Why Does the Steering Gear Leak Oil?
2 Answers
The reasons for steering gear oil leakage include: penetration of screw holes, oil leakage at the bottom cover, and poor quality of oil seals. Here are the specific repair methods: 1. Penetration of screw holes: Add fiber thread or gaskets at the bolt root for sealing. 2. Oil leakage at the bottom cover: Re-machine the plane and holes or fit a guide tube. 3. Poor quality of oil seals: Replace the oil seals promptly and inspect the bearings and shaft diameters. If necessary, replace new bearings or polish the shaft diameters. Poor quality oil seals can lead to oil leakage at the steering arm, so it is essential to replace the oil seals in time.
Power steering fluid leaks are quite common, usually due to aging seals like oil seals or gaskets that harden and crack over time, causing slow seepage. Another cause is damaged or loose oil lines, especially after prolonged driving on bumpy roads which accelerates wear. Internal gear wear within the steering gear can also lead to leaks. I recommend owners regularly check for oil stains under the car or at the bottom of the engine bay. If steering feels heavier, be cautious. Early detection makes repairs easier—replacing seals or lines doesn’t take much time and costs are reasonable. Don’t delay, as running out of fluid disables power steering, making driving unsafe.
