What is the issue with oil leakage in the rear axle of the Mitsubishi Pajero?
1 Answers
The reasons for oil leakage in the rear axle of the Mitsubishi Pajero are as follows: 1. Incorrect assembly or damage to the oil seal of the main drive pinion. 2. Porosity or sand holes in the bearing housing casting: In this case, replacing the oil seal will not solve the problem, and the bearing housing must be replaced. 3. Overfilling of gear oil: Damage to the oil seal lip during the assembly of the half-shaft. 4. Misalignment of the rear axle wheel hub flange connection holes: This causes the half-shaft and wheel hub to be out of alignment, leading to repeated damage to the half-shaft oil seal. 5. Damage to the inner oil seal of the rear wheel hub: Lubricant is thrown out from the inner wheel disk. To prevent oil leakage in the vehicle's rear axle, first, pay attention to the gaskets. The gaskets between the components of the rear axle mainly serve to prevent leakage and provide sealing. If the quality of the gaskets is too poor, they may not effectively seal and prevent leakage, potentially leading to accidents and oil seepage. Secondly, all the fastening nuts on the rear axle need to be tightened according to the specified torque. If they are too loose, the gaskets may leak due to insufficient pressure, and if they are too tight, the metal protrusions around the screw holes can also cause oil seepage.
