Does control arm bushing composition affect ride quality or NVH?

After working on helicopters in the army for 8 years, all joints that are not pure rubber can do that fairly quickly when they decide to go...that is why I am looking at the synergy bushings. They are the closest to a rubber impregnated, multi layer lord mount that I have found in the auto industry. Tim
You are a bit confused as to what you are seeing. That is the aftermath of him taking a ball joint press to the ball and shoving it through the washers, hardened ones at that, which retain the urethane races and the ball. That pic should only be used to define ignorance of a system and how it is supposed to be disassembled.
The reason that the joint was loose is very likely due the ignorance of the fabricator who welded it in place without removing the urethane races. We see it all the time.
You will not regret the use of any JJ in a suspension application regardless of anything others may try to convince you of. I have been running them personally since about 2000 and have installed hundreds of them. Since I am on the hook for any issues that generally show up with components I use and install, I tend to be very careful in what I select. I have never regretted the use of JJ's in any of my builds. Nor have we regretted the use of them in any of the race cars they have been used in.
Lube them with the Redline Red Moly and you can almost rotate the ball with your fingers.
And they do definitely lay it on too. Our product is so good it only works with our product. My favorite is this
They actually said why on here. We did it because KEVLAR!!!!! We don't know if it helps, we don't think it hurts, and it doesn't cost you any more, so buy our stuff. Said by Matsun if you can find it. It would be helpful if folks understand that the Kevlar used in tires is in the form of the belts and the Kevlar in bushings is ground up fiber.
If the Kevlar fuzz is there to add reenforcement to the bushing material, was there a problem that needed to be addressed?

Probably increases toughness, that is why I have used Kevlar in composite matrix before.
They are good so far. Not her Jeep but the test mule. I don't wheel it enough to find out that aspect but the rest is excellent.

You can use a synergy JK bushing if you want to go with a larger bolt, if not the JJ is second choice for me.
I am going with JJs as you only install the main bushing bodies once vs pushing them in each time you need to service them. To me that makes more sense than risking messing up the housing or passenger side bracket. Synergy used DDBs with JJs in some of their arms when they were first introduced so centering is really not an issue or they would not have done it.

After spending hundreds getting rid of my RE super flex control arms and going 100% rubber joints, All rubber joints on my new track bars, rubber in my shocks, my ride is smooth and has less felt vibrations, to me. I am more of a fan of rubber than poly.....
