First thing is the wobble, it only happens when accelerating, and braking but if I just let my foot off the accelerator, there is no wobble. It starts at about 60, gets really bad at about 80mph, and then better at about 100mph, but still a bit of a vibration. Feels like the whole car is vibrating but it feels quite bad through the steering wheel.
The second thing is that the back end sways from side to side on its own, I only noticed it when I was on the motorway and had to swerve when someone cut me up. The front end straightens up, and the back end feels like it is swaying from side to side, kind of makes it feel like the back end isn't connected to the car.
Any help would be much appreciated.
I am suspecting rear beam mounts, the vibration feels like it's coming from the back, and the swaying as well. Just need some confirmation, or if there is something I am missing.
