Im a newer driver at a mega carrier and I'm switching to OO. They got me set up to buy (not lease) a 2016 DD15 Cascadia with 12 speed auto. The truck has 475k miles and a powertrain warranty for a year from purchase. The configuration is correct for the loads I haul and I'm currently in an identical company truck and like it. The price is reasonable to market so I'm pulling the trigger.
What should I check on the truck before I sign?

Transmission and differential oils are now due to be changed.
Find out if the DPF filter has been changed, if not that will be due soon.
Ask if O-rings on tubes from oil pickup to oil pump have been changed. They'll be due, but not expensive to change.
SCR in One-Box will go around 600-700,000 miles, $10,000 plus replacement.
Engine should be good to a million or more.Truemac, royal55flush and spsauerland Thank this. -

I usually check the engine oil pickup O-rings first start in the morning. Watch the Oil pressure gauge. If they are due you’ll find the pressure erratic jumping from 50-60 psi in the first few minutes. (That’s the air that seeped in when it was shut down being purged)
When they are worse you’ll see it jump a around a couple times in the 20 psi area (before shooting on up).
When they past due, the oil pressure light will flash when you make corners to fast!!
So definitely check for the suction o-rings.royal55flush, uncleal13 and magoo68 Thank this. -
Stay a company driver, these Post-Emission trucks will nickel and dime you till you’re broke.
