A spacer or clamp on a dual wheel assembly is found loose and the wheels have visible movement. What is the danger if you drive on?
- A.The wheels can work completely loose and come off the hub, becoming a lethal hazard to other road users
- B.Loose spacers improve fuel economy
- C.Only the hubcap is at risk
- D.The movement tightens itself at highway speed
Correct answer
A. The wheels can work completely loose and come off the hub, becoming a lethal hazard to other road users
Why
A wheel that leaves a truck at speed carries the energy of a small car and has killed people in other vehicles. Any looseness in the mounting system means the assembly comes apart in the shop now, on purpose, instead of on the road later.
