Kia Sportage Axle Shaft Seal Replacement Cost

Many vehicles never experience and axle seal leak. If one does occur it would most likely be on a higher mileage vehicle.

Axle seals leaks are most commonly diagnosed by visual inspection. In cases where the cause of the leak cannot be pinpointed, dye or tracing powder can be used as an aid in locating the leak. Prior to replacing the seal, the axle shaft should be inspected for up/down movement in the housing. Excess movement would indicate worn internal components. Any worn component(s) should be replace prior to replacing the seal.

A worn axle shaft support bearing can cause premature failure of the axle shaft oil seal.

To replace an axle seal, the axle must be disconnected from the transmission/axle. The seal is then carefully removed from the housing - sometimes a special puller may be required to remove the seal. It is very important not to damage the housing when removing the old seal or installing the new one. The new seal is then seated in place, perhaps with a bit of sealer around the outside edge where it meets the housing. Prior to installation the flexible material should be coated with the appropriate fluid. The surface of the axle shaft that the seal rides on should also be inspected for wear or other damage, a damaged axle can ruin the new seal.

Gear oil can leak onto the brake shoes from a worn axle seal. Brake shoes contaminated with gear oil should be replaced.

A quick visual inspection of all axle seals should be made while the vehicle is raised on a lift for a routine service/inspection. A leaking seal should be replaced to prevent internal component damage due to fluid loss. Always use the correct fluid type when topping of transmission/axle fluid after seal replacement.
