seemingly endless issues with my 914 Group: Members Posts: 218 Joined: 13-February 07 From: Chicagoland Member No.: 7,532 Region Association: None |
Installed the poly bronze front bushings last spring. They were binding. To alleviate some of the binding I bought, from McMaster Carr, spherical washers for the frontside mounts. This helped quite a lot, but there was still a bit of binding. I figured I also needed spherical washers on the backside mounts as well to get these things to rotate without binding. My plan was to replicate the $200 Elephant backside mounts by machining enough material off the top and bottom sides of the backside mounts to accommodate spherical washers. I began this project today.
When I started to take the control arms off the car, every one the base (concave) sides of the washers fell off in pieces. I couldn't believe it. When I assembled this stuff I only gave them a good snug down with a socket wrench, no over tightening. I do not want to continue this project and modify the backside mounts if the conical washers cannot hold up. These are the washers I bought for the front mounts, same manufacturer for the backs, just a larger size. I bought case hardened steel rather than stainless due to the 12 sets x $15 per set price difference. Has anyone had a similar experience? Any advise to help me get this resolved will be greatly appreciated. |

The A arm.....er....bearing surfaces are not co-axial to each other or even round.
Obviously they were not designed to meet the tolerances which are trying to be applied here. Some of these issues were attacked with the Sine(sp?)/Mueller/ Free Motion needle bearings.....the hardened sleeves, for instance. The needle bearings allow more latitude as the needle bearing resist binding better....*I think*. (IMG:style_emoticons/default/biggrin.gif) Mine moved around freely ....but maybe my A arms were more co-axial. Another set of arms may be a possibility. |
