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.

Dodge Challenger Shaker cars get Shakedown package stripes

In 2016, Dodge brought a custom 1971 Dodge Challenger to the SEMA show called the Shakedown. It melded modern Challenger parts with the classic model's body, and did so almost seamlessly. It of course featured a shaker hood scoop, and it also had a set of stripes to one side that gradually decreased in size to give the feeling of vibration and movement. The reception was clearly good, because Dodge has created a set of stripes just like those on the show car for modern shaker Challengers and made them available in a package with the Shakedown name. The Shakedown package is new for 2018 and available only on Challengers with the shaker hood scoop. These include the R/T Shaker, R/T Plus Shaker, and 392 Scat Pack Shaker. Just like on the concept, the stripes are all to one side and wrap around the hood scoop. The only difference is that they're all one color, whereas the '71 custom car had one stripe in red. In addition to the stripes, the package adds white-face gauges and an upgraded Alpine audio system. On R/T and R/T Plus models, this system has six speakers with a 275-watt amplifier, while the system on the Scat Pack has nine speakers with a 506-watt amplifier. The cost of the Shakedown package is $995, and it's available with any color of Challenger Shaker. And on the topic of colors, Dodge has also revived Plum Crazy and B5 Blue for 2018 Chargers and Challengers. Those colors will be available on any Charger or Challenger regardless of trim level.

Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point.
