Differential casing: replacement and selection

When and why it is necessary to replace differential casing

This component has no exact operational lifetime. The differential casing should be replaced at mechanical damages or its surface deformation. Moreover, spline connections of the part often break due to corrosion.

Component deformation often occurs due to defect of the bearing or its mounting seat wear-out. Sometimes, component integrity violation is the result of extreme driving style. Corrosion damages of the differential casing are the result of moisture effect.

Damaging of the part is usually pointed out by screeching or humming from the differential, which appear at cornering. Driving is impossible if the component is totally broken.

Replacement of the differential casing should be performed at a service station. First, this will require disassembling of the gearbox or the final drive gears and the differential. Specialists will also inspect other gearbox elements, and perform their replacement if necessary.
