Gladiator rear axle leak: parts, repair time and campaign 26A

Check campaign 26A before buying parts

Jeep’s customer satisfaction notification 26A covers a right rear axle-shaft oil leak on certain 2021–2022 Gladiators. It does not include every truck from those years. Ask a Jeep dealer to check your VIN and whether the campaign repair is still outstanding.

A leak somewhere else needs its own inspection. Tell the shop which side is wet, when you first noticed it and whether anything has changed in the way the truck drives or brakes.

Which rear axle part numbers are listed?

The campaign lists two right-side axle assemblies. The build codes matter: confirm them against the VIN and the axle actually installed. These are assembly references, not interchangeable seal kits.

How long does the axle repair take?

Jeep’s owner letter estimates about one hour for this campaign repair, plus time for the visit. Its dealer labor table separately lists 0.2 hours for inspection or 0.7 hours for axle replacement; those are alternative operations, not a total to add together.

Use that as a reference for the specific campaign job. A different leak, a modified axle or additional repairs needs a separate estimate. Confirm parts availability and pickup plans before leaving the truck.

Is this a reasonable driveway repair?

The campaign does not call for special tools, but it does involve brakes and axle removal. Jeep warns against hanging the caliper by its hose and reusing the axle-retainer nuts.

Having a jack and the right part isn’t the whole job. You need safe vehicle support, the proper tightening tools and enough experience to check the work before driving. If those are missing, we recommend using a shop. A damaged brake hose or loose hardware is a much bigger problem than the leak you started with.

What to do next

Have the leak identified before planning the next trip. If braking has changed or the truck feels unsafe, arrange transport instead of driving it to be checked.

For an eligible campaign repair, start with a Jeep dealer. If your truck is outside the campaign or needs other axle work, call our Salem shop and tell us what you’ve found. We can discuss the next step without asking you to guess which part has failed.
