Very Squeaky OME BP-51

Has anyone had any luck fixing squeaky BP-51s?

I've had my full BP-51 suspension since October 2022 and they have been terribly squeaky since I got them. After talking with ARB, they replaced the upper control arms and rear leafs. I had them replaced in April 2023. This seemed to fix them temporary, but a few months later, the squeaking returned. The local off road shop said it was probably the the polyurethane bushings rubbing in the UCAs but ARB thinks it's probably the spherical bearings that are the issue.

Because both the bushings in the UCAs and the spherical bearings are enclosed and neither can be lubed without disassembling the system, I'm looking for any help I can get.

I've watched a video on YouTube where someone replaced their spherical bearings, but it sounded like some of the squeaking was still there. https://www.youtube.com/watch?v=CJte-44HPfI&t=1s

Here is what my suspension sounds like. Any suggestions for how to fix it? I ready to have a truck that doesn't sound like it's 20 year old.

So I have loads of noises from my truck, mostly a daily but has seen some off road miles. But it's still like 99% on road and 1% off road.

Some guys are lucky and some aren't with noises, it's a huge pain for me to keep my truck relatively noise free. Constant maintenance which sucks to be honest.

Your front shock bearings need replaced. This is first and foremost. These are the spherical bearings ARB is mentioning. It's a plague on most aftermarket shocks, I've been lucky to get 10k out of a set. Better lower shock bolts are known to fix some of the issues with shocks like King and Fox that use misalignment spacers. Not sure if ARB uses these, but you can use 4runner bolts that don't have a weird step down shoulder part way through the bolt.

Doesn't look like the ARB UCA's are serviceable, they are a sealed X-axis bearing/bushing. Shocks take about 10 minutes to pull off (once you get the truck jacked up and tires off), but UCA's take much longer. I would start with the shock and see what happens.
