I replaced the engine mount today with the Powerflex poly bushing. It was easy to assemble after pressing out the old bushing.
I was really impressed with how
bad the old engine mount was. It was bolted to the frame with the wrong fasteners, missing a bolt on the engine, and completely worn out. I was fortunate to have all the correct parts on hand to reinstall it correctly.
Powering out of corners it felt wrong, but I am truly embarrassed that I drove on it as long as I did. Of course it feels a lot better now. I'll report back in a couple weeks how it compares to the standard mount.
