Topic: locking rear axle hubs

  I've seen a couple kits on Speedway that keep the hub from rolling away if you break your rear axle...are they worth it...do they work?

  There are two different types. One type goes inside the hub with studs that go through the backing plate. The other is a bracket that bolts to the backside of the backing plate and uses the wheel cylinder bolts to hold it. These brackests have a lip that goes over the ridge on the brake drum. Either one is a good idea. If you have ever seen a hub and part of an axle come loose it is not a pretty picture. I saw this happen to a guy with a 34 cabriolet and it tore up the rear fender and quarter panel.A very expensive repair.

  That is why you should re-pack your wheel bearings frequently and check for wear on the axle housings. The flexing caused by worn housings causes axle failure.

  In addition to TomO's advice, be sure to carefully check the inside corners of the axle end keyway. Most axle failures occur when the end breaks at that point. The cracks are the result, in most cases, of the failure to retighten the axle nuts after driving a few miles following the removal of the hub for service. This is particularly true if the axle ends were not completely cleaned of grease and dirt before reassembly, and were dried before the hub was put in place. Any cracks or distortion of the keyway requires axle replacement. The safety locks usually keep the hub on the axle housing, but loss of control is still possible at hiway speeds.
