There is no proper way of installing junk. LCA bushings with poly are free. Up and down front and back they move very free.LOL.
Also the poly strut bushings don't have shear sleeves molded into them. Foot braking a car shears them off where they fit in the K member due to their crumbling effect. Yes I know they have inner sleeves that have to be used with 73 and up coarse thread rods. The bottom line is you can't make perfume out of ****. Well you can but it still smells bad in the end. We will never agree on this only because in reality they are a product that don't function as good for a long time as OEM.
If I remember correctly the last time I mentioned the shear sleeves. You posted a picture of the sleeve that slides over the strut rod that the bushing slides over . So you my friend do not have a clue what the hell you are talking about. I have been building suspensions for a very long time and tried all the new products.
I have see the downside of them all. Poly bushings are for the do it yourselfers that don't have the equipment to do it correctly. You know , push out the rubber . Leave the sleeves in and slide in the poly with a lot of lube. Don't forget to install those pins with grease fittings so you can keep on lubing them. So they move freely Up and down and front and back. End of story . Oh yeah whats with the name calling I thought that wasn't allowed. Ah but your special. You must know the moderators. "Stump" could mean a lot of things , You could have called me a tree. LOL
This is ongoing. I will never agree with him. My experience with poly was when I went up against the front wheels footbraking the Duster. The poly bushings crumbled and we saw pieces come out from under the car . I eliminated travel and increased my 60 ft . But it was only a mid 10 sec car.
OMM- Has never installed a poly bushing that hasn't failed in a short period of time, according to him. That includes multiple brands of bushings, different applications, and even different vehicles if you read his responses.
72blu- Has never installed a poly bushing that has failed, in some cases that includes over a decade of use and tens of thousands of miles. That also includes multiple brands of bushings, different bushing applications, and vehicles.
If you eliminate the brand of the poly bushing, the application, the use, and even the vehicle they're installed in, you've eliminated every commonality between all of those poly bushings except for one. The guy that installed them. That's the only thing in common between all of the failed poly bushings that OMM has installed. All of them failed, and all of them were installed by the same guy. Literally nothing else is the same, and that's according to him.
I've never had a poly bushing fail. I'm not saying in the history of poly bushings that a bad one has never been made, but none of the ones I've installed has ever failed. Heck so far none of them have even worn out, although I'm sure they will eventually. I've used them on classic cars, I've used them on modern cars, I've used them on 4wd trucks. I've used poly LCA bushings, poly sway bar bushings, poly radius arm bushings, poly cab and body mounts, etc. Some of those bushings have been on my vehicles for over a decade.
Yes, there are applications where I wouldn't use a poly bushing, like on the strut rods of these cars for the reasons I explained earlier. If you understand how the bushing is supposed to function, and you understand how the material works in that application, you can intelligently decide what materials will improve performance in that application and which ones won't. If you don't understand that, you're just slapping parts together and hoping things work.
Clearly, I'm not the only person here that has successfully installed a poly bushing. And I know that they won't last forever and they're not right for every application, but the same is true of rubber bushings.
