The rear bearings especially get noisy way before they develop noticeable play.
The rear ones are easy to detect by jacking the car up with the handbrake off and spinning the wheels. You will definitely hear the worn one. There should be silence when it rotates, apart from disc brake dragging noises.
The front ones are harder to detect because of they gearbox, driveshafts and brakes adding a lot of resistance. The steering feels a bit loose off centre when they are worn out though.
I reckon it's a rear. My eddy needed a passenger side rear at 90ish K miles. I would advise against pattern parts for the chassis, but obviously go with what ever suits your budget. The rears are very easy to do DIY, but you do need some special tools.....namely a 3/4" drive triple square for the main bolt (I can't remember the size) and a bloody long breaker bar!
