2007 Ford Explorer Sport Trac Question: can a rear carrier bearing be detected as going bad before it goes bad?
Depends on the experience of the tech. Sometimes it's not as obvious. So the answer is Yes and No. - ProfessorG
The simple anwser is no unless a noise was evident on a road test. When a bearing fails it can fail rapidly. - milesauto
