2012 LR4 Slow suspension leak...?

[Ruper]

Here's the o-ring kit for the three valves. I am waiting to rebuild my front, as I have the front leak down in 48 hours. Checked the bags with soap and water no leaks there. Pulled fuse 26 and front right went down 30mm, FL 10mm, Right rear 10mm, LR 10mm.
So pretty sure its these babies:
