I got all 4 struts replaced on my 2005 LS430 and when I left the shop I had some kind of suspension noise. Hard to explain but it's like a subtle knocking or clanking noise! I hear it even when riding on a smooth flat surface. Don't hear it so much at high speeds and it doesn't increase at all on bumpy roads or potholes. I had the shop take a look and they think it's the sway bar links. Keep in mind I had ZERO noise prior to the struts being replaced. I did not replace the strut mounts but the shop assures me that's not it. Somebody please help!!
