Suspension Woes Advice Needed

[Error404]

Done up or not, you can still see that the springs aren't seated properly and are at an angle due to being upside down. As above, it won't have caused an issue on the rear but would have done on the front

I can tell you 100% I tried them in both orientations and they fitted better the way up I installed them. With them on the strut in the orientation you suggest as a catch all, the spring did not sit vertically. I don't think it is unreasonable to suspect there is some variation in the H&Rs, considering they were manufactured for many years, the fact that H&R themselves don't even know which way is up, and the fact that I didn't hear a peep out of my apparently incorrectly installed items for over 2 years. The fact that Ray is having issues with the exact same set of springs installed differently suggests that might also have something to do with it, but what do I know?
I still think the main issue here is the inserts concentric ring not being fitted correctly or the strut cap being loose.
