Located at the rear is the hypoid semi-floating type of rear axle assembly that has a differential carrier formed by casting with a pressed steel cover to keep it intact. An optional limited slip Traction-Lok rear axle is offered, which will work in a normal way under normal conditions but in case one wheel loses its traction, it has multi disc clutch packs and a speed sensitive engagement mechanism to lock the two axleshafts to the supply equal revolving power to the two wheels. Having identifiable numbers on the axle, often found on small metal tag along the cover bolts is very vital for some operations particularly for when replacing axleshafts. Many a time what may be thought as originating from the rear axle may actually be far from the truth, a close assessment is normally warranted before coming to conclusion that indeed there is a problem with the rear axle. The most common sound related to rear axle diagnosis include; road noise, which does not vary with power or coasting, tire noise which is constant with worn or under-inflated tires, and engine and transmission noise that leads to misleading results; filtering these noises require the noting of the engine speed then performing the diagnosis in Neutral. Assembly and general repair about the rear axle need specific tools and critical dimensions, so, operations such as the removal and installation of axleshaft, replacement of oil seal, replacement of bearing, and removal of complete unit for repair or for replacement are more fit for expert mechanics than for do-it-yourself mechanics.
