OME UCA0005 upper control arm bushing questions

Hello all, I'm getting everything ready to install new OME upper control arms and wanted to check with those that have them. When I took them out of the box, the metal sleeves in the bushings slid right out. I'm not familiar with these GIIRO bushings, but I expected the metal sleeves to be more of a press fit, but mine just fall right out of the bushing. Do the sleeves and inner bushing need to be greased when installed, the same way polyurethane bushings are? TIA

 

I have the OME UCA's on my 4Runner, and the sleeves are loose and will slide out (normal). I would add just a little bit of grease to the sleeves on the install
