Soliciting interest level in Spherical Bushings

I doubt you'll get much interested from Aus, maybe only a couple of the more extreme guys on here... maybe.

Most modified 4wds here are driven very long distances on rough high-speed roads (relative to most other parts of the world.). We put up with extra noise from aggressive/heavy tyres, bars/luggage and sometimes heavier suspension as they're fairly critical items.

But I doubt many owners would be happy with increased suspension noise for say 8 hours/day over a week or month-long trip, just to have a bit better articulation. Particularly with QDII.

Whoops I forgot to quote this.
The poly bushings of the hardness popular in the US (just for example.) are generally avoided here due to the noise, especially in 4wds.
Often used once as cheaper and usually easier replacements... and replaced with rubber some time afterwards .
So I'd-say it would still put people off the spherical bushings.

Softer poly can be found of-course, but they tend to get neglected and torn with the amount of movement in the suspension links. Still popular for steering and drivetrain mounts though.

I would be far more interested in spherical bushings for the thrust arms in my E34 chassis BMW 540i.

I agree with James on the other fronts. Plus rubber is far less destructive on other suspension components than poly.

Why not? We are Jeep fanatics but can build these bushings for any car. What I need are specs or an OEM bushing to take measurements off.

You can get what you need from a company (or a guy) in Germany called Wokke. People who used their stuff swear by it. They are sealed spherical bearings that are proven to work well in BMWs. Do a Google search on Wokke bushings and it will show you options for your e34. Good luck.

Thanks, cheers

We use softer poly with qualities similar to rubber for that reason. We use that poly for our track bar, sway bar links, suspension bushings, ..etc. we try not to compromise the day to day comfort while giving the long service life benefits of poly.
