The seals should last for years, and only leak because of a reason. Is it one side or both? There is normally a drain screw near the axle, is it leaking?
A knock to the exposed leg can dent it, or scrape some chrome off, or even slightly bend the leg. Sand can get in there and scratch a seal, but that's unlikely.
Make sure your dealer checks for what caused thge leak and does a complete fix.
