Only 145K miles on our Dodge. Just getting warmed up. Here is what we replaced:
lift pump @ 92K mi.
brakes @ 76K and 141K
Batteries @ 98K and 140K (not many miles on the rig the last 6 yrs. The orig. Delco starting batts went 6 years)
No engine work. Orig. clutch, trans. and driveline. Orig. injector pump and injectors.
My neighbor bought a used '01 Dodge CTD and now has 366K miles on it and it is a strong beast.
There is someone on here that is approaching 500K miles on their Cummins. About time for a valve job, no?
regards, as always, jefe
