Linear Profile Bearings - Clatter Noise, Maintenance?

Regards the weight making them quite down then again thats not unusal and they will move more freely also and take that notchy feel away.!

Good idea, if you have a decent set of weighing scales this might show a difference between the one you stripped down and one of the quieter ones.

Really not worth the effort has they will be fine and besides there's very little can be done about it if they are worn out because the body will be worn not just the balls.!
Even if they are worn they will still be miles better than the cheap round rail bearings unless completely knackerd which they don't look or sound to me.
