I was wondering if someone can tell me if there is any periodic maintenance that needs to be done on the 'bearings' in beach wheels. Does one wash with soapy water and spray with a lubricant that does not attract dust?

My wheels are getting progressively noisier under the load of the boat -although at the end of the day, after a few beers, it does not seem quite as loud (a bit of sarcasm there).

Thanks
