Why dont you have a go at servicing the bearings.
Its easy to do mate.
If there is no play you could save them worth a try .
Just need a thin knife to slip under the seals they pop open very easy.
WD 40 and a old tooth brush to clean off the grime inside , then pack with grease.
I have done a few with great results.
There is a tutorial some where I used ..
I think the bearings are 6000r
