40 Rear Shackles in Polyurethane

[TJ]

I just tacked them first then ran a bead. They will never come loose. After allot of research, I decided to run nylon bushings. Another important step is to order Formula 5 grease from Energy Suspension. Energy claims that if you use their grease, squeaking is no longer an issue. I really don't like the stock rubber ones because as the spring rotates, the rubber is torn from the inner sleeve. Nylons will hold up better and no squeeking with Energy's special thick, waterproof grease. Watch their video, very convincing.

I've used the grease from Energy Suspension and it works great. Used it on the bushings in my '40. You don't need to use a lot of it. It goes a long way.

Their grease is so sticky, they recommend you don't get it on your hands and use latex gloves to install the stuff.
