A vehicle wheel end assembly

摘要

A vehicle wheel end assembly includes a sleeve member that allows air to be vented from the wheel end while significantly reducing venting of lubricating fluid. The wheel end includes a hub that is driven by a gear assembly. Lubricating fluid is stored within the hub to lubricate the gear assembly. Air pressure that builds up within the wheel end during vehicle operation is vented from the wheel end assembly via a vent path. A sleeve is installed within the wheel end to block the lubricating fluid from entering the vent path.
