Taking the plunge. My journey as an O/O.

I will double check, but I believe the axle is rated at 20k. Will check inside the door after dinner.

 

I will need to check the manual. The inside of the door indicates 12,350, but it also specifies a specific tire type, and that tire type happens to have a per tire rating of 6175. Not sure what the limiter there is.

Rear axles are rated to 20k.

 

I can definitely see a difference in side bulge between the old tires and the new. It's noticeably less with 16 ply. Even at the same air pressure. I run steers at 110 cold.

 

Well,

Seems like 4238 is not done needing me to spend money on her.

Getting DEF quality errors. Not filter errors.

She derated on me twice. The first time she derated, I stopped, checked the codes, and added more DEF, filling it completely full, hoping to dilute the impurities, if they were real. The error on the dash dropped a step, and the derate ended.

15 minutes later, the derate resumed, lasted ten minutes, and ended. The first level dash error code has been constant all morning though.

So, here I am, stopped at a TA that can read Freightliner codes.

I am hoping this is simply a bad sensor, and the sensor is not stupidly expensive, or difficult to replace.
