• Product Introduction 24.B90ZB18S-01090 Axle Shaft Oil Seal is a rotary sealing gasket mounted on the rear half shaft of HFC light vehicle axle assembly. Its flexible lip stays in close contact with the rotating axle shaft, preventing gear lubricant from seeping outward while blocking silt, rainwater and grit from entering the gearbox housing. This aftermarket replacement part addresses slow oil seepage, brake drum contamination and premature wear of internal differential gears caused by lip aging, spring fatigue and shell deformation of old seals. Keeping the axle lubrication system sealed helps avoid unexpected breakdowns for small logistics and rural delivery vehicles.

  Product Advantages Formulated with high-quality nitrile rubber, resisting swelling and degradation when exposed to gear oil. Built-in circular spring delivers consistent radial tension for the sealing lip. Stamped metal outer shell maintains stable positioning after being pressed into the axle housing. Every seal undergoes pressure cycling testing before packaging, precise dimensions to match the shaft diameter and reduce installation difficulties.

FAQ

Q1: What common error can damage the lip during oil seal installation?
A1: Sharp edges on the spline or shaft corner will nick the lip if not protected properly.
Q2: What will happen if axle housing pressure cannot release normally?
A2: Internal pressure buildup pushes oil through the seal and creates persistent leakage.
Q3: Can a slight oil stain around the seal prove the seal is defective?
A3: Light residual oil film is normal; continuous dripping marks indicate sealing failure.
