Hey guys. My 08' CX9 has 160k and I've changed leaky rear dif fluid but I haven't touched the trans or transfer case up front.

Lately at low speeds coasting, when you give it has there's a perceivable bump and what seems like slop in the front of the car.

I'm aware of the transfer case issues with this car but the symptoms seem to be whirling and grinding. Most of the problems 'bumping' I could find here tend to be in the back of the car.

Where should I start looking?

Thanks.
