How hard is it to change the bearings in the rear wheel of a specialized fsr xc comp? They are the sealed type not the cup and cone type, every bike shop i have phoned won't fix it on the day for me, they say i have to leave it with them and collect the next day but that is a real pain having to drive to Dublin twice from carlow or waterford twice (plus the traveling cost)

Its easy to do it yourself. If you have all the right parts you can do it in around half an hour.
First of all get the bearing numbers of the bearings fitted to your hubs. These are specific to each and every bearing. You will need these numbers when you go to order new ones. Not all bike shops will stock every kind of bearing so I recommend ordering Enduro bearings on CRC first. Just get the 2RS bearings, they're cheap and work just fine. Don't bother with the fancy ceramic ones as they cost a fortune and make fup all difference anyway.

Order the new ones first before you remove the old bearings. If its only a little bit of play in the bearings then you can ride them to death. Don't worry about damaging them as they are already fooked. You won't damage your frame or hubs either unless they are literally hanging out of the hub and rattling all over the place.
The bearings are simply pressed into the hub. To remove them you must remove the axle first. Then simply tap out the bearings from the opposite side of the hub. Use a broad flat bladed screwdriver or a piece of soft aluminium. Tap them out slowly and gently, one tap at a time, going around the steel outer edge of the bearing. If you tap the inner edge there is the possibility that you could tap out the inner bearing race / cage and end up with half a bearing stuck in the hub.
Once the old ones are out. You simply press the new ones in. You can use a suitably sized socket or the old bearings to do this. Again, you press against the outer edge only. If you press the inner edge you will permanently damage the bearing and your back to square one. Use a soft hammer or wooden mallet to gently tap them in to place. Again, go slowly and make sure they go in straight and true or you could damage the hubs.
There are specific bearing removal and press tools available to make this kind of work much easier and quicker but they cost anywhere between â¬100 - â¬150 for the removal tool and the press can be around the same.

So basicaly it's just like changing a car wheel bearing but on a smaller scale, thats ok then, thanks for the help.
just one more thing though, the axel has two end caps which are held on by two grub screws (i'm sure you know all of this anyway lol) when i removed the end cap on one side i was expecting the axel to side out of the other side but it didn't, it apears to be stuck in, is that normal? (small tap with a hammer maybe?)
