Ok so what do I do? Do I need the metal sleeve to install the poly bushings? Only reason I ask is because there is a lot of moving back a fourth on the axle bracket where the bushing goes
Not sure there's even such a thing. Of course, I've never run poly bushings on my JK so I couldn't say for sure. For the most part, you just install them and go. I have never really found them to be a good fit and between that and them squeaking like a banshee, I prefer not to use them.
