Rear end differential and axle
I'm having problems with our 2007 AWD Equinox which has 131,000 miles on it. It's in really good shape. We've replaced both front hubs twice. Last week my wife said she can feel a vibration when she accelerates. Had the tires rotated and spun balanced, still a vibration especially when going from a stop to 30 MPH. No vibration in the steering wheel or the gear shift lever. The seats vibrate, that's how bad it is. I'm afraid to take it to my dealer because it will cost me a diagnostic fee. I rocked the car back and forth in park and think the noise is from the differential or the axle? My local mechanic that I use for brakes etc. said they could look at it but it will probably be expensive! Does anyone have an idea?
Es esta una buena pregunta?
