Ok, so i know how a locker operates and works, but what about soppls and mini spools? How do they work? and how are they different from just welding up the diffs. and then, whats a full floating axle. oh, and one more thing, how do unimog and volvo laplander axles compare to normal axles and has anybody used them in a toyota? THANKS!

Spools do the same thing as welding the diffs, connecting the ring gear to the carrier so there is no differentiation between L + R wheels. A spool bolts in.

Portal axles have a gear reduction unit at each wheel. Someone somewhere has probably used them on a Toy.

A semi-floating axle is has an axleshaft 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. This assembly typically mates to the end of the axlehousing using some type of flange arrangement. The axleshaft also rides on a large roller or ball bearing out at the end of the axlehousing.
The axleshaft in a semi-floating assembly serves two purposes. First, it attaches to the wheel and is used to support the weight of the vehicle and its cargo. Second, the axleshaft must transmit the rotational torque from the differential out to the wheel.


A full-floating axle uses an axleshaft on each side that is simply splined at both ends or splined on the inner end and has a drive flange on the outer end. The shaft mates to the differential in the same way as a semi-floater. However, the outer end of the shaft differs. The splined end of the shaft slides into a locking hub or an internal splined steel drive plate that bolts to a hub cap, similar to what is found on a front axle. In some cases, the drive flange may be part of the shaft itself. In either case, the axleshaft is allowed to float in the system.

For a full-floater system, the axleshaft only serves to transmit the rotational torque from the differential out to the wheel. It does not carry the weight of the vehicle like a semi-floater does. On a full floater, a spindle is attached to the outer end of the axlehousing. The hub's cap is attached to this spindle and rides on tapered roller bearings. It's this yhat carries the vehicle weight. A full-floating axle is stronger than a same sized semi-floater.

Thanks for clearing thing up!
