It's very common. The seal and or the shaft is probably bad. I've replaced mine 2ce in 5 years.

2 in 5 years? Be sure you replace the bearing also there. That is most likely the cause of 2 seal failures.

Also swap to the dexcool antifreeze. It contains NO silicates like the green stuff. The silicates leave deposits that can eat at the seals.

I replaced the bearing once. :naughty:
How cold can Dexcool get? I ride cold and have tried a lot of coolants. Polaris -52 premix is the only one that doesn't turn to toothpaste overnight so that's what I run.
