I've never dealt with CV Joints, so I don't know what sounds make. Mine
are original. The bearing plates, at least on my Bonneville were just a
yellow plastic ring with ball bearings between the two rings. From the
side edge you can drip oil in throught the side to oil the ball
bearings. At least I was able to.
