You guys have fun wheelin. I'll be doing a clutch, hydraulics/ pilot bearing, input shaft, whatever- in the Cummins . Started f'n up in Moab, it's gettin worse. Driving it today absolutely sucked. I need to fix it now. Should be back to towing duty within 3 weeks. Found the real problem, 4500, Oh Crap- Input bearing or mainshaft endplay issue Thanks goes to Rene for the advice/ experience.
