My ford escape makes whining noise and noise at the back passenger side

have the ac compressor inspected by an accredited ac specialist shop

i'd go with the wheel bearing , may not be any visable signs ie loose ness but get it changed

There is nothing that can make a whining noise in the back of the engine. Likely the noise you hear is coming from either the transmission converter or pump. Before anything else is done, check the fluid level. If the fluid on the dipstick smells burned, you definitely have an internal trans problem.

the reason you could do that was because it does not have positraction in the differential and it is designed that way for when you take turns so each axle can spin at a different speed. and the ginding noise with the brakes can be misinstalled hardware or a warped rotor.

fuel pump.get it changed before it fails.

bad hub bearing

If it's a growling noise,it's probably a wheel bearing.If it's a clicking noise,it's likely a cv joint,good luck,

You need to replace your wheel bearing. Ford Escape bearings usually need changed around 80,000+ miles from my experience.
