mysterious squeak

[cosmo]

Hi,

I have some weird squeaking noise coming from the rear right.
I replaced recently:
Shocks + shock mounts
trailing arm bushings, subframe bushings (initially put in poly bushings but they were squeaking despite greasing them generously, maybe they weren't at fault after all since the squeak sounds very familiar, but this time it's only coming from the passenger side)
spring pads
sway bar end links

Still, the squeak won't go away.
It's mostly noticeable when taking off from standing /low speeds.

Any clues?
Would hate to do subframe bushings a third time this year
Thanks so much!

this sounds like spring pads. I had the original spring pads in and put new springs on and they squeaked like fuck. Thought it was bushings and re-replaced the trailing arm bushings back to OEM rubber, having put poly in earlier. Still squeaked like that and I replaced the spring pads and put a bunch of anti seize where the spring contacted the pads and it went away. Was a gloriously quiet first drive
