My '95 mtx jerks back and forth when I shift. I feel the "herky jerky" movement underneath. It feels like the exhuast is moving back and forth. I just put in an entire new exhuast and an extra clamp on the cat-back for support. I replaced the tranny mount and rear mount. Is it the bushings on the suspension or the front mount? I can't think of anything else it could be. I need help here. I'll take any advice or suggestions to help cure this. Is it normal in the SHO? If it is the bushings, wil new subframe bushings help?
