Today I took out my wife’s 2006 Kodiak 450 out of storage that has been sitting for 2 years and the right rear axle seal is leaking. I had it replaced under warranty at 400km and now with 6500 km it is leaking again. It was not leaking last year so I don’t understand why it is leaking now after sitting in storage for 2 years. It was not leaking when I parked it and the oil level is correct and the diff is under no pressure since it has not been running, so why is it oil leaking past the seal. Can anyone shed some light to why this is happening. My 700 has never leaked so I don’t think age is a problem

Thanks
