Common 1991 Dodge W350 problems

The Dodge D350 1991, a heavy-duty pickup truck, is known for its reliability and robustness. However, it is not without its common problems, which are primarily related to the manual transmission, engine, and electrical systems.

Manual Transmission Issues:
Manual transmission problems are a common issue in the Dodge D350 1991, particularly with the 5th gear and reverse gear. The synchronizers in the manual transmission can become underlubricated and worn, causing grinding or popping out of gear. These problems can be expensive to repair if not addressed promptly, making them a significant concern for D350 owners.

Engine Problems:
The D350's engine, a 5.9L Cummins diesel engine, is known for its durability and reliability. However, it can suffer from a problem known as the "Killer Dowel Pin" or KDP. This issue refers to a dowel pin failure inside the engine, which can lead to catastrophic engine failure if not addressed promptly.

Electrical System Problems:
The D350's electrical system can also be a source of problems. The headlights in these trucks do not run off a relay, and the switch carries the entire load, which can lead to failures and even fires if not addressed.

In summary, the Dodge D350 1991 is a reliable and robust truck, but it is not without its common problems. Manual transmission issues, engine problems like the Killer Dowel Pin, and electrical system problems are the most common issues reported by D350 owners. Regular maintenance and prompt attention to these issues can help ensure the longevity and reliability of this heavy-duty pickup truck.
