Final drive leaking oil: what replacement fits my machine?
Expert Answer
A leaking final drive usually means the drive assembly has a failed seal, worn shaft surface, or internal wear that is allowing gear oil or hydraulic oil to escape. If the leak is at the sprocket, hub, or case, the safest fix is often to replace the complete final drive rather than keep topping it off.
