theres a couple different options that i have and i would do. im sure someone will come in here with some different and possibly better ones but...

since they are already off the vehicle you can go get some liquid polyurethane from like home depot and fill the mount up with it. i use this method on all of my motor mounts in all the vehicles i have owned. it works awsome and really stiffens things up.


order a bushing kit from like ebay. (they are the cheapest i think) you can get a complete kit with every bushing in the whole suspension. front and rear, upper and lower for around 140 bucks. also, you can try looking for just the trailing arm bushings somewhere and just order those. if you go this route, they will have to be pressed out to install the new ones.
