You would install them like you said probably. Or just use a press etc.

The spherical bearing presses into the outer housing thats pressed into the beam. The C clip holds it in place.

The shoulder of the smaller spacers go inside the bearing (half way) and then the long beam bolt goes through the whole thing, both small spacers and the bearing.

Its pretty simple really.

This setup is great as it has no flex, but allows for very free movement of the beam, both vertically and in twist.

Whats the service life on something like that? I mean I DD my car. I dont really want to have to drop my twist beam every year to service the bearings.

on a DD this would be a min yearly service, probably more frequent

I cant see exposed bearings liking salt and dirt and such that I put my car through. I guess thats something for people to consider.

Bearings are cheap and they probably only take an hour or so to swap. Still def not something youd want to put on a DD.

Yeah, they'd be a great idea if there were some way to have bearings that were sealed.
I know they make them because when I was doing the BMX thing years ago, my Redline bike had all the bearings replaced with sealed units which never gave me problems especially the crank bearings.
I couldn't tell you how many times I'd go through mod or wash the bike without worry with them getting ruined.
I still like Spence's idea of the impregnated brass washers that would fit on the existing poly bushings with some modifications to make it work.
This way the poly would go unmolested while the brass washers do their job plus they'd be easy to change out every year or so or as needed.
Anyway, I'm still crossing my fingers for something to come about with this problem that seems to be rearing it's ugly head.

There arent really any sealed spherical bearings. You can get them self lubricating and teflon lined, but to try and keep dirt out you need to use a sealing washer, which doesnt really seal that great. Its more of a dust shield.

Id post a link of the seals, but I cant find it right now. I have some I used on my tie rod ends.

Well my testers will be getting their sets next week, once they put them through their paces it will be time to finalize them and get a GP going

that's the problem. It's not the photographer's fault. Bigfoot is blurry. And that's extra
scary to me. There's a large, out-of-focus monster, roaming the countryside.

Jeffie, please have some of the testers have an autocross or two.
I think that's the best way to test these since all the load being placed on this area will be tremendous as seen with Spence.
Thanks man.
Keep us informed.

One of the testers is actually Spence

I wanted to cover all bases with testing these, a basically stock DD. A slightly modded dd/occasional track day attendee, and then Spence for the balls out testing.

I don't want to release something that isn't 110%, I wont let you guys or myself down by offering something I don't fully believe in.

That's the way it should be done and we thank you.
Knowing Spence for as long as I have, I'm sure he'll put them through the ringer.
Thanks Jeffie and we all await the response of the testing stage.
Btw, full documentation of the bushings with photos would be nice for us to visually see what's happening with the setup.

Sounds good. Hoping the delrin works out.

didn't have my phone or camera with me yesterday. (although they look exactly like the ones in the pics jeffie posted at the beginning of the thread.

i'll be sure to get some when I install.

when you install, are you removing the axle? it would seem that if you use a hydraulic jack and lower the axle once removing the two bolts that it could be lowered enough to remove the bushings...

anyone else agree/disagree?
Re: Rear trailing arm bushing FEELER.

god dave... its only been 6 years since i did that LOL (let me try and remember....)

iirc you CAN push the axle down far enough to where you could get the bushings out (definitely not stock unless you wanted a huge @!#$ headache)...

hahaha, i'll have to try it. thanks brad!

i took the stockers out and installed the lzm bushings by just unbolting the front bolts and letting the struts hold up the torsion beam.

plan on doing the same when I install these.

What's the Rockwell harness of the delrin?

Re: Rear trailing arm bushing FEELER.

These are made from Delrin and have a Rockwell harness of 89-94.

ok... here we go...

lzm carnage





what this carnage did to my 245


jeffie's prototypes




initial findings are that jeffie's bushings are better fit than the LZM's. After installing them, i've found that the side to side play from the LZM bushings is gone. i can't wait to get out this weekend and put the car through it's paces to see how they work.
