Slight Vibration... but what is it?
 

I recently had to replace the struts on my 2000 ES(43k on it) due to the fact one was leaking. (Potholes are not your freind) They also changed strut mounts, stabilizer links and a half shaft. (Thank god for warranties.) Ever since I got it back though, it seems there is a slight... very slight... vibration in the accelerator pad and the steering wheel anywhere at or above 2000 RPM. I had it checked out and even replaced the motor mounts, but the vibes still there.

Any ideas on what could be the source? I've heard mention of CV Joints from someone, but I doubt its that.

Is it sensitive to engine speed, or vehicle speed?
If it's specifically 2000+rpm then it's nothing to do with CV joints.
If it's related to a specific vehicle speed then it can't be engine/trans related.
The best way to check is to drive at the speed where it occurs, note the RPM, and then bring the engine to the same RPM in a different gear. If the vibration is there again, it's engine/mounts/something at the trans or before. If the vibration goes away, it's axle/CV/wheel/tire related.

Thanks for the response. I think I forgot to mention that I have an automatic. So I can't really try it in another gear. But, I do notice that if I am below 2000 rpm, I don't feel it. Mainly that would be if I am driving in city traffic at or below 30mph. BUt, once I rev up on take off from a light or get up to 40mph AND the tach is above 2000, then I feel it. I really can't call it.
