A technician is performing a pre-purchase inspection on a used vehicle. They notice excessive play in the steering wheel and a clunking noise when turning the wheel at low speeds. Which of the following components is MOST likely worn?
- ABrake pads
- BShock absorbers
- CTie rod ends
- DWheel bearings
Show answer & explanationAnswer & explanation
Correct answer: C. Tie rod ends
Excessive play in the steering wheel and a clunking noise during turns are classic symptoms of worn tie rod ends. These components connect the steering rack to the steering knuckle, and their wear directly affects steering precision and can cause noise.
Why the other options are wrong
- A. Worn brake pads cause grinding or squealing during braking, not steering play or clunking during turns.
- B. Worn shock absorbers primarily affect ride comfort and handling over bumps, not steering play or clunking during turns.
- D. Worn wheel bearings typically cause a growling or humming noise that changes with vehicle speed, not usually excessive steering play or clunking during turns.
Worn Tie Rod Ends
Degradation of the ball-and-socket joint connecting the steering rack to the steering knuckle, leading to loose steering and potential noise.
- Causes excessive play or looseness in the steering wheel.
- Can produce clunking or popping noises, especially when turning or going over bumps.
- Affects wheel alignment and tire wear.
Memory trick: Loose 'TIE' rods make the steering 'WOBBLE' and 'CLUNK'.
