Why are all the measurements on the MC joint imperial, except the hole being metric randomly?
New control arms (Savvy versus Metalcloak)

You'd be the first I've heard of to try that.
Buy one as a tester and let us know if they fit. That would be pretty cool.
i did replace most of my MC joints with JJ's. still have a few but they'll be swapped out when i stop spending on everything else (lotta projects goin).
if you have DA aluminum links there is no need for new 1's as long as you can match the thread size and pitch.
i just looked at rock jock the other day and joints are 60$ ea.
last time i looked at an MC, they were both within a few dollars for whole joints or replacement centers.
the JJ does require a tool to be bought or made if you need to take them apart for service.
innards? if your asking if the JJ bushing will fit an MC barrel, that'd i'd not bank on. the barrels just a piece of tube but it's what they do to it inside that might differ, the machining for retainers may not be similar. that i did not do or attempt.
but if you have double tapped alumnim arms you can buy whole joints...................so now i'm a tad cornfused. i thought you said DA links.
I’m gonna assume here and say that hole is made to factory specs to match existing
Yeah, I think you’re right after reading a bit today. Currie’s instructions also say that the bolts they include are 7/16” and the hole is metric and will need to be drilled out.I’m gonna assume here and say that hole is made to factory specs to match existing
It would have to be drilled out if it was SAE since 10mm is just slightly larger than 3/8". Currie isn't having you drill because it is metric, they are having you drill because you need the larger bolt.
The reason you don't drill the lowers is 9/16 is only a few thou larger than the stock 14mm bolt and is generally within the clearance hole size you would use for the smaller 14mm bolt.
I think people get intimidated about drilling out the top holes. Once they do one and realize it takes about 6 seconds per corner the hesitation goes away real fast…

Until you’re drilling the uppers on the axle side… fuck that. I never want to do it again.
I thought everyone knew to use the 4 OEM bolts there and make two bolts with two nuts from what you removed?

I thought about it, looked at the nasty hardware I removed, then decided I should drill it out and use the new hardware in the pack. Next time I'd go to the store and buy something instead of drilling. Lessons learned.
We almost never drill those out. Way too hard and sometimes you get a bushing with a hardened bolt sleeve that just eats up drill bits.

Hear tale that you should disassemble new JJs and grease before installation. Any truth to that?
I drilled mine out and it took me almost an hour to complete the two. The cycle was drill, cool, sharpen bit, and repeat. It worked, wasn't fun, and I don't think I'd do that again!
I heard the same thing so I disassembled one when my new CAs arrived. It was all nice & greasy so I just installed the rest of them.
BTW what's the recommended interval for disassembly & servicing? Once a year? Do you all just wait until they get a little noisy?
If one insists on doing it the hard way and risking running into a hardened bolt sleeve, the best way to do it is with a 7/16" chucking reamer. I've done several with the same one and it is still sharp. Only a solution, not a recommendation.I drilled mine out and it took me almost an hour to complete the two.

We wait until they make noise. For many sets installed years ago, we are still waiting.
I would at least check them. I had to grease most of mine within 8 months of putting them on. Granted I live in a more clay-soil state which apparently sucks them dry faster.
However when I got Currie track bars and the joint housings for the front axle I went ahead and opened the joints. All of them were pretty dry, so I’d say it may save you a bit of annoyance to grease them before install, even if it’s not necessary.
