you probly have a belt slipping, a can of belt dressing should stop the sound
lack of oil
Fuel is not good!
Yes.Equally likely is if the belt is much more than 3-4 years, the material is glazing over or hardening, which is another common cause of squealing.
It could be a bearing in an idler pulley.
A worn or loose out of adjustment drive belt could be the cause.
it could be that your brakes are dirty or that you need new pads
could be a bad plug
You have no wheels. - Geoff
LOW AIR PRESSURE IN YOUR TIRES loose accessory belts such as alternator can squeal
It could be your motor mounts (usually always slightly vibrating the car, especially when accelerating) or most likely not aligned/damaged driveshaft on rear wheel drive vehicles.
Look to the alt. belt. It may squeal under load.
if its squeaking it could be to do with the suspension joints or the the suspension bushes, you will hear this mostly when accelerating, braking or going round corners. if its squealing all the time it could be your cam belt or the brake pad squealers, they squeal when they are too worn out and need replacing.
