rear wheel grinding noise

I'm hearing a grinding noise at the rear wheel lately.
It seems it's getting louder every time I drive the car 
It's one "grind" in one turn of the wheel.
It's not there when braking or accellerating, only when 'rolling".
I would think it's the brake disc, but I don't feel anything strange while braking.
What do you guys think?

Sounds like it could be the wheel bearing

almost deffo the wheel bearing, normally the drivers side, for some reason the 'boffins' at ford made them out of recycled tin cans then plonked 2 tonne of car on em, its a common fault..........

when you or a garage put them on make sure they're torqued to the specific amount, it is high about 200lb from what i remember, failure to do this WILL result in them failing a few months down the line...

Make very sure that the hubs are not worn,both bearings each side should be a firm press fit,if not there is a severe chance of premature failure.

It is 200ft/lbs and the further advice is to have them re-checked after a couple of hundred miles as they have been known to work loose even with the correct torque and loctite.

I'm almost done on one side but I can't get the brake caliper to go in.
I realized I left the parking brake on while I removed the caliper.
Any ideas?

The piston should wind in clockwise

The rear pistons WIND back. You cannot press them back as with the front ones and ideally you need a 'wind back tool' which can be aquired for a few pounds. It is possible to use a pair of long nosed pliers BUT the correct tool makes life far easier. Have a look at This page from the Draper catalogue. Works a treat.

Sorry, should have said....'The piston should wind in clockwise while applying pressure'
The item Simmo is referring to is called a 'brake cube' & if you search ebay, is for sale for as little as £3.99. But if your in a hurry for one, then a good local motor factor should have them in stock

when replacing rear pads on my mk3,i use a g-clamp and a pair of curved jaw mole grips.the g-clamp puts pressure on the piston and the mole grips wind in the piston,after a few turns i retighten the g-clamp to keep the pressure on the piston,i do this until the piston is back in the caliper install new pads,refit caliper,..works everytime .
