Pre-MOT paranoia is starting to kick in, and something has occurred to me - I replaced a track rod end and the plastic spacer/cup on the ball joint nut was in pretty bad shape, and because the end of the nut was rounded off with rust I ended up having to dig out what was left of the plastic spacer so I could get a socket fully onto the nut and undo it.
So I ended up fitting the new nut with no plastic spacer/cup or washer. Is this a problem that is going to cause the MOT man to frown on me, or is it perfectly ok for that plastic cup to be missing as long as its a new nylock nut ?
If it would cause a fail, where might I get such a plastic cup/spacer other than the terminally slow Citroen dealer ?
