It seems for the past 2 summers I've had some seepage from the shaft seal in the Aluminum XS auger gearcase. The level remains at the fill hole though so its very little. I've seen a post by Snowmann saying to lower the level by raising thewheels and letting some out. Has anyone done this and had any issues? I figured it would eventually stop when the level get low enough. Seems like pressure during the warm weather is the cause. Thanks GP

I have the exact same issue on my ST926LE (926001) with an aluminum XS gearbox. There is a leak at the rear shaft seal after each use.

Anyone knows why the two lower side seals are reliable while many people have a leak issue with the higher rear seal?

I needed to add 2 ounces of L2 to bring the level back to the fill plug. Should I replace the rear seal?

Is L3 grease thicker?, would it help to replace the original L2 by L3?
