ABOUT THIS SEAL

The rear main seal sits on the crankshaft flange at the transmission end of the RAM 50 engine, keeping oil inside the crankcase while the crankshaft spins freely.

On RAM 50 models this seal hardens with age and mileage, and once it fails oil weeps onto the clutch or torque converter, gradually dropping oil level and risking clutch slip on manual variants.

COMMON SYMPTOMS OF FAILURE

• A burning clutch smell under load
• Dropping oil level with no leak visible at the sump or rocker cover
• Oil spots under the vehicle near the bell housing
• Slowly dropping oil level with no other visible leak
• Clutch slipping or reduced bite in manual vehicles
