Common Problems & Known Issues

The 2009 Ram 3500 is split by powertrain: the 6.7L Cummins is generally bulletproof but got unfortunate early-generation emissions equipment; the 5.7L Hemi in heavy-duty service sees piston/ring failures and transmission abuse. Steering linkage wear is universal across all configs.

Steering Linkage and Tie Rod End Failure

Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: wandering or vague steering feel, clunking over bumps, uneven tire wear on front end, steering wheel off-center after hitting potholes
Fix: Outer tie rod ends wear first, then inner sockets and drag link. Complete linkage overhaul takes 3-4 hours; alignment required after. NHTSA recalled tie rods multiple times for separator issues — check recall status before buying.
Estimated cost: $600-1,200

68RFE Transmission Cooler Line and Mount Failures (Diesel)

Common · medium severity
Typical onset: 80,000-150,000 mi
Symptoms: transmission fluid leaking near radiator or bellhousing, transmission running hot, clunking during shifts, broken or sagging transmission crossmember
Fix: Factory cooler lines corrode at crimps; mount cracks from torque cycling. Replace lines and cooler (4 hours), replace mount (2 hours). If fluid contaminated coolant or ran low, expect internal clutch damage requiring rebuild (12-16 hours).
Estimated cost: $800-1,400 for lines/mount; $3,500-5,500 for rebuild

DPF and EGR System Failures (6.7L Cummins)

Common · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: check engine light with P2002 or P0401 codes, repeated forced regen cycles, loss of power in limp mode, excessive soot buildup in intake
Fix: 2007.5-2009 Cummins emissions are first-gen junk. DPF clogs if used for short trips; EGR cooler cracks leaking coolant into intake. DPF replacement 3 hours; EGR cooler 6-8 hours. Many owners delete (off-road use only per EPA).
Estimated cost: $1,200-2,000 DPF; $1,800-2,800 EGR cooler

Piston Ring Land Failure (5.7L Hemi)

Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: excessive oil consumption (quart per 500-1,000 miles), blue smoke on startup, misfires on cold start, loss of compression in one or more cylinders
Fix: Ring lands crack from detonation or sustained towing abuse. Requires cylinder head removal and bore inspection; if scored, full rebuild or replacement. Engine R&R 14-18 hours; short block replacement adds 8-12 hours machine work.
Estimated cost: $4,500-7,500

Transfer Case Shift Motor and Encoder Failure (4WD)

Occasional · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: 4WD not engaging or disengaging, service 4WD light illuminated, grinding noise when selecting 4WD, stuck in 4WD low
Fix: Shift motor wears internally or encoder position sensor fails. Motor replacement 2-3 hours; encoder 1.5 hours. Verify transfer case fluid level first — low fluid accelerates wear.
Estimated cost: $600-1,100

Front Axle Vacuum Hub and Actuator Issues (4WD)

Occasional · low severity
Typical onset: 60,000-110,000 mi
Symptoms: 4WD engages but no power to front wheels, hissing from front axle, intermittent 4WD function, 4WD works after driving then quits
Fix: Vacuum lines crack; axle disconnect actuator diaphragm tears. Replace vacuum lines and actuator (2 hours). Common on trucks in rust belt. Upgraded manual hubs available as permanent fix.
Estimated cost: $400-700

Ball Joint Wear (Front Axle)

Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: clunking over bumps, steering wander at highway speed, uneven tire wear, visible play when prying on tire at 12-6 o'clock
Fix: Upper and lower ball joints wear faster with oversized tires or plow use. Uppers fail first. Replace all four (6-8 hours); alignment required. Moog or Dynatrac units last longer than OEM.
Estimated cost: $1,200-1,800
Owner tips
  • Change transfer case and differential fluid every 30,000 mi if towing — factory fill is inadequate for sustained loads
  • Inspect steering linkage every oil change; loose tie rods become dangerous fast on a 10,000-lb truck
  • Diesel owners: Use fuel additive with lubricity and change fuel filter every 10,000 mi to protect CP3 injection pump
  • Hemi owners towing heavy: Install transmission temp gauge and auxiliary cooler; 68RFE runs hot and clutches glaze quickly
  • Flush coolant every 50,000 mi on Cummins trucks to prevent EGR cooler failure
Buy the Cummins if you can wrench or budget for emissions deletes; avoid the Hemi for serious towing unless transmission has already been built — but either way, expect to replace front-end components by 100k.
