During a vehicle safety check, drivers must examine specific suspension parts for distinct signs of mechanical wear, looseness, or failure. Match each suspension component on the left with its corresponding critical inspection defect on the right.
- U-boltsRust trails or shiny metal rub marks around fastening nuts indicating loose axle clamping
- Shock absorberSevere fluid leakage actively dripping down the external cylindrical housing
- Torque rodDeteriorated rubber bushings or cracked arm structure that permits axle misalignment
- Leaf spring assemblyCracked, missing, or shifted metal strips that could move out of place and contact a tire
Answer
U-bolts match with rust trails or shiny metal rub marks around fastening nuts; Shock absorber matches with severe fluid leakage actively dripping down the housing; Torque rod matches with deteriorated rubber bushings or cracked arm structure; Leaf spring assembly matches with cracked, missing, or shifted metal strips.
Each suspension element exhibits distinctive failure signs: U-bolts exhibit rust streaks or polished metal when loose; shock absorbers fail by losing hydraulic fluid through blown seals; torque rods fail at their pivot bushings or weld seams leading to axle misalignment; and leaf springs fail through cracking, breaking, or leaf displacement.
