hiya
As a side note , don’t know how similar the wishbones are , but in my D3 there is also a form of bumpstops incorporated into the wishbones , the small white bit in the LH pic
have seen when some fit new wishbones they don’t load them first, causing the bushes to twist and eventually fail considerably quicker

its fairly likely not a replacement part issue but fitting ie feed pipe connection
apologises , thought I had put a pic up,
2nd pic, left hand one is the pushfit , RH is the Voss connector , also a closer pic of the front valve block incorporating the pushfits
on the rear valve block there is a pipe that comes out the back, with the push fits it’s was a dream as so easy to simply push the pipe in, with the voss connectors and the small olive normally have to remove the spare wheel , get underneath and get access with a spanner from there
Indeed, alas don’t know what type of fitting these struts have , but know when I first had mine there were a lot of leaks and mainly on fittings

which ever first time fit is a guarantee later are unfortunately risky as they all work on compression,and once compressed it might not fully again, a bit of rtv sealant can help with that
must admit I replaced the entire strut ,as I didn’t want to mess around and to honest didn’t know what was inside at the time
later found it is has like the Mc Pherson type struts
When I fitted pipe connections I did apply just a few wraps of PTFE On the threads as I was worried if too much was put on some of the plastic parts , ie , valve blocks it would possible cause a split
then straight after used some soapy water , had issues with the voss and sometimes the pushfits if the pipes weren’t clear of gouges or marks
Hi @jamesmartin
hope all is well
this is what I put together to find leaks, I don’t think there wasn’t one fitting that wasnt either cross threaded or leaking
found using a hand vacuum pump that u normally use on brakes very handy , including to test valve blocks to ensure the O ring seals were doing there job and not letting by , all 3 x valves blocks were faulty
saved a lot of time being able to test components before fitting them onto the disco
hope this will be useful to others
Did made sure I tested the equipment first before using it as I didn’t want a false reading

we at least up till now doing very well thank you ,lol you have more kit than i do
Good to hear ur keeping safe and well buddy
Who me, never, just utilised what I already had, well that’s my excuse , lol
made life a lot easier by being able to test each line one by one, by capping them off and pulling a vacuum first then putting them under pressure , got caught out on one , as when I moved the pipe the connector leaked , found the end of the pipe was rough , so cut the end of the pipe off square and all sorted
Think it was having the mindset from my plumbing/ heating days of testing underfloor heatings systems, gas pipes etc

Like that.
Yes, same principle as plumbing, any imperfections near the joint are a path for a leak. Fine grit wet and dry might take out an small scratch but fresh pipe better if there is enough spare.
many thks
Also used some plastic pipe cutters that I still had perfect for the job , inc using a smear of silicone grease , marking the depth of the fittings on the pipes so I knew the pipe had gone in far enough
was like a xmas moment when I found a roll of emery paper in the shed , yeh i know , lol
yep, am a sad old bit, lmao

I have ordered a set from Island 4x4 which came yesterday and are being fitted today. Fingers crossed... 4th time lucky hopefully.

Check it with some soapy water in a spray bottle. Bubbles = leaks. Put some air in the bags before you drop the vehicle back down too

So far so good. The ride was much better yesterday after the new struts had been fitted. There doesn't seem to be any leaks and it hasn't dropped over night.

You’ll peek out the window at it for a week or two until you trust it
