Filling rear arm bushing with polyurethane.

[Caramanos2000]

Im considering filling in my OEM (working order) rear beam bushings with construction grade polyurethane to add some more strength. I have my tranny mount done this way with good results, so I figure id give this a try. Thoughts? Would be done in car and left to dry before use.

I'm curious to how this goes, i'm thinking of doing this as well down the road. What were the benefits of doing this to your Trans mount?

I can thrash the gears without having the engine wana fall out lol. Granted it came at SOME additional vibration when the idle bugs down, but barely noticeable.
