Squeaky bearing?

[Gagakev]

Have had a squeak coming from the offside wheel on the last few outings so before we went this time called our service engineer, he checked and greased all the nipples neccasary and when I pulled away no squeak.
But when I arrived on site just over an hour later, it was worst than ever.
Chap next to me (a vehicle mechanic) said it was the wheel bearing as it is ok when cold but as it gets hotter so the noise increase's.
Can anyone shed any light on this and confirm it could be the problem and what should I expect to pay for a new bearing and should I change both sides at the same time?
Thanks in advance for any help.

Have a look here at bearing kits

The wheel & hub need to come off to investigate the problem, it might be advisable to fit new brake shoes aswell.

For what it would cost i would have both sides replaced for peace of mind, you dont know if they are the original item that was fitted from new

Sproket thanks for the links, they seem reasonably priced and as they have a branch less than a mile from me think I'll use them, cheers.

Forest, no not 100% sure it's the bearing but at the prices sproket has provided think as the wheels have to come off may as well do brakes and bearings even if it's just peace of mind, cheers.
