SV2 Pivot pins

[trr061984]

Just a query really, and wondering if anyone else has had an issue with the pivot pins on the front arms that hold the pivots to the front arms. Never had a problem with them until about 2 weeks ago, and since then, they have come loose, or completely fallen out in about half of the races and heats I have partook in. The irritating thing is that Schumacher do not have any in at the moment, so I am not sure whether the pin has somehow fouled and needs replacing. The other room is fine, and has never been an issue.

Thoughts?
