The value and purpose of the preload is underappreciated. The inner sleeve of the DDB (and entire Metalcloak bushing) would be more robust if it had some preload to both seal the interface and also take up the slack from wear.
Does control arm bushing composition affect ride quality or NVH?

It is a significant reason why the JJ works as well as it does and the lack thereof is why others often don't.
Ok, I cant resist! so are you hypothesizing that I can preload a Rusty's joint and it will be just like a JJ?
where is the popcorn?
This is kind of the 3rd act in a year and a half long drama. Bonded rubber and preload are two significant characters in this story.
Somewhere between 2 & 3k miles.
The 2nd gen may be more long lasting. As I recall, Dave was told there was bad batch of the 1st Gen bushing.
Does Rusty's not require a press to assemble and install the snap ring? If so, then "just like" in that it would address one of the shortcomings. This assumes the existing Rusty's joint can withstand the addition of preload.
Do they unscrew themselves from the rotation like others similar to that sometimes do?
OP
I don't argue the preload thing. It works, and works well. Servicing them is the thing that bugs me. Some say that servicing them correctly requires disassembly, cleaning, and re-assembly. The zerks are mostly useless from what I've gathered. The argument I guess, if we are to provide one, is at what interval do we need to service them? What special tooling do we need to do this efficiently? And, how often do we need to do this?
I pulled my JJ apart after 75k, cleaned regreased them, didn’t see any wear, and put them back together. I’m not sure what the interval is.
Not saying I am doing it the right way or best way, but mine have at least 30k quiet miles on them with only an occasional shot of grease through the zerk a couple times a year. I know others with far more miles with similar care.
