On the 2007-2018 RAM 3500 6.7L Cummins, the 2007-2018 RAM 3500 with the 68RFE 6-speed automatic transmission suffers from premature failure when towing heavy loads (over 10,000 lbs). The 68RFE is a derivative of the older 545RFE and was not adequately engineered for the torque output of the 6.7L Cummins. The overdrive clutch pack, solenoid pack, and torque converter are the primary failure points. Overheating during sustained towing destroys the clutch packs and warps the valve body. Many trucks experience complete transmission failure between 80,000-150,000 miles if used for regular towing. Rebuild cost: $3,000-5,000. Built/upgraded transmission: $5,000-8,000.

This issue also affects: Acura MDX, Audi A4, Audi A6

Common Symptoms

Transmission slipping under heavy load
Flare between 3rd and 4th gear
No 3rd gear or no overdrive
Transmission overheating warning while towing
Harsh or delayed shifts
Check engine light with transmission codes
Complete loss of forward or reverse gears

How to Fix

For minor issues: Complete fluid and filter change with Mopar ATF+4 (68218057AA) and solenoid pack replacement ($400-800). For overheating prevention: Install an auxiliary transmission cooler and keep temps under 220F. For rebuilds: Use a reputable heavy-duty builder (SunCoast, Randys Worldwide, BD Diesel). A properly built 68RFE with billet shafts, upgraded clutch packs, and triple-disc torque converter ($5,000-8,000) will handle 800+ lb-ft of torque. For 2019+ trucks, the Aisin AS69RC replaced the 68RFE.

On the 2010-2025 RAM 3500, the front hub bearings (wheel bearing assemblies) in the RAM 3500 fail prematurely, particularly on trucks that carry heavy loads in the bed or tow heavy trailers. The factory hub bearings are adequate for unloaded driving but wear rapidly under sustained heavy GVWR/GCWR conditions. 4x4 models are more affected due to the additional stress of the front axle components. Bearing failure typically occurs between 60,000-100,000 miles on heavy-use trucks.

This issue also affects: Chrysler 300, Ford Escape, Ford Fusion

Common Symptoms

Humming or droning noise that changes with vehicle speed
Noise increases when turning in one direction
ABS or traction control warning light
Play or looseness felt in the front wheel
Vibration in steering wheel at highway speeds

How to Fix

Replace the front hub bearing assembly (Timken HA590576 or Moog 515162 are highly rated). The hub bearing is a bolt-on unit on these trucks — 4 bolts from the back of the steering knuckle. Replace both sides if one has failed, as the other is likely not far behind. Use ABS-compatible hub assemblies. Budget $300-$700 per side for parts and labor.

TipTimken HA590576 and Moog 515162 are the top choices for replacement. Avoid cheap imported hub bearings — they often fail within 20,000 miles on a 3500 that tows.
TipWhen one front hub bearing goes, replace both sides. If one failed at 80,000 miles, the other is likely at 85% wear and will fail within 10,000-15,000 miles.

On the 2010-2025 RAM 3500 6.7 Cummins, the intake grid heater relay fails, preventing the grid heater from warming intake air during cold starts. The grid heater draws significant current (up to 200 amps), and the relay contacts eventually burn and weld or fail open. Without the grid heater, cold-start performance degrades significantly in temperatures below 40°F — longer cranking, white smoke, rough idle, and potential no-start conditions in extreme cold.

This issue also affects: RAM 2500

Common Symptoms

Hard starting or extended cranking in cold weather
White smoke on cold start
Grid heater warning light not illuminating
Rough idle for several minutes after cold start
Check engine light with grid heater circuit codes

How to Fix

Replace the grid heater relay (Mopar 56055666AB or equivalent). The relay is located on the intake manifold or firewall area and is a straightforward replacement. Some owners upgrade to a heavy-duty aftermarket relay rated for higher amperage to extend lifespan. Also inspect the grid heater element itself for damage or corrosion while the relay is being replaced. Budget $80-$250 for parts and labor.

Parts and tips from 0+ owners who fixed this issue

TipThe grid heater relay is cheap and easy to replace yourself. Keep a spare in the glovebox if you live in a cold climate — a $30 relay can save you from a no-start situation in winter.
TipWhen replacing the relay, inspect the connector terminals for heat damage or corrosion. Burned terminals will kill a new relay quickly — replace the pigtail connector if damaged.

On the 2010-2025 RAM 3500 6.7L Cummins, the exhaust manifold mounting studs on the 6.7L Cummins break due to repeated thermal expansion and contraction cycles. Broken studs allow the manifold to separate from the cylinder head, creating exhaust leaks that produce a ticking noise and reduce turbo efficiency. The center studs (#3 and #4 cylinders) fail most frequently. Attempting to remove broken studs often requires extracting them from the cylinder head, adding complexity to the repair.

Common Symptoms

Ticking or hissing noise from the exhaust manifold area
Exhaust leak noise that changes with engine RPM
Soot or carbon deposits around manifold-to-head joint
Noise louder on cold start and fades slightly when warm
Slight power loss from exhaust leak affecting turbo

How to Fix

Remove broken studs using a left-hand drill bit and easy-out extractor set. If the stud breaks flush or below the head surface, a professional machine shop extraction may be needed. Replace all studs with upgraded ARP 247-4206 stud kit, which is stronger than OEM. Always replace the exhaust manifold gaskets during this repair. Budget $400-$1,200 depending on how many studs are broken and whether machine shop extraction is needed.

TipARP 247-4206 exhaust manifold stud kit is the definitive upgrade. Stronger than OEM and far less likely to break again. Worth the investment on any Cummins.
NoteSoak broken studs with PB Blaster for 24+ hours before attempting extraction. Rushing the extraction is how studs break off flush with the head, turning a $400 job into a $1,200 machine shop visit.
