Suspension refresh/upgrade Control Arms

No affiliation here but saw these on sale. Somebody more knowledgeable here will know for sure if the H1 bushings will fit the HMMWV's? I'm going to order a set for the future. Most of our HMMWV's don't have a lot of miles but age wise the rubber is deteriorationg. I've never tried Energy supsension brand, just Powerflex in my sports cars but I know they've been around for years.

They work good for awhile but after a few trips off roading they will start to make noise, urethane sqeeks!! they do hold up well

I get what you are saying about Poly bushings. I know of some that have grease fittings that allow you to lubricate them to keep the noise away and wear low. Supposedly Energy Suspension's Black Poly have some Graphite embedded which is supposed to increase life and decrease noise, we'll see. They do make some Red Poly which don't have the Graphite.

I used the black ones on a 67 Jeep. So far so good. I wouldn’t know if it squeaks due to all of the other rattling and squeezing!

Probably the same on the HMMWV for the most part. Sitting right next to that engine cover, not sure I'm going to hear any suspension squeeking either.

Poly bushings are good for some applications but I’d steer clear of them on the Humvee. They won’t last nearly as long and the problem with poly is when they fail its catastrophic. With rubber, they will last longer and only slightly deform as they begin to fail making them a preferred option.

I manufacture and sell a tool that makes replacing the bushings much easier. I’ll be doing a run of them very soon for more inventory.
