2000 Mitsubishi Eclipse Help! Frustrated!

Engine mounts on our cars do wear out, so that could be a possibility. I would wait on doing that though to see if it gets worse.

I would jack it up, spin the wheel and check bearings and then inspect/rotate your tires. An unbalanced wheel or a bad tire would also cause vibration. One flat tire on our cars can ruin the tire and cause a bulge that if its on the niner side of the car you won't be able to see -- that sucks.

CV joints do the clicking when you go around a turn. I can't rememnber if its a hard left or right turn or both. But that is the traditional sign. So if you don't hear that -- then I wouldn't get the CV worked on. And they'll click and be in going bad condition for thousands of miles. So there is no urgent need to jump o that.

I would definitely look at your wheels, tires, sounds like you have a bad tire or a wheel out of balance. Maybe lost a wheel weight.

My 2000 gt at 130,000 miles is doing the exact same thing but the vibration is mostly coming from passenger side, front end! All of my wheels & tires were looked at, balanced and aligned & that is not the problem. I just also replaced the passenger side with new wheel bearing, axel, the bearing and seals where the axel and intermediate shaft connect replaced, lower ball joint and etc. A few hundred dollars later the car is no better :( I was told by numerous mechanics they had no idea and one told me it was the tranny, I spoke with a tranny expert in my area & they said they had never, ever heard of such a thing. Anymore suggestions?
