My car feels lower than most scrapes everytime i go over a ramp no matter how slowly i take it

One old timers trick I have seen work is to spray the hub area with rust penetrant, loosen the lug nuts a couple of turns, then drive slowly while steering back and forth abruptly. Of course, do this in a safe place not on the highway. If this works, you will hear and feel it 'pop' loose, then you can jack it up and get the wheel off.
Side note, do not lubricate the lug stud threads, as that will effect the torque value. Be sure to solvent clean the studs and nuts before reassembly. Also, a thread chaser is great to remove the rust from the studs.

Your ABS system is causing this problem have it tested by a dealer.

Factory stereo system?

try it and find out

I had a similar problem on my 2002 Escape, but it was also creaked when cold. It turned out to be an outer tie rod joint. It may also be a lower ball joint. My creaking would happen when turning the steering wheel even a quarter turn. I reached behind the tire and put my hand on the tie rod while my wife slowly turn the steering wheel back and forth. I could feel the very obvious vibration. Try the other side to see if you can feel the difference. Can you hear it when standing outside the car, and tell which side?

put car in 3rd gear and release clutch pedal slowly,if car stalls then its not the clutch...

Check you suspension/steering components. Something is damaged or worn out. Any minor (or major) accidents recently? Big pot hole, slid off the road, went over a curb, etc? Something may be damaged from one of these incidents. Are you the only one to drive the Murano? I ask, because I have seen people swear that they never had an minor mishaps, only to discover Jr. took the car out off-roading, and bent the heck out of the lower control arm when he hit a rock. No damage evident until it was checked for alignment, which was way out of whack. Drive the car up on ramps and look very closely for any scrapes, dents, bends, etc. It is most likely a suspension component that needs to be replaced. Let me know what you find. Good luck!

YOU COULD PUT AIR SHOCKS ON CAR.

Sounds like a bad window motor and regulator(s). You can try and lube the window tracks with some lithium grease or WD40 to help out for now.
