RAM became its own brand in 2009, but the trucks underneath wear the same DNA they've had since the 1994 redesign: solid axles where it matters, a coil-spring rear that drives better than competitors' leaf-spring setups, and the Cummins 6.7L diesel with its own cult following. The HEMI 5.7L and the EcoDiesel round out the gas and small-diesel options. Around Seguin, RAMs work — towing trailers, hauling materials, running daily contractor commutes. Frank's Automotive services RAM with diesel-specific diagnostic capability and gas-truck depth.
RAM issues we see most often
- Cummins 6.7L diesel — EGR cooler clogging, EGR valve, DPF (diesel particulate filter) regeneration issues, injector wear on high-mileage trucks. Cummins service is technical and where many shops get out of their depth; we don't
- HEMI tick (5.7L V8) — sometimes harmless lifter noise, sometimes worn cam follower / lifter; diagnostic determines which
- HEMI MDS (multi-displacement system) — similar concept to GM AFM, similar lifter-failure pattern on some years; diagnostic-driven decision on repair
- Death wobble — 4WD RAM 2500/3500 with worn steering linkage components; we find the cause and replace the right part (often track bar, drag link, or steering stabilizer)
- 65RFE / 66RFE transmission torque-converter shudder — fluid flush often catches it
- EcoDiesel 3.0L — oil cooler, EGR cooler issues at high mileage
- Hood paint peeling / fading — known on certain years (cosmetic only)
