Kenworth T680 Wheel Seals & Bearings (2012–2026) — what we stock

A wheel seal has one job: keep gear oil in the hub and grit out of the bearings. When it fails on a Kenworth T680 you see the stripe — oil slung across the inside of the tire and drum. That's not cosmetic: oil on brake shoes kills stopping power on that wheel end, and a bearing running dry follows shortly after. Seal and bearing work is routine, but only if the parts match the axle exactly — which is why every listing here carries dimensions and OEM/SKF cross-references.

How to pick the right part for your T680

Pull the axle and bearing spec from your paperwork or measure the old parts: seal OD/ID and the bearing cup/cone numbers are the ground truth. Our listings cross-reference SKF, Stemco and National numbers so you can match whatever the last shop installed. Steer and drive axles use different seals — don't assume one number covers the truck. If the drum came off oily, inspect the shoes: contaminated friction material gets replaced, not degreased.

Kenworth T680 Wheel Seals & Bearings — FAQ

How do I know which wheel seal my axle takes?

The number on the old seal, the bearing numbers, or your axle model tag — any of them cross-references to the right part. Our listings carry SKF/Stemco/National equivalents, so match whichever brand the last shop used.

Oil on the inside of my tire — is it always the wheel seal?

On a drive axle with oil-bath hubs, almost always. Confirm the level in the hub cap window if you have one. Fix it promptly: the same oil is reaching your brake shoes, and that wheel end is braking at a fraction of spec.

Do I replace bearings when I replace the seal?

Inspect them: if the rollers and races are bright and unscored and the truck's maintenance is known, repack and reuse is common practice. Any bluing, pitting or roughness — replace. The listing pairs matching cups and cones so you're not mixing worn and new.

Are these seals compatible with the factory hubs on my Kenworth T680?

Yes — everything on this page is a direct replacement matched by dimension and OEM cross-reference for the Kenworth T680 axle fitments listed. Verify against your axle tag or VIN and it goes back together to spec.
