What is semi floating axle?

A semi-floating axle is very common on the rear of most 4WDs. It consists of an axle shaft on each side that is splined on the inner end where it mates to the differential and has a wheel flange where the wheel studs mount at the other end. The wheel hub is mounted on this spindle and rides on tapered roller bearings.

What are floating axles?

A full-floating axle carries the vehicle’s weight on the axle casing, not the halfshafts; they serve only to transmit torque from the differential to the wheels. They “float” inside an assembly that carries the vehicle’s weight. Thus the only stress it must endure is torque (not lateral bending force).

What are semi axles?

One bearing supports the axle shaft, and the other goes inside the axle casing. Since it has two bearings, a semi-floating axle needs to be larger than the other options to produce the same torque. Semi-floating axles are used for cars, SUVs, and mid-size trucks, such as half-ton and light duty pickups.

What does a semi floating axle shaft do?

The semi-floating axle design fastens the wheel directly to the flange on the outboard end of the axle shaft and a single bearing supports the outer end of the shaft. The axle shaft has to support the weight on the axle and the propulsion forces from the engine twisting it.

What is a 3/4 floating axle?

Three quarter floating axle | Types of Live Rear Axles In this axle, the wheel hub is supported by the single bearing located in the center of the wheel hub. The wheel hub runs on the axle housing. The axle shaft is keyed rigidly to the wheel hub.

What does a full floating rear end mean?

-Full floating axles like we supply are held in by nothing. That’s right, they literally float inside the rear end. The full floating axles are SPLINED on both ends, so they only DRIVE the wheel and do not support the weight of the vehicle.

What is a full floating rear end?

The article has been updated successfully. What is a full floater rear end? A full floater axle is a double splined non-flanged axle shaft with splines on both ends. The rear housing end has hubs on the end where the bearings are installed and a drive flange where the studs are installed, not on the axles like a standard rear end.

What’s a floating rear axle?

A rear axle that drives the vehicle and is a full floating axle uses drive plates that attach to the wheel hub and axle to drive the vehicle. Used in competition, this style of axle is used so that the wheel will not leave the vehicle in the event of a broken axle.

What is a stud axle?

A stub axle or stud axle is either one of two front axles in a rear wheel drive vehicle, or one of the two rear axles in a front wheel drive vehicle.

What is steel for axle?

An axle shaft is a solid steel shaft that runs from the differential and gear set of an axle housing to the wheel. Used in two distinct configurations, the axle shaft can be a straight shaft with splines machined into each end to engage both the differential on one end and a drive flange on the other.
