Noise from rear at speed
 

hi all :)

when going down the motorway at say 60 and above i get a low frequency noise, that increases with speed, from the rear, kinda a droning sound im thinking wheel bearings or maybe rear diff making the noise but im not sure, the cars a my 98 uk turbo wagon. with abiut 84k. im gonna check the fliuid in the rear 2moro, if its wheel bearings, how much of a pain to change?

Thanks all

Rich
