Why is a broken leaf in a leaf spring suspension a defect that must be repaired before driving?
- A.It only affects ride comfort, not safety
- B.It makes the vehicle sit higher on one side
- C.It matters only when the truck is fully loaded
- D.A missing or broken spring can shift the axle and change steering and braking behavior
Correct answer
D. A missing or broken spring can shift the axle and change steering and braking behavior
Why
Springs carry the weight of the vehicle and keep axles in position. A broken spring can let the axle move, hurting alignment and stability, so it is an out-of-service type defect rather than a cosmetic one.
