2004 X5 4.4i Automatic
I am noticing what I am describing as a thump occasionally from the rear of the car, anyone else had anything like this happen?
It's common as you are slowing down at junctions with an X5. There's plenty of posts on it but check the condition of your rear brake pads if it seems very strong?
Rear sub frame bushings are where I would look. They go bad over time. It can be done as a DIY if you are handy with tools. Think I posted some pics of mine somewhere.
