Squeaky suspension

For the past few months my suspension has been very very squeaky, i just took it in to toyota and they weren’t able to fix it, does anyone have any recommendations?

 

In the rear? Need more details. I had a loose spare tire that I thought was squeaking suspension.

 

if its your rear leaf springs then you need this TSB, my 2017 was really bad,, had the tsb done last yr. no squeaks since..

 

Had the same problem, took it to dealer and they told me that one of my upper ball joints hs a torn rubber cover where it takes grease, so it wont hold grease in it. Works itself out and starts to squeak. I'm going to replace it but it sucks to replace an otherwise good ball joint because of a torn rubber cover
