Cheers guys, just what I wanted to hear! BTW Odd Job I did know they're just the dust covers
but someone may not and I didn't make it clear.
So renew all , including dust caps, seal and retaining clip as I'm at it or just seals - spoil a ship for happney of tar springs to mind ,especially as it's a bugger of a job anyway. But seriously OEM or genuine replacement, DS has both but as above, while I'm at it?
