What Causes Rear Axle Oil Leakage?
1 Answers
Rear axle oil leakage is caused by improper assembly, porous castings, excessive oil filling, damaged sealing edges, and misaligned connection holes. Improper assembly: Incorrect installation of the main drive pinion oil seal. This situation requires professional repair. Porous castings: Bearing housing castings have porosity or sand holes. Replacing the oil seal won't solve this issue; the bearing housing must be replaced. Excessive oil filling: Overfilling of gear oil. Damaged sealing edges: Damage to the oil seal edge during half-shaft installation. Misaligned connection holes: Misalignment of the rear axle wheel hub flange connection holes, causing the half-shaft and wheel hub to be non-concentric, which repeatedly damages the half-shaft oil seal.
