How do I identify my Eaton rear axle?

Model Identification Axle Housings are identified by the specification number stamped on the rear right hand side of the axle housing. This number identifies all components of the axle as built by Eaton, including OEM special requirements such as yoke or flange.

How does an Eaton 2 speed rear end work?

The 2-speed axle works on the same basic principles, but with an added planetary gear set inside the ring gear. In high range, the planetary gears don’t do anything and the differential works totally normal. This works by sliding a clutch gear meshing with the high range clutch plate.

What is a two-speed rear end?

The dual-ratio differential is exactly what its name suggests: the rear differential provides two different gear ratios: a shorter one for maximum tractive force for faster acceleration or steep grade-climbing capability, and a taller one for quiet, fast highway cruising (the Columbia two-speed axle was said to be able …

What is an Eaton axle?

The Eaton DS404 is the lightest standard 40,000 lb. tandem axle in the industry. Options include differential lock, pump, and wide-track housing. Its larger inter-axle differential assembly and lockout clutch design make it ideal for a wide range of vehicles and applications.

How can you tell if you have a limited slip differential?

The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.

What is double reduction axle?

1. DOUBLE REDUCTION AXLE: (1) A double reduction axle construction in which two sets of reduction gears are used for reduction of gear ratio to produce higher torque.

How does hub reduction axle work?

In a rear axle with hub reduction, the gear reduction takes place in two steps. This means that the load is split up and there is little load on the driveshafts and the final drive. It is a reliable design consisting of a cylindrical planetary gear with straight needle bearing gears, which gives small losses.

How does a planetary axle work?

Rockwell-Standard Planetary Axles permit the mesh with teeth of the planet spur gears. The bevel or hypoid gearing of the carrier, and the axle planet spur gears rotate on planet pins which are shafts to carry only a nominal torsional load while mounted in a spider.

What is a double reduction differential?

DOUBLE REDUCTION AXLE: (1) A double reduction axle construction in which two sets of reduction gears are used for reduction of gear ratio to produce higher torque.

What is the best ring and pinion manufacturer?

DANA gears are the best IF you can get them.

What is the difference between Positraction and limited slip differential?

The limited-slip differential is similar to the positraction differential, but allows the wheel with traction to have only a limited amount of greater power than the wheel that is slipping. A limited-slip differential will prevent the tire with less traction from separately spinning.

What is the rear end ratio?

Rear end gear ratios or final drive ratio refers to the number of revolutions the drive shaft turns compared to one full revolution of rear wheels. A 2.90 gear ratio means the drive shaft turns 2.9 times in one full turn of the rear wheels.

How does a two speed axle work?

The 2-speed axle works on the same basic principles, but with an added planetary gear set inside the ring gear. In high range, the planetary gears don’t do anything and the differential works totally normal. This works by sliding a clutch gear meshing with the high range clutch plate.

What is a two speed differential?

A two-speed differential adapted for use in motor vehicle driveline applications. The two-speed differential is capable of selectively transferring power to either a first drive mechanism for establishing a first drive speed ratio or a second drive mechanism for establishing a second drive speed ratio.
