I have used Moog LCA bushings on several replacements and had no problems. This last batch was constructed differently than the previous ones. The older ones had the rubber apparently tightly inserted into the space between the pin sleeve and the bushing outer shell. Thus, when I removed the pin from the old bushing, the sleeve came out with the pin. Then, I could get a screwdriver between the shell and the rubber to pry it out. However, the newer ones seem to be bonded with some kind of super-**** so that the pin sleeve/rubber/outer shell are "living as one":realcrazy:. When I pushed the pin out, it came out of the sleeve by itself and the sleeve stayed behind with the rubber. At first, I thought that was a good thing...don't have to worry about cutting the sleeve off of the pin. But then I started trying to get the sleeve and rubber out of the shell so I could weld on attachments to push the shell out of the CA. DAAAAYUMMM!!!! I cut, punched, pushed, drilled...literally took hours to shred the rubber and eventually get enough of the pieces out to be able to weld a washer to the top of the shell.

Oh, and by the way, the way the rubber is bonded to the new bushing and shell, it laps over the top of the shell where it used to be bare metal. That caused the pipe that I use for a mandrel to install the bushing into the CA to "squirm" under pressure...very difficult to keep the mandrel straight up/down and get a good centered press.

IMHO, they fixed something that didn't need fixin'
 
Ya, if you do lots of suspension rebuilding as i do, you have noticed the LCA bushings are now manufactured differently than the older ones.
I have run into the same problems with the new style that you are writing about.
But it's not just Moog, with the name on the box, it's now everyone that you buy from, as the manufacturer of all the bushings is a company named HARRIS that sells them to anyone that puts them in their own box.
I have been trying different methods, techniques, in getting the bushings into the LCA, then the shaft, or putting the shaft into the bushing, then everything into the LCA.
Haven't figured out a good new method though, yet.

But i bought a stock of bushings from a company named Proforged, that are made well, under the old style method, that i like, and install well.
From now on i will buy that brand.
Might want to check them out, the next time you are rebuilding a pair of LCA's.
My two cents worth on the subject.
The LCA's in my pictures are the old style, manufactured, bushings, before i went with Proforged.

I knew Moog parts were different. Recently got Sway bar links for my Magnum and they were cast completely different than the set I put on a few years ago (Moog, but also junk, lol) Did not know they boxed another mfgs parts.

I have 25 year old Moog K791’s and they say Harris too.
 
Oh, and by the way, the way the rubber is bonded to the new bushing and shell, it laps over the top of the shell where it used to be bare metal. That caused the pipe that I use for a mandrel to install the bushing into the CA to "squirm" under pressure...very difficult to keep the mandrel straight up/down and get a good centered press.

One method that i tried, and seemed to work well for me is, i have a bench grinder with a 6 inch wire wheel brush on one end of it.
I wire wheeled away that excess lip of rubber on the bushing to keep the pressing in "driver" from moving around the top lip of the bushing.
Seemed to work well for me, so I'd do it again, in the future, if i had to use the new style, manufactured, bushings.
 
Went through my picture files of recently sold LCA's that i rebuilt.
Here's two pictures of the differences in the molded rubber that were talking about.
Hope you can see the difference.
Maybe blow up the image on your computer.

The "New" bushing is the first pictured.
The "Old" bushing is the second picture.
