Re: Solved: Floppy New Lower Ball Joint Normal?

I'm starting to wonder if my machine shop disassembled the BJs to safely press them in, then reassembled carelessly. I didn't scrutinize the new BJs before assembly but I think I would have noticed this as a potential problem even from casual inspection.

A full exploded view of my adjustable ball joints before I installed them today. I like that the ball is made in 2 halves. When the load is pulling upward on the ball, it may turn inside the small shaft diameter rather than turning the larger diameter ball. Lower friction, potentially saves some wear & tear. Interesting adjusting the BJs. From "bottomed out" and the joint stiff, just 5 degrees of loosening the adjustable lower ball socket loosens up the shaft. Very easy to tilt & turn compared to the new upper BJ, which is very stiff.

Many many years ago....back in the mid to late '70's Moog offered an "Adjustable" ball joint.
While the idea was good in theory, they were not without their issues.
A friend had them in his Late convertible and had one fail shortly after installation.
It would not surprise me if there were other companies that offered them as well, but I imagine there is a reason they are not offered these days. :my02:

Oh come on, JC Whitney wouldn't still be in business if they sold me bad parts... :doh:

Wait, they're out of business...? (they survive in name only: https://www.carparts.com/jcwhitney/)

I'm not alone in loving their old B/W catalogs, like the old Johnson-Smith novelty catalogs. They were like Harbor Freight for car parts. Remember they didn't sell spark plugs, but FIRE INJECTORS!!! And other ridiculous stuff.

Regular ball joints are cheaper than adjustable so the only adjustable ones you can find are expensive racing parts and of course none are available for Corvairs.
