deffinately a wheel bearing, jack the car up and try to wobble the wheel from top to bottom, if there is a bit of play it may be this, also if u spin the wheel u might hear it, use only timkin bearings, around £50 but a good set, everything comes in the kit and the bearing races are easy to get in, just remember to pack the bearing correctly with bearing or a thick clean grease before refitting, this doesnt mean dip them in grease, put some grease on your hand and working with around 3 bearings at a time press it into the grease, keep doing this till it comes out at the top and do this all the way around, refit and remember they are tapered bearings so DO NOT overtighten the drive shaft nut, use a torque wrench, sorry i cant remember the torque. also when splitting the ball joints on the hub it helps to take the small rubber bump stop out from underneath the top suspension arm and ramming a screwdriver in there to take the pressure of the suspension cone, this should do the trick if not message me
^ um... please read the rest of the thread
