With everything greased, removed shockers, did the drop test several times and rebound springs were still tight. Unscrewed the locking ring and loosened the other ring a few turns, but doing the drop test repeatedly, nothing seemed to change. I have gone both ways by a good inch or more but the rebound spring remains at a compressed length of about 55 mm. I cannot get a gap to appear.
Have I missed something?

Can only suggest there must be a point the stub axle to rebound spring clearance appears with the suspension loaded, i.e. car sitting on its wheels. As you know releasing pre-load on main spring achieves this but stiction can change this quite dramatically.

Suggestions therefore:
Ensure kingpins freshly greased
Ask a friend to sit in driver's seat and bounce if necessary
Try using initial SSL settings according to model and spacer position


Thanks Richard and Peter
I have had another go and slackened off the main spring completely . Then after a couple of drop tests, the rebound spring became loose at last. Re applied tension to the top to give just 15mm of thread showing, drop tests again and the rebound spring is gin tight. Recommended thread gap for a modern plus 4 is 28 mm so something not quite right.
I made contact with Peter B and as he lives not too far away has very kindly offered to pop over tomorrow. What service!
More info when sorted.
