You have 3 basic options as a replacement.

First is an aftermarket bushing. That would be the best for most street aplications but would also not last as long.

Second would be a delrin replacement for the bushing, but that would make way more road noise and bind the suspension.

Third would be a mono-ball style bushing replacement that uses a sepherical rod end to replace the bushing. That would allow freedom of movement and last the longest. It would also be the most expencive.

 

good find^^

 

What about a hard poly urethane bushing? Not one of the red soft urethane. And then welding some reinforcing aluminum to the area to strenthen the spindle?

 

Most of the red bushings you see are about 80% urethane. The problem with urethane is that the harder you make it, the easier it is to crack.

 

Alex, ... did you have any plans on making a replacement for the spindle/upright??
What about the spherical rod end you mentioned? I'm many people would jump on it since it seems more and more true coilover systems are coming out for the G/Z.

Do you think there is a strength problem with the upright when using the true coilover?

 

Subscribing. The Zeals started making some odd noises...hoping it is just the sways.

 

I have my Stance's on for about 2000 miles. The top bushing on the rear knuckle (Spindle) looks fine on my Z!

 

Here is a suggestion:

mine looked fine this weekend, i think ive got about 10,000-15,000 miles on it, cant remember exactly, im leaning towards 15,000.

 

Interesting, I might try this when I get mine.

 

Sorry for the insanely old thread revival, but did anything ever come from this? Do any companies offer a fix for this issue?

I am aware that the general consensus is that this isn’t as big of an issue as it is on some BMWs, but if there is even a chance that this is a failure point, I’d like to reinforce it. I will link a few more threads talking about this below:
