Ditto that advice. A club member had the entire hub fail during a contest and we were able to find parts from eBay and Amazon to get it rebuilt by the end of the contest.

Another good place to buy nearly any AL-KO part, albeit located in Europe, ishttp://www.tauntontrailers.co.uk. Prices are reasonable even after shipping.

Great.
Be mindful of axle nut torque values. Too tight or too loose can waste a bearing very quickly. A spec sheet with the bearing, or online, can show the correct torque value.
Banging it on with an impact wrench is not correct.

...tauntontrailers...

One of those will keep your glider warm in the winter. Luke warm, at least.
