View Full Version : Suspension question

Did a quick search and just seen lists of angles from alignments...so I figured I'd ask any of you guys about it before I went on to the rest of the questions.

I recently got a printout of my alignment and my front passenger wheel is at about a -3.5 degree camber (really noticeable).

After seeing this, the mechanic and I went through where it could be leaning in this far and we determined it to be coming from the 'SAI' angle. I guess this is the angle from the shock and the body from the vertical?...that was my understanding of it anyways.

Any of you guys know what this is? I have couple more questions, but there no point in asking them if no one knows what a SAI angle is...

Any help appreciated!

http://www.familycar.com/classroom/Images/Align_Included.gifSAI = Steering Axis Inclination. Included angle is the angle formed between the SAI and the camber. Included angle is not directly measurable. To determine the included angle, you add the SAI to the camber. If the camber is negative, then the included angle will be less than the SAI, if the camber is positive, it will be greater. The included angle must be the same from side to side even if the camber is different. If it is not the same, then something is bent, most likely the steering knuckle.

I <3 you. Thanks for the info man.

Now...based on that...I have a terrible (-)camber and it needs to be fixed sooner than later.

I know there is a myriad of possibilities as to what's causing it...so I'm not going to be able to determine a solution until I find out the problem. From what me and my mechanic discovered is that the top of the shock isn't looking that healthy...you can see how disfigured it is at the mount in the engine bay.

So, based on this, I think I'm going to check out the shock to see if the rod is bent at the top then move up from there. My mechanic is suggesting a camber kit, but the farkin things cost $400...which would be a complete waste of money if the new suspension setup (on the 'want' list) corrected my problem.

I guess I'm looking for anything else I should be keeping an eye out for because I haven't had too much experience with suspensions...any thoughts?
