LOUISVILLE, Ky. — ArvinMeritor has unveiled a new tandem axle to deal with issues relating to driveline angularity.

According to the company, the new axle will virtually eliminate vibration throughout the entire drivetrain.

The MT-40-143-MA-N carriers a 40,000-lb. gross axle weight rating and is designed with a rear carrier with Amboid gear designs to provide above centreline positioning of the drive pinion. This positioning greatly reduces interaxle driveline angularity, which in turn minimizes driveline vibration, according to ArvinMeritor.

In addition to reducing cab noise and vibration, the reduction in driveline vibration minimized damage to all other drivetrain components.

Incorporated in the new design is an integral pinion bearing cage, to eliminate the bearing-cage-to-carrier joint and its associated potential-leak path.

The ratio range on the new axle is 2.64 to 4.11, which covers the majority of the linehaul market.

The new axle will be available in July through all OEMs and will be covered by the company’s five-year/750,000-mile linehaul warranty.
