Installed BC coilovers.. consistent popping noise

Hello all. Recently, I installed BC Racing BR series coilovers. They ride amazingly and achieve the perfect height I want for a daily. Only issue is that they pop (in the front) pretty consistently. I knew I needed lower ball joints so I replaced those today. Even after replacing those, I still hear the pop. It's pretty much all the time. Here's what I've looked at so far:

1. I've inspected the tightness of all the bolts relating to what I replace. Everything is at torque spec for the part (using the factory manual).

2. Adjusted front pre-load multiple times (recommended is around 5mm, and that's where it's at right now).

3. Tightened the collars on the coilovers as much as humanly possible.

Here's what I noticed:

1. the outter tie rod ends have a bit of seepage from the joint around the top of the rubber gromet. Could the issue be tie rod ends?

2. Even with the preload set to manufacturer recommend specification, the spring can still be twisted with relative ease and moved back and forth (very slightly) with a good bit of force.

The current situation is midly frustrating, any advice on what to do next would be greatly appreciated. Thanks for your time
