Namely, I need one. My Spirit has developed a thud in the front end, over SOME bumps. Different from the pop/bang that my strut mounts were causing, this sounds like someone hitting something with a rubber mallet, which makes me think that there's some bushing or rubber mount getting whacked. There's no pulling at all, and the car has stayed in very good alignment. Struts are Monroe and very fresh, less than 5k, and the car handles surprisingly well, so I assume everything is kosher there. Letting off the throttle at highway speed (cruising to closed) is best described as violent, and it doesn't feel at all like the '91 I was using while my '95 was laid up. There's no noise that I can hear though. The sway bar bushings look pretty mangy, but I thought sway bars rattled... anyway, I need a test for the engine mounts, any good ones?
