Some strut bushing info

That's actually a lot misinformation and as usual, and very incorrect. The do swivel. Many people use the slang "Swivel Joint" when referring to Heim Joints. Usually they are listed to have between 5 to around 20 degrees of swivel for most automotive application. They can "Swivel" on some Heim joints as much as 65 degrees. You would need to look up the manufacturing drawings and specs to know how much they "swivel", but they all do to some degree. It all depends on how much load you need them to carry.

The fact that they do "Swivel" is also the main reason they prematurely fail. If you were to have the axis of the ball close to the degree limit they were designed for (say 18 degrees in the attached picture), the rod end portion will dig into the ball. They work their best when installed close to 90 degrees so the loads are carried correctly through the race between the ball and rod end. I saw pictures on FAO where a guy installed Hotchkis upper control arms on his Duster and did just that.

Been using them for 30 years on suspension R&D test fixtures for GM. Installed correctly they can get cycled a million times. Installed incorrect I've seen them wasted in under 100 cycles.

Swivels are for fishing, not engineering.

20°’s of misalignment (the correct term, btw) is not swiveling. I've heard them called misalignment joints in professional settings, which is accurate.

The fact that you’ve been using inaccurate terminology for 30 years doesn’t make it correct, it's just slang not the proper term. Same as OMM being wrong about poly bushings for 30 years doesn’t make him right about them either. Doing something wrong for a long time doesn't ever make it right, it just means the involved party doesn't learn.

And “a lot of misinformation”? Sorry, but no. There’s a lot of information in that post, using the term “swivel” when you mean heim is the absolute least of it. The rest of the information is 100% factual, I’ve done everything else I said in that post and it works. Any high school kid can install LCA bushings if they've got access to a press.

And I know how a heim works. The heims on the strut rods on my cars have logged over a 100,000 miles of combined, year round, everyday street driving, I’m perfectly aware of what they’re capable of.

Any word on these?
Sure be a handy part number to have on site.
I've checked my sources with no luck.
Suppliers I dealt with 40 years ago aren't there anymore.
Thanks.

Moog is currently listing them as a 5-8 week delay, you have to accept that term to even place an order.



Amazon actually made me confirm my order again just now, they're listing as trying to ship by September 25th. Order has been pending since July 27th.
