The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Front axle fluid leak that appears to be from the end of the axle vent hose.

Recommendation/Instructions:
Increasing the inside diameter of the vent hose will help prevent the lube from being forced out of the hose during normal venting. Replace the existing vent hose with a section that is 5/16" (8 mm) inside diameter and of the same length as the original hose. Use a worm gear style hose clamp to retain the hose to the housing and also the vent cap to the other end of the hose.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
