My rear left wheel has slight lateral play, ive now noticed that there is oil leaking from the axle behind the rear right wheel.

i have noticed every now and then a metalic screetch from the rear axle which i can only describe as if a ball bearing is between the drive shaft and axle case if that makes any sence lol

any ideas as what needs done to sort this?
new wheel bearing?
new seals?
new axle?
new car?!?

I'd go with bearings. When you get a bearing kit it should come with a new oil seal.

Good luck
