Default Squeaky Rear Suspension Problem

This is an update from previous posts.



I've got Whiteline bushings for my rear upper control arms and rear trailing arms.

Installation was done as instructed, moly grease the inner bores and faces and contact surfaces.
Everything was torqued with the suspension under load to curb load.


Watch the video for the level of squeaking and creaking from me bouncing on the trunk, this was after a test drive right after installation.



I don't know what else to do.

I just finished doing a very similar job and also had a very similar sounding creaking. Today, I unbolted one end of everything I touched and moved everything by hand. Turned out to be the kartboy sway bar endlinks. The endlinks were the aboslute last thing I reinstalled and it was getting dark so I skipped the torque wrench. While I did quickly regrease them, I'm certain the creak came from over torquing.

My endlinks are spherical bearing ones from Perrin, and I torque absolutely everything to a T every time, so I don't see how it could be over-torquing on my end, I basically have been following the torque numbers from the Subaru service manual.
These bushings companies haven't given me a different torque setting to use so I just go with what Subaru says the torque should be, I don't see why they should be different and yet, squeaking more than a 30 year old truck
