At Man A Fre we have a supply of Toyota Land Cruiser full floating rear axle assemblies. For most situations, the semi-floating rear axles, as supplied for the US market, are just fine. However, in the rest of the world, Toyota offered heavy duty full floating rear axles for Land Cruisers that are used for towing or hauling heavy loads.
Why a full floater? Very simply, the semi-floating rear differential as found on all 40 and 60 series Land Cruisers sold in the US market use a rear axle that keeps the axles in place by holding them in with “C” clips in the differential unit. The weight of the vehicle is supported by the axles, so in turn, in a single roller bearing located at the outer end for the axle housing.
On a full floater, there are no “C” clips holding the axles in, instead at the end of the axle housing are spindles similar to the ones on the front axle of the Land Cruiser. These spindles support wheel hubs that have two tapered roller bearings in each hub. The bearings are adjusted with a nut just like the front wheel bearings and the axles are held in and onto the hub with six studs, washers and nuts. This system makes for a much stronger rear drive axle setup for those that need or want the extra load carrying potential.
