It was a serious Q, if they indeed work loose why didn't they also alter the design of the pin ? and talk about the pin if excessive heat was used for sure the metallurgical capacities have changed.
Fair comments both... Looking at it, there isn't a simple way to redesign it. I guess it would be possible to include a lock nut in the bottom of the damper clevis, but that might compromise the overall strength of the part. As for the heat altering the characteristics, completely agree. Luke told me that the wishbone pin is fine - the steel didn't get hot enough to cause problems, but that the old 'good' damper clevis shouldn't now be used, as it could well have different properties due to the heat

A simple solution to secure the pin is a metal plate between the damper support body and the wishbone pin, 1 side you knock downwards the other side upwards.
I understand a car manufactor prefer to use Loctite as there is no washer one can forget to add as the Loctite comes with the bolt but there is no need to use it on a Caterham.
