out shock absorbers, a weak stabilizer bar, and sagged coil springs can cause other steering and suspension issues, but are not the most likely cause of this specific problem.
