Badeye, good idea. Mine are as follows:
Cat. 3126
Allison
22,000 miles
Alternator needle started going "down"
After awhile, engine was running, but shifting was getting erratic
Cause was a failing Leece Neville alternator
Freightliner dealer in Waco Tx. got us in immediately, diagnosed the problem, & ordered the new alternator. It came air freight, & we were on our way late the next day. Freightliner & Leece Neville declined to cover cost as "it is out of warranty".It was because of the age, by about 4 months, but still only 22,000 miles.
My second was the familiar "zipper" blow out on the Michelin tire. It happened on an interstate, cool temps, not even close to overload, at about 25,000 miles.
