The ball joints in my 1978 300CD are in need of replacement. Can I just press new ball joints into the lower control arm or does the whole control arm need to be replaced? I have read that the control arm must be replacd if the collar on the ball joint is ribbed - and it appears these ball joints are made that way.

Thanks for your patience, I know that to an experiance mechnanic this may be rather obvious.


Thanks

Tim
