    Rwd axle bearings

    FULL-FLOATING AXLE
    Definition - axle bearing is on the outside of the axle housing.
    No weight is on the axle shaft.
    Used on 3/4 ton and larger trucks, and four wheel drive front axles.
    If axle breaks wheel will not come off.
    SEMI-FLOATING AXLES
    Definition - axle bearing is inside the axle housing.
    Weight of vehicle is on the axle shaft.
    If the axle breaks the wheel will come off.
    BEARING STYLES
    Three styles of RWD solid axle bearings.
    Ball Axle Bearing
    Straight-Roller Axle Bearings
    Tapered-Roller Axle Bearings
    Lubricated from differential or packed with wheel bearing grease at time of installation.
    BALL AXLE BEARINGS

    Held in place by metal retainer bolted to the end of the axle housing.
    Seal is inside of the axle bearing.
    STRAIGHT-ROLLER

    Held in place by a C-Clip in the differential case.
    Seal is on the outside of the bearing.
    Bearing is lubed from differential.
    TAPERED-ROLLER
    Held in place by metal retainer bolted to the end of the axle housing.

    Two seals one inside of bearing, one outside.
    IRS AXLE SHAFTS
    Two types of independent suspension:
    Swing Axle
    Single Joint
    Camber changes with suspension travel.
    Independent Rear Suspension
    Camber does not change with suspension travel.
    Two Joints
    Axle bearings are similar to FWD.
    MAINTENANCE
    Use correct lube type:
    GL-1, GL-2, GL-3, GL-4, GL-5.
    Posi-traction differentials require a Limited-slip additive.
    Transaxles may require:
    Gear oil
    Motor oil
    ATF
