Well
Went for a short drive with the new CVs fitted. Got 400yds and loud bang again..........
Set off for home, and all quiet so carried on with my short drive.
After 2 miles parked up and crawled under.
Right hand side CVs cold and hub/disc cold.
Left hand side inner CV cold.
Outer CV and hub hot!

So either the new CV with 2 mins use on it is defective, or the wheel bearing may have been the culprit all along?
Anyone have any ideas what causes the load bangs?

Anyone have any idea what bearing is in the rear hub of a Corse I, and how difficult to get in/out?
