Is a Ford 9 inch a full floater?
A conventional 9-inch rearend is known as a semi-floating axle because, though axles float, they also carry vehicle load via the axle bearings and housing. Full-floating, as the term implies, means that the axleshaft doesn’t carry vehicle weight–hubs and axle housings do.
How does a floater rear end work?
In a full-floating axle, the axle is not attached to the axlehousing at all; it is allowed to “float” inside the axlehousing. A tubular shaft is mounted to the end of the housing and acts like your front spindle, only it is hollow to allow the axle to meet up with the wheel assembly.
One of the benefits of upgrading to a full-float axle is larger axle shafts. Bigger is always better and when you’re running big tires you’ll need big axle shafts too. A full-float hub allows for up a 40-spline, or 1.75-inch axle.
How do I know if my axle is full float?
For a full-floating system, the axle shaft only serves to transmit the rotational torque from the differential out to the wheel. It does not carry the weight of the vehicle as a semi-floater does. On a full floater, a spindle is attached to the outer end of the axle housing.
How do you measure the axle length of a 9 inch floater?
How do I measure my axle?
Hook your tape measure on the outside of the hub where your rim touches your hub.Measure across your axle to the exact same spot on the other side. Do not measure to the back side of your hub.
