Hello I have a 99 gs400 and it started to squeak from the rear pass side. I have diagnosed it is coming from the RCA and where it meets the suspension. I took it to a alignment shop and they told me there was a bushing inside of it that was making the noise

My question is if I upgrade suspension in the near future will the squeak go away? Or will changing the bushing in the rear be the only way to relieve the noise. The alignment shop said that changing out the suspension to another one would make the noise go away but i'm entirely sure they know what they are even talking about

I already installed Daizen front bushings. I also tried to grease the rca to see if the noise would go away

The noise is very similar to this http://www.youtube.com/watch?v=ZFvhNYNmQ30

Does not sound like RCA problem...more like suspension (spring or shock) problem.

Did you buy used? the new suspension you have could have been compromised

Check out my thread man, I have had same squeaking noise as in video and the thing that has been causing it, turned out to be something not so obvious - xenon auto leveling "link"
