31N-04075-JH Rear Wheel Oil Seal Housing is a sturdy mounting retainer for rear axle oil seal of JAC HFC light truck. It secures the hub oil seal in place and forms a reliable barrier that stops lubricating grease leaking from the rear wheel hub, while preventing muddy water, dust and grit from invading the wheel bearing assembly. This aftermarket replacement housing solves continuous grease leakage, oil seal offset and premature bearing damage caused by deformed mating surfaces, corroded threaded holes and scratches on old housings. Stable sealing performance protects wheel bearings from abrasive contamination and reduces roadside breakdown risk for delivery trucks operating on muddy rural roads and rainy working conditions.

Product Advantages Fabricated from high rigidity cast steel with anti-corrosion surface treatment. Precision machined inner bore ensures perfect fit for the oil seal and uniform compression of sealing lip. Evenly distributed bolt holes allow balanced fastening force without warping. Each housing undergoes flatness inspection and dimensional verification before packing, OEM hole layout and outline for hassle-free bolt-on fitting without extra modification.

Applicable Models Fit for JAC HFC series light-duty commercial trucks, widely used for urban distribution and short-haul cargo transportation.
