That is consistant with a bad wheel bearing so they should be checked,

is this a costly fix or can i do it myself

thanks neil

Bear with me as I haven't seen a Renault in ions of any kind but I'm guessing it's front wheel drive only and has sealed rear bearings and hub as a unit. If you have anti-lock brakes it may have a sensor in that hub.

If FWD only you can jack up and just spin rear wheels and you should hear the noise. Good bearings are almost silent. They could be expensive and could be difficult and if you think that's it just describe it and I can guess at how to replace it.

Perhaps another here knows the car exactly but let's find out if it's a bearing at all right now -- probably is.

See what you can determine and hit back. If nothing check out the tires themselves as they can do funky things and rotate them and see if sound follows the tire if the case,
