Hi guys, I’ve got a 2011 Dodge Challenger SE Rallye Redline with 73xxx miles. Tonight while driving around, I suddenly started feeling the rear end begin swaying side to side lightly at 25-30mph. At first I thought I’d accidentally pressed the traction control button at some point, but no. The road I was on was completely smooth and there was no gravel/oil/etc to warrant this sudden behavior.
As I was trying to find a safe place to pull over, the swaying began getting worse and worse. It felt like I was driving on an ice rink. When I did regain control of the car, it seemed to drive “crooked”. It felt like the car suddenly threw itself out of alignment very badly at that very moment. I had to fight the steering wheel to stay in my lane.
As I accelerate from a dead stop, the wheels in the back seem to drag a bit, then the weight in the back feels like it shifts slightly to the right. I checked all 4 wheels to see if one had gone flat or was low on pressure, they were all fine.
When coming to a stop, there’s a light vibration (unlike what you’d normally feel from bad rotors) it felt like a droning grind when you lay on the brakes and roll at 2-3 mph.
I had my rear brake pads and rotors replaced about a month ago. It was driving great until about an hour ago, and kept getting progressively worse on my crawl home.
I did some research and came across Rear Cradle Bushing Failure, but it seemed to occur in the 2010 and earlier Challenger models from what I’ve read so far. It’s probably happened in newer models, but I’m not sure. But with the bushing failure, there seems to be no warning like I have now, and no one described a fishtailing/swaying effect from it.
Could the shop have installed the rotors wrong somehow, or put the tires back on incorrectly? I’m going to have it towed to a dealership this weekend, but I’d just like some input from others in the meantime, thanks in advance.
