Hi, does anyone know if it is possible to replace the bearing on the rear hub, failed mot due to play, my friend that fixes my car has tried to find someone that supplies the bearing but has so far drawn a blank, waiting for lexus to get back to us, seems like we can only replace the hubs, anyone know of another make or models bearing that would fit???? he's got a tool he bought from japan that removes the bearings from hubs without causing damage :)
