If you think for one moment that your going to buy a used truck,.. and it be even remotely ready for freight, you are squarely living in laa,laa land...

The typical stuff one can expect to do up front BEFORE PUTTING IT ON THE ROADS!!! when buying a truck of that mileage range...

- The fuel pump will need a re-build / all new guts ASAP.

- The cans will need to be pulled off and baked, DE-ashed, and flow tested. Plus an inspection of the SCR element and de-comp tubing.

- A very thorough EGR tune-up + cleaning out all piping, egr valve, etc. replace of all related sensors, replace Doser injector, replace exhaust gas pressure sensor and ensure piping/supply circuit is clean.

- Cleaning out of the DPF crossover tubing for the DPF Delta-P sensor, and replacement of the sensor itself.

- Replacement of DEF screen filter, inspection and very high likeliness of replacing all 3 of the the NOx sensors, as they are only good for about 200-300k miles at a time.

- re-torque of all wheel bearings.

- Inspection of overhead cam, and re-adjustment of the valves.

- Rail pressure leak-down tests and replacement of anything that makes it fail.

- pressurize whole engine and check it for air and egr leaks.

- 3 or so oil changes in very short intervals (3,000 miles or so) to de-soot the internals of engine, so that maybe,.. just maybe you can get another 300k miles out of it before the thing has so much carbon packing that it eats up the rings and.or the overhead cam.

- Shocks, drive-line inspections, replacing oil in all gear boxes, king pin and bushing inspections using an actual dial indicator and not guessing it like a fool, replacement of cab air bags, and shocks, inspection of rear air bags, belt replacements and pulley inspections, ...,...,...


The list only grows form there. Here is some related info ...

-- Owning a modern truck is NOTHING like driving one for a comapny ... I hope you got a lot of wrenches, and have invested in diag.software to go along with that truck pourchase .. otherwise, your pissing up wind and your fate of typical O/O struggle mode or failure is sealed.

Everything Rawze stated above is the honest to God truth. These trucks are junk when they roll off the assembly lines, I have been in the plants, they will tell you that on the dock... And the mechanics that maintain these units, in most cases do not give a sheet or are told to ignore many issues to keep the trucks rolling until they can sell them off to the next sucker.

If you buy this truck or another, budget money for diagnostic equipment and tools. An Inline 6 reader and a laptop are at the top of the list, especially if you are going to keep the mandate intact. You will need gear to pressure test the coolant system, fill the coolant system, tools to do the overhead, bar the motor, etc... A good idea of how electrical can bus systems work and the tools to do repairs properly and be able to read electrical schematics.

If you don't do the above, and rely upon warranties and shops, you will be broke and scratching your head in little to no time. These shops will repair your truck, and empty your wallet. You will quickly discover that repairing a truck, does not mean FIXING the truck.

You know, I never owned more than a simple set of Craftsman tools... My trucks rarely had any issues, the shop I used treated me right, had those old school mechanics that diagnosed with their ears, eyes and years of experience, those guy that have now passed away or retired are sorely missed. I can rattle off the issues I have had with my old iron, and it would not even fill half a page of a sheet of typing paper... My EPA truck, Encyclopedia Brittanica baby.

You are in the right place, and it will sound overwhelming, and it can be, but unfortunately this is the reality of today, unless you buy new and trade in every three years... Honestly, there is no way around what has already been stated.

One thing, I would take me at my word on this, buy a Cummins. Yes, they have their issues, but they also supply you with the tools to keep the motor running. I in framed this motor of mine, CM-871 in Rawze's driveway, using my iPhone. Try that with a Detroit, PACCAR or Volvo, ain't going to happen.
