Thought I'd post an update.

Did another inspection and took it for a drive. Upon the first undulation in the road I felt a hard return. Keep in mind I was only going 5-10 mph where the brick road I'm on joins up to a slightly high asphalt. Well, the next 3 miles I drove the front end felt brittle. I pulled over and took a look underneath. Both lower springs now have a massive gap like the one I posted initially on the drivers side and very strangely the front end is sitting a tad lower with almost a tucked wheel look. I also found splatter on the side tyre wall of whatever fluid is leaking.

I drove home gingerly and now waiting for Sept 21st for when it's booked into an independent.

I will say that Oakmere did reach out after me sending them the pics. They advised I should bring it back to them as they feel it just needs a cleaning and perhaps a top up on grease. I've explained I did that and seeing as it's all supposed to be new from last month, I explained that to me it seems something is very wrong in how it was installed. Waiting to hear their response. The question is am I better off cutting my loses and paying yet again for the kingpins to be done correctly....
