Structural Failures Posted by Bill Homer [Email] (#3427) [Profile/Gallery] (more from Bill Homer) on Thu, 26 Oct 2017 18:20:48 In Reply to: Re: So you have to think, how/why do they fail?, Simon S, Thu, 26 Oct 2017 17:20:38 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The failures that I have experienced have all been structural, i.e. a bushing cap develops a longitudinal crack from the screw hole outward. Given enough time and inattention, a chunk will fall off and the bushing will become loose from the subframe; bumps start sounding like a bad balljoint. I've installed other versions of this part that were painted black, which didn't help much.
Perhaps the deterioration starts with oxidation of the aluminum, or maybe not. The horrible roads that we have in the Chicago area probably also play a role in this.
I know that some saabnetters have posted that they found stronger alternatives, i.e. stainless steel, but considering that the 9000 has been out of production for 19 years doesn't create a viable market for this type of part.
