So,..if tightened while on the lift, that would make it easier to do wheelies on a race car then.?!

No, it will just rip the rubber loose when you let it down on the ground. Or, are you joking?

Just joking, but, if you tighten the nut at rest, what heppens when you raise the car on a lift? Does it "rip" the rubber then. Sounds like bs to me. Haeven help if the wheel falls in a hole or the front end bottoms out ( like in normal use) your rubbers rip.

Then it only goes half travel, but if tightened on the lift, it will go more than full travel when moving in it arc.

Wouldn't any travel twist that rubber?

Twisting is normal, that is the design, but when you exceed the twist limit it rips it loose from the metal it is anchored to.

I can't believe you are arguing about this. When nut is tightened at ride height, when fully compressed or fully ewxtended, the bushing is twisted halfway. The designers made the bushing for this use.
When you tighten the nuts with wheels dangling, when at level the busthing is already at its limit in one direction. Then when the wheel is pushed farther up, the bushing is past its workable range.

Also, it doesn't just rip or twist out immediately, it takes some time and number of cycles. But the service life of a rubber bushing misinstalled in this fashion will be compromised severely, like total failure in 1/10 the normal life.

Several years ago I got a ride in an A-body that had all poly bushings installed. It felt sharp. steering turn-in was immediate. I asked the owner his opinion of the bushings and he said he loved them for the reason I'd just noted, but in his opinion they transmitted more shock to lower ball joints, which caused the ball joints to wear more quickly.

Back in the day, a trick to stiffen factory rubber bushings was to drive small nails into the rubber. I remember this in a car magazine around 1975.

R.

Do you think that rubber bushing is glued-adhered to that steel pin?

What steel pin?

It's adhered to the inner sleeve, which is bolted to the pivot pin.

Just put it together like the book says, and stop worrying about the physics of it.

This..

Do you think it's attached to that pin?

I already explained how it attached.

Looks to me like he just answered the question,
"What steel pin?".

The bushing is pressed onto the machined end (right side in the pic above). They are a pain to remove.

FSM mentioned the shock bolts too, don't recall a mention of the upper control arm but it makes sense and after the alignment loosen/tighten I'd think that would be good

Hers's a comparison for ya.

DON'T mess with AC Delco non concentric

I took these photo's myself in my garage of parts I orderded.

Measure your Moog upper control bushings is all I wll say...... been there

...Already winter on Moparts?

The AC parts look better to me?'
The offset bushings are supposed to be offset?
Am I missing something

Cool, just trying to make people question instead of just taking for granted.

Don't think they offer offset on the lowers. The uppers can be had that way, but stock, no.
