***Only applies if you have the SYA Kit on your rig*** I mostly use my LR4 off-road and over the years I've developed squeaks, all of which I've been able to fix. One developed about a year ago that I could not figure out but it had the same signs as a bad sway bar bushing but it wasn't. Every time I'd hit a slight bump the front end would squeak and it progressively got worse. I found that it would not make a noise if I lifted the vehicle and would drive over a rough road, it was weird...well I found the issue and thought I'd share how I fixed it.
There is a round metal disc on the top of the airbag that over time will rub against the low end of the front SYA spacers which creates a super annoying squeak. By removing the disc you can file it down so that it'll no longer make contact with the spacer. Won't be hard to identify as you can see the wear points. Then put it all back together, throw some grease around it for good measure and there you go.
I have confirmed this being the issue on my friends RRS with the same spacers who also off-roads it a heavy amount... So before going crazy and buying new control arms or sway bushings you may want to check those spacers first because it only costs a little effort to fix.

Rounded off disc, fixed the problem:
