About 2 months ago the caddy dealer said I needed to replace both wheel hubs on the front. The passenger side has been riding rough for about 3 years, ever since I hit one of the "manholes" that sit about 3-5" high when they're about to repave the road. I've had at least 3 alignments since this has happened. I recently replaced the front passenger side wheel hub. My problem is that I feel every bump on the front passenger side, seems as if the wheel is just hopping around. I've recently had the tires road forced balance & they checked out to be fine. If I stand in front of the car & press down on the front driver side it bounces just once, pressing down on the passenger side it bounces up 2-3 times. Every shop I take it to says the struts are fine & I should just replace my driver side wheel hub.
