Yeah I am trying to learn and differentiate the difference between components that wear out because of use versus the components that wear out with age (regardless of use). I am not a mechanic I do work around mechanics though but not really a wrench turning but I can do some diagnosis myself with research.
At what point in miles would the steering and braking components need replacing. I figure those components wear out with use so what is a normal life of them (in miles).
I figured the tires, hoses, and batteries will need a thorough looking at. These item deteriorate not only with use but also age. I know car tires aren't recommended to keep beyond 5-7 years what about commercial tires?
What are the weak points if any on the 8.3L and the Allison?
