Just noticed it today for the first time. The car pulls along fine, and seems to brake without a problem. However when the car is slowing down, but a LOT so when coasting to a stop, there's a kind of "dumf dumf" noise that repeats in time with the turning of the wheels. It sounds like the noise you'd get if you had a flat tyre, but I don't.
What's more, I can feel it through the seat and steering. The steering wheels actually jolts from left to right.
I thought it might be the tracking, but don't see why it would just suddenly decide to go wrong, plus it accelerates fine without making the noise. It's only when slowing.
Any ideas?
