There are kits that convert your axles to press on wheel bearings so you no longer use the C clips on the ends of the axles to hold them in.
There is a bearing housing that bolts on the end of the housing. I think you need to saw off some of the housing end to install the kit.
They are prone to leaking and not a good deal for a street car. It's a cheap way to convert for drag racing safety. If an axle breaks, the wheel won't fall off the car.
