Live Axle Rear Ends

With this design the axle shaft is a large diameter, thin wall tube and becomes more of a structural member. The shaft is splined in the center to engage the spool and splined on both ends to accept a splined flange on each end. Both ends have a threaded area for the flange retaining nut. Most live axles use a single tapered roller bearing on each end, which must be preloaded with the flange retaining nuts during assembly. This design is most commonly found in Top Alcohol and Top Fuel , dragster and funny car applications.
