NHTSA investigating Ram 1500 models for rear differential failure

The National Highway Traffic Safety Administration is investigating Fiat Chrysler Automobiles and its Ram brand following a number of reports regarding the 2005 Dodge Ram 1500 pickup. According to 15 consumer complaints, the trucks' rear differential locked up while in other cases, the driveshaft separated at its connection to the diff.
Nearly half of the reports claim the truck was traveling at or above 50 miles per hour, while two consumers reported that the diff lockup/driveshaft separation sent their pickups into a spin. Most troubling, though, is that consumers reported little to no sound indicating there was a problem with their truck.
We reached out to Ram for additional information, such as how many vehicles may be affected or what equipment might be fitted that could cause the issue. Unfortunately, the company wasn't willing to elaborate on specifics.

Watch these Dodge Demons explode on a Texas drag strip

The Dodge Challenger SRT Demon is extremely quick. It can hit 60 mph from a dead stop in less time than it takes to read this sentence thanks to its supercharged 6.2-liter V8. That engine makes up to 840 horsepower and 770 pound-feet of torque, depending on what octane is running through the fuel lines. That's a ton of power going solely to the rear wheels. So much so that Dodge developed a number of features and a new set of tires specifically for the car. In our time with the Demon, the car took abuse run after run on a drag strip without skipping a beat, but it seems some actual owners aren't quite so lucky. Just take a look at what happened to a few of these cars. You can see the whole car shake and jitter right as the whole rear explodes in front of the tree. It seems the initial shock from the launch — the most taxing bit of any drag run — is what kills the differentials. Catastrophic failure is rarely pretty, but it is neat to see the whole thing occur in slow motion. Three more cars — four stock and one modified in total — suffered similar fates. Not a great look for Dodge or SRT. According to The Drive, a private drag event in Texas drew a number of Demon owners all trying to beat NHRA NHRA Top Fuel racer Leah Pritchett's time in her personal Dodge Demon — 42 stock Demons attended along with five modified cars. While no one managed to match her 9.65-second quarter-mile run, a few owners did dip below 10 seconds. Now, there are a few of caveats we must address. First, with any modified car, you run the risk of breaking something, even with a car that's set up from stock specifically for drag strips. Even a set of tires like the Mickey Thompsons shown in the video above can have an effect on driveline components. Horsepower may be king, but it's torque that's the rear killer. All that torque sends a shock through the car. Adding even more with aftermarket parts increases the risk of something failing. The modified car was apparently pushing out about 1,000 horsepower. That said, four of the five vehicles were stock, so any extra power or torque should theoretically be a non-factor. The drag strip's surface was maintained by a company called Mass Traction. FCA used Mass Traction during the Demon's development, so that too should be a non-factor in the part's failure. It's unclear what exactly caused the failures, though The Drive reports that FCA officials are investigating the matter. Related Video: This content is hosted by a third party.

Dodge Demon test mule spotted wearing unusual camouflage

The Dodge Demon apparently refuses to stay under wraps. The endless rollout of teasers continues each Thursday, but thanks to both Vin Diesel and our trusty spy photographer we have a whole suite of photos that show a nearly complete car in the flesh. This car appears to have been hiding in plain sight, as some of these photos were captured in the Detroit area. The car or cars in these photos is far less polished than the one shown in all of Dodge's teasers. The Air Grabber hood is unpainted, though it does come with some awesome hood pins. The same goes for the bolt-on fenders, as other pictures show a cleaner integration of the Demon's widebody modification. Despite the large Nitto logo on the top of the windshield, the cars in these photos are both wearing a set of Pirelli PZero All-season Plus tires on non-Demon wheels. It's as if drag radials aren't the best choice for winter driving. This car is fitted with two-piece Brembo brakes, but there's no telling if they're different than the standard Hellcat's. The decals on the side of the car may give clues to some of the Demon's equipment, but based on the LB Performance - commonly known as Liberty Walk- logo, the decals are likely more of a ruse than anything else. Liberty walk is famous in the tuning community for big, bolt-on body kits. The looks perfectly suit these test cars, though Borla exhaust and a Hurst shifter would be a wonderful addition to the Demon. Outside of that, there isn't much new to glean from these photos. Most of our questions about the Demon (horsepower, gearing, price) can't be had from pictures. Look for more news each Thursday in the lead up to the car's debut in New York in April.
