2004 Crossfire 6 speed with 96k miles. Just returned from mechanic to see if he can diagnose a really bumpy ride by needing new shocks. Car rides very bumpy, started a month ago. I feel every bump even minor/small road issues. I've had the car for 6 years and this problem just started. Tires are 1 year old in great shape. He ran a diagnostic - no issues. Inspected shocks - in great shape, no leaks, cracks, etc. ANY Suggestions and what the problem might be?
