If you have Air suspension this can happen. The noise you hear like from an engine is actually the airpump trying to keep up.

The hissing is air escaping and the bouncing is an indication that the suspension is not fully inflated.

There are individual bleed valves so the system can be leveled by itself. The valve on one suspension unit may be leaking. Sometimes soapy water sprayed while the part is working and again while shut off will show a leak.

Some Makes have a diagnostic plug which a scanner can read to find the problem. Often a car is jacked or lifted on a rack and someone did not turn off the Air system and knocked it out of alignment.

I hope my solution is helpful and enables you to diagnose the problem now.

sounds like it may have an exhaust leak, rusted pipe or gasket that has rotted out, lift car off ground and look at the exhaust system and the power steering may be low on fluid. Hope this answered you questions.

Sounds like you have something rubbing, since you are not loosing air and there is nothing else to hiss,, an exhaust leak would have a different sound. I have seen debris get wedged in the brakes and make a noise when you are underway. The sound would vary, depending on what sort of debris it is. I would remove the wheel and look for the culprit. Your brakes may need to be religned as well. Sometimes the audible brake wear sensor will make a noise like that. Good Luck! I hope this is very helpful!

is there an odor??
sounds like maybe a leaky a/c evaporator core!!

If the back brakes are drum brakes then it`s just water in the rear drum.
The hissing noise would be the hot brake drums boiling the water.

At that mileage it could be, and most likely is given your description of the noise. I assume it reduces in volume as you slow down. If you can find a quite piece of road drive up to where the noise is apparent and lightly swerve from left to right. (Don't roll the car!! ) If the noise reduces as you swerve left then its the left bearing. If its when you swerve right that the noise reduces its the right bearing. If its both the only way is to jack the rear up and spin the wheels as fast as you can and listen. If there's a hint of a rumble from it, its that bearing or both. It should be completely quite apart from the slight hiss as the shoes rub on the drum.
35K may not seem much but if you don't know the history of the car it could have hit a bad pot hole or even had a knock on a kerb.
I have replaced bearing with a lot less miles than yours.

yes when you make the absoulute full turn your hearing like a hissing noise this is normal if this is what your hearing then problem solved but if has a different sound than that like a rubbing sound then check the fender wells to see is there is any rub marks this can be corrected by putting in a turn stopper

yes that is the expansion valve! there is a hissing sound from the restriction in it for a pressure drop thats what makes the a/c cold the hissing is normal
