I'm looking for the best service manual for my 2017 Ram 2500 w/6.7. I've spent close to 10K in the last couple of months on anything and everything that can go wrong at 135K miles. The dealership has informed me I now need a new particulate filter and that's another 5K plus. I've found a place that cleans them on a regular basis and going to try it, but I'm looking for torque specs for the flange nuts for the particulate filter along with torque specs on the 2 exhaust temp sensors in the particulate filter and the differential pressure sensor tubes going to the particulate filter.
