The 14 HU differential assembly that is used is a hypoid unit with pinion arranged on the cross-car centerline. Drive shaft connection uses a cassette type pinion oil seal, which is an integral part of the pinion flange. Seal cannot be separated from the pinion flange and must be replaced as a complete seal/flange assembly. The axle shafts are driven by the output flanges which rotate on sealed bearings, these assemblies are retained in differential unit by circlips. The differential assembly is filled for life using a thermally stable lubricant. Serviceable differential components include the pinion flange/seal assembly, pinion flange nut, output shaft bearing " O" ring, output shaft bearing circlip, output shaft bearing and output shaft.
