OVERVIEW OF AN AXLE
An axle shaft is the final part of a differential that transfers power to the wheels. Front and rear axle shafts have different construction details. A rear axle mates to the wheel via a flange on the end. A front axle consists of two shafts, an inner and an outer, that mate to each other via a universal joint to allow for turning. Front axles connect to the front wheels via a hub assembly. Factory axle are typically made from a 1040 alloy steel, while aftermarket performance shafts are made from a 1541H or 4340 Chromoly alloy for significant strength gains.
AXLE BEARINGS, SEALS & STUDS
When an axle is purchased, it is beneficial to also install axle bearings and seals and axle studs.
A common reason for axle failure is bad bearings and seals and replacing these is critical.
These parts are inexpensive and will warrant longevity and optimal performance.
