Hi all, please help.....i have had a metalicy (is that a word?) noise from the right front wheel which i assumed would be the brake caliper loose... today the steering wheel is jumping about (vibrating) so i got round to looking today and the braakes are fine but there is lot's of oil where the hub is (where the circlip is around the nut) is it poss that my wheel bearing is gone or going ? and this could be the cause of the afore said problems ?????? please help, and if it's a yes are they easy to change ??
