Having the experience of rebuilding Matt's barn find, we noticed that there was rust around the edges of the tubes that went through the control arms. After cleaning these up we noticed that these were constructed from hollow tubes that had a plate with a bolt end welded on. The welds had not been cleaned up well and rust had pitted the them and allowed for water penetration actually allowing the inside of the tube to rust.
We made replacement simple. Machining the new tubes from stainless steel they will never be able to rust and fail. Once we had the center shafts ready we made the bushings from rubber just like factory. These proved difficult to install, so we switched this up to poly-graphite and they we much easier to install. So our "kit" comprises 2 - solid stainless steel pivot shafts, and 4 poly-graphite bushings. I have 2 other GBs I'm about to post - The front strut top rubber replacement The A arm bushings - with or without special tools to install Attached thumbnail(s) |

I'm still trying to decide on these. I want to stay as close to the factory ride and feel as possible since I always thought that was about as perfect as it gets for a street car. When you say the rubber bushings were difficult to install, does that mean impossible, or just that you would need a press? And are rubber bushings off the table based on your experience with them? I think I'm in, but I'm totally clueless about how much harder bushings translate to ride comfort. Hopefully, it is negligible. (IMG:style_emoticons/default/smile.gif)

(IMG:style_emoticons/default/smile.gif) I bought and installed a set of the rubber bushings by Elephant Racing. Took me 12 hours and a lot of swearing with the tools they supply. The problem is with getting the shaft pressed into the bushing. The shaft wants to bunch up the bushing and push it out of place. Seems to be a science to install them using the right amount of heat and lubricant to get the shaft to slide into the bushing. The poly bushing act more like a bearing with the bushing rotating around the shaft. The rubber bushing act more like a spring as the shaft is fixed in position to the car. The dampening effect or the rubber is gone when using the poly bushing. I am not saying this is bad, just different. Poly is going to act more like the true bearing similar to the poly bronze ones. |

Figured for the price and ease of installation, these are worth a go. Based on your replies, I think I made the right decision. (IMG:style_emoticons/default/biggrin.gif) |
