hmmm, i have no faith in well lane.

Get a NEW -31 actuator, take it somewhere decent for a setup.

The actuator when its on the car, should be half a hole out on the arm for the wastegate iirc, this is the preload.

Ie when you offer the actuator up to the turbo and wastegate, you should be able to see half of the hole on the rod end it self, as the wastegate arm should be half visible.

man, thats a hard thing to describe this early in the morning.
