MOOG balljoints beware
PN K500134 for uppers arrived from Amazon yesterday and all are silver/non-greaseable
I'm waiting for MOOG K6537 lowers to arrive today which are again advertised as greaseable. We will see what shows up.
A new alternative would be Proforged brand units which have been suggested and are greaseable.
Just thought I'd share what to expect.





Hopefully there will be even more alternatives in the future.
My solution was to buy a car with only 26k miles on it haha.






Or you can be savvy and just drill/tap for a zerk fitting. Not rocket science as long as you can keep shavings out of the inside.
The MOOG tech support said "ahh yes there was a revision and also due to the 'low volume' demand they switched to outsourcing and buying them instead of making them."
Which I promptly replied "well marketing needs to get on top of their stuff because all the info online is confusing/contradicting itself"....he didn't care.I have no idea if I even NEED balljoints. I'm doing a bushing install and figured I'd have parts on hand in case I needed them assuming 70K mi on originals and the fact I autocross the car it would be a good idea. If my originals are fine I'll send them back and get $400 back in my pocket which will buy a helmet I need for next season.

So I either lucked out getting the correct lowers or MOOG never made a change to outsource the lowers or both.
The lowers fit a wider range of years and vehicles than the uppers. So there's probably enough units of the lowers sold to meet Moog's goals. The uppers are C5, C6, and XLR only. Easier to buy a few hundred from someone else and slip em into yellow boxes. Also interesting is that Rockauto doesn't even show any applications for the Moog K500134

The real difference is that the Chinese worker gets paid $4-5/hr. to operate the machine, whereas in America, the worker wants $25/hr to do the same job. Also, in China, if the machine blows off a hydraulic hose, and spills a gallon of hydraulic fluid, before they can hit the "off button", they simply mop it up, spread some acetone around, and mop that up, too, while the hose is replaced. In America, the same situation occurs, and it's a "Federal case", with all sorts of "hazmat driven" procedures, and the machine is shut down for a week, while the "root cause" of the failure is investigated.
