Do they worked good or are lots problems?

Mine work great! They are a great safety upgrade and the fact that there is no maintenance is a real plus.

When installing, pay very close attention to the instructions. You will have to drill and tap the housing to install a bolt that holds the hubs in the axle housing. Be VERY careful to follow the instructions as regards 'where' to drill/tap. Don't ask me how I know....

Outside brakes are a must. If an axle breaks the factory drive line brake becomes useless as a service brake.

I installed some last winter. Great safety improvement. No more leaking axle seals on to your outside brakes. The replacement bearing is a common item.

Albert,

What Mike says about brakes is good advice but really has little to do with floating hubs. Or maybe I misunderstand his point?

My safety comment comes from the fact that these hubs eliminate strain on the axle, so there is less possibility of snapping an axle. The hub carries the weight of the car, not the axle.

Also, should an axle snap you don't lose the wheel.

I've only ever seen one rear axle break and that was 1/2 way on the taper, no bearing style was going to stop that wheel from coming off.
No doubt there is several designs in floating bearings, I removed the set up on one of my T's as over the years the rear wheels slowly gained camber and looked like the housings had bent from the rear.

Have seen a few broken axles on tours.

IMO most could be attributed to bad wheel hub taper, or loose wheel by letting the axle nut get slack allowing the wheel to rock on the taper of the axle shaft outboard of the bearings. Or perhaps re-using an original worn axle with bad taper and/or wear from decades of use.

Typical busted off axle @ taper, note the wear patterns on the taper.




This one, with a replacement type of bearing,
still broke at the taper of the axle shaft.







While floating hubs relieve axle stress by design, there can be compromise of the wheel hub fit on the taper of the axle.

Using only a very good or even new wheel hub, and a new axle, IMO, likely provides the most assurance against typical axle failure.

There is another significant plus to floating rear axles. You can use an axle which is too worn to run Hyatt type roller bearings. As long as the taper and the keyway are good, a worn journal on the outside end is in-consequential.Deduct the price of a pair of new axles from the cost of the floating hubs, and it is not a bad deal.

Jerry,

I guess in the case of an axle break the factory brake is useless no mater the type of hub. I claim O.S. brake are a necessity because with safety hubs, the car doesn't fall to the ground halting momentum. Safety hubs will free wheel.

Mike, actually the service brake will work if the axle breaks, no matter whether the break is on the taper or inside the housing.

The floating hub assembly is captured inside the axle housing - it cannot slide out unless the lock bolt is loosened.

The brake drum, wheel hub, and wheel bolt directly to the floating hub assembly. So even if the axle breaks, the hub+wheel+brake drum all remain securely in place.

I would encourage anyone who has doubt or questions to visit texastparts.com and read the installation guide. The guide is well written and illustrated.

I do agree completely that supplemental brakes are necessary in today's traffic, especially in urban areas.

Cliff
