My car seems to sort a bounce. The car does not really bounce it just feels like it. It kind of feels like it is coming from the back of the car from looking at the brakes and rotors. They seem fine good thickness with pads and pretty smooth rotors. So does anyone have an idea what else it could be? The car has 185, 00 miles its rear wheel drive V8 4.1liter.

This question has some ambiguity to it but I think you may need to visit a brake/suspension specialist to determine what the problem is, diagnosis of these types of issues is always critical to ensure your safety

Yea all the places I have talked to around here won't touch a Infiniti. They tell me to take it to a dealership or a Nissan/Infiniti expert. I have called them places and they r high priced to just have them look at it.

Push up and down on the back of the car, if it bounces over one bounce before it stops you may need shock

Go to a suspension specialist, it sound as if you are describing a floating sensation, which may well be a soft shocker reaction, do this first.

It don't bounce more than once when I push on it. No it's kinda like bouncing when u get a flat tire. Kinda hard and several bounces till I stop all the way. I first thought like a bubble in a tier, but no, then a belt broke I put all new tiers on and still bounces.

Still sounds like a suspension problem, you better get a professional to inspect this first hand, we can't see whats going on, only offer advice on what you describe, some times a first hand inspection will spot the problem straight up.
