What is the 2010-2025 RAM 2500 Exhaust Manifold Cracking (6.7L Cummins)?

The cast iron exhaust manifold on the 6.7L Cummins turbo diesel cracks due to thermal cycling stress, particularly near the center cylinders (#3 and #4). Cracks allow exhaust gases to escape, creating a ticking noise on cold start that diminishes as the manifold expands when warm… Repairs typically run $600-$1,500. Severity: medium.

What is the 2003-2018 RAM 2500 Front Axle Pinion Seal Leak (AAM Front Differential)?

The American Axle (AAM) front differential on Ram 2500/3500 4x4 trucks is well known for recurring front pinion seal leaks. The pinion seal rides on a sleeve/wear surface on the pinion flange; over time the seal wears a groove into the sleeve, so simply installing a new seal on a… Repairs typically run $200-$550.
