If its just a bit of play in the bearings you can open them up and tighten the cones which is a 10 minute job and will get you loads more miles out of them. You just need a 10mm and 7mm spanner for adjusting the cones and to open them up I think its a 15mm spanner. No need to bin them just cause a bit of bearing play... but if you do give them to me cause I need another pair!
