Ford Bronco Rear Axle Vent Hose Routing Diagram - Correct vs Incorrect

This schematic compares two routing methods for a rear axle vent hose on a Ford truck/Bronco chassis. The left panel, labeled "CORRECT," shows the current vent hose routing along the left-hand frame rail: the hose attaches to the axle vent fitting (secured with a clamp and spacer) and routes upward to the frame rail, where it is held by a clip with a cap on the vent hose end. The right panel, labeled "INCORRECT," shows the old vent hose routing to the cross-member aft of the rear axle, with the same components (clip, cap-vent hose end, hose, clamp, vent fitting, spacer) but with the capped hose end secured to the rear cross-member; a dimension of 11.25 (presumably inches) is indicated for the cap/clip position along the cross-member. Both views indicate the front-of-vehicle direction with arrows. A reader can learn the proper placement of the axle vent hose, routed up the left frame rail rather than to the rear cross-member, as well as the hardware involved: clip, cap, clamp, vent fitting, and spacer. This is useful for diagnosing water intrusion or axle venting issues and for restoring the vent hose to factory-correct routing.
