Sometimes it will restart of sometimes it doesn't right away but after about thirty minutes it will restart. This is also true of parking lots and city streets.

Pinion nut on rear differential came off and pinion fell into differential causing rear wheels to lock up at interstate speeds.

- Thompson Station, TN, USA

While driving on a local road at approximately 35-40mph the vehicle started making a loud vibration noise. Within the next 3 miles the truck made a loud banging noise, the truck lurched and lost forward momentum. I was able to safely make it to the shoulder of the road where I discovered that the driveshaft had separated from the rear differential and had been rotating, banging the underside of the truck. The pinion nut was no longer attached to the pinion gear. The spline from the differential's pinion gear was askew and fluid was leaking out. The towing service indicated that the rear wheels were locked and the wheels would not rotate as the vehicle was dragged onto a flatbed. The transmission shop who conducted repairs confirmed that the rear axles was locked up and the differential would require a rebuild. This situation mirrors the NHTSA preliminary evaluation PE14-019 and linked to Chrysler's recall P77 / NHTSA 14V-796, with the difference being that this occurred on a 2004 Dodge Ram 1500 not a 2005 Dodge Ram 1500. The 2004 Dodge Ram was manufactured within the same time frame as the 2005 Dodge Ram in the recall (January 28, 2004 - August 3, 2005), June 2004. In addition the rear axle assemblies between the 2004 and 2005 Dodge Ram 1500S are interchangeable.

Heard grinding noise in back of truck driving straight at 45 mph on highway, truck skidded to a stop and I found the driveshaft at the back differential had broken off. Could not move truck in drive, 4WD or push in neutral due to the back diff locked up. Back wheels locked due to differential. Mechanic diagnosis is it needs a whole new differential and driveshaft. Highway was single lane with on coming traffic and I was lucky to miss a head on collision.

- Clifton Park, NY, USA

Driving on a 3 lane heavily trafficked road, and all of a sudden my drive shaft falls out of my truck. This locked my wheels up, started shaking my truck violently. I was extremely lucky that someone was not directly behind or adjacent of me because it would've resulted in a sure collision.

- Staten Island, NY, USA

I was approaching a stop. There was a slight whine as I decelerated. Then a clunk and a loud bang. The rear wheels locked up and I stopped immediately in the middle of the road. The driveshaft had fallen out from the differential and was on the ground. I was only going 25-30 mph at the time. Luckily I had just gotten off the highway. I had it towed to the dealer and they said the pinion nut had come loose. My wife was looking on the internet and found this problem had been a recall but the dealer said it was VIN specific and mine wasn't included in the recall. They need to expand the recall!!! if it had happened just a few minutes earlier I could have been involved in a deadly crash.

I own a black 2004 Dodge Ram 1500 4X4 4 door short bed with 146,466 miles on it. I have owned this truck from new, almost 14 years. Never has a pinion nut back off the pinion before. We had just got off the main hi way speed was 55 mph and turned onto a back road speed was 35 mph. When out of know were there was a loud bang from under the back off the truck. Then the drive line fell off of the rear end and banged around until I could get the truck over to the side of the road and stopped. Went to the dealer the next day to find out that there has been problems with the 1500 truck rear ends, but per my VIN number on my truck it is not covered by a known problem. Only the 2005 and 2006 1500 trucks a covered. It seems that the 2004 Dodge Ram 1500 trucks have the same pinion nut issue as the 2005 and 2006 1500's. this could have been a very different out come if we were on a freeway were the speeds are anywhere from 55 to 75 mph. I would hope the manufacturer of these trucks will take a look into the 2004 Dodge Ram 1500 pinion nut issue before someone is killed because of a manufacturing process error.

Vehicle suddenly began making a loud droning sound while going around a corner on residential streets, reminiscent of an airplane flying overheard or a semi truck's "jake brake." The sound stopped after the vehicle straightened out. On the next two corners, the droning sound repeated, and vibration was also felt coming through the floorboards, but the sound went away after straightening the vehicle out. After the second corner, the vehicle accelerated to about 20 mph. There was a sudden loud bang. Both back wheels locked up immediately, as evidenced by the skid marks on the road. The driveline also disconnected from the rear differential at that time, leaving a trail of oil on the road. The mechanic who inspected and repaired the vehicle indicated that the nut securing the pinion gear had come loose, allowing the pinion to move out of its correct location. The result was that the axles to both rear tires locked up. It appears that similar issues related to pinion nuts loosening have been found on many other vehicles of this make and model. Recalls were issued for over 250,000 Dodge Ram 1500 vehicles from the 2005 model year to correct an issue with the nut on the pinion. Over 250,000 additional Dodge/Chrysler vehicles from the 2009 to 2012 model years were also recalled for a pinion nut issue.

Additionally, the drive train, rear end gears, and bearings needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and stated that the VIN was not included in NHTSA campaign number: 14V796000 (power train). The approximate failure mileage was 155,000.

Vehicle rear end has gone out. Took vehicle to dealer as instructed by fca due to noise in rear end. Dealer drove.1 miles and determined rear end is bad. Pinion nut is loose causing pinion gear to move. Advises Chrysler of such to no avail. Vehicle started making noise in rear end at 42000 miles. Advises Chrysler that there is no reason this part should be coming loose that it a manufacturer S defect. Told that vehicle is out of warranty and that it is my problem. This is a serious issue that can cause injury if control of vehile is lost due to rear wheels locking up.
