2019 Jeep Wrangler Axle Shaft Seal Replacement Cost

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.

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.

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.

All related components should be inspected and replaced as necessary along with the axle seal. replacing a leaking seal without repairing a damaged housing and/or axle can result in a repeat seal failure. Always use the correct type of fluid when topping off the level of the transmission/axle after seal replacement is complete. It is also important to coat the flexible part of the seal with a bit of fluid prior to installation. A “dry” seal can be quickly damaged as when axle first begins rotating after replacement. Over time the transmission/axle fluid will keep the seal lubricated but it can take a bit of time for this to happen - hence the prelubrication.

Repairing your own car is an extremely rewarding process that can also save you money. But before you dive in, it’s important to be sure the issue has been properly diagnosed. Seemingly obvious symptoms can lead the inexperienced down a rabbit hole of replacing parts that don’t fix the problem. Proper diagnosis can save more money than guessing at what’s broken! If you're unsure you have the right tools or experience to diagnose a problem, consider reaching out to a RepairPal Certified Shop. In almost all cases, some portion of the braking or suspension system will need to be disassembled in order to remove the axle and gain access to the seal. A special tool may also be required to remove the axle from the transmission/axle.
