Sounds like there are two possibilities.

A slipping belt that drives the alternator or the air conditioning can cause a horrible squeal. I am not sure if the Corrolla has a single belt or two belts. They drive the Water pump, the air conditioning and the Alternator off of the main crank shaft pulley. If so these belts can all be adjusted.

If there are two belts - one will drive the AC and the other will drive the Alternator. If its the Alternator belt that is slipping it should get worse if you tirn on the head lights and the rear window defroster as these draw power from the alternator and make the alternators job harder. If its the AC belt that is slipping then when you turn the AC on it should get worse. If you only have one belt then turning anything on should make the noise worse.

Typically to adjust the belt there is an adjuster nut on the Alternator assembly. You typically have to loosen the mounting bolts on the alternator slightly prior to stretching the belt and putting more tension on it and then re-tightening the bolts once the belt is tighter. Depending upon when the belts were last changed it may be time to replace them.

Getting to the bolts on the engine to do this work can be tricky and will be easier if you are familiar with the location of the components and the location of their mounting bolts. Really the best way to work this out and to get some idea is to go to a local car parts place like Autozone and buy a manual for the car (about $20) and this will be a huge help for this minor repair and many others. If these belts haven't been replaced in the last 30000 miles it would be a good idea to buy and fit new belts at the same time. New belts are about $30 foryour car although if the belts are not worn and cracking then re tensioning should be the best option initially.

The belts should be tight enough such that you can only twist the belt through a quarter of a turn on their longest running length.

The alternative that may be causing the squeeking though is worn breaks - where the pads have reached the wear limit warning and a metal spring is now rubbing on the surface of the Break disc. In that case you need to change the pads, but the symptom you describe sounds more like loose belt.

Hope that helps.

This type of noise is likely to be a universal joint that is worn out in the drive line. have a shop put it on a lift and inspect the joints.

Jeep Cherokee - Sqeaking Undercarriage

If the "sqeak" is more pronoused while going over bumps, then it is most likely a bushing in the front end. Check your fuel tank straps also, they may be loose. Sounds like this are always a pain to locate. Make sure nothing is in the back cargo area. You can also take your foot and shake the exhaust, WHILE THE CAR IS COOLED OFF OF COURSE.
You can also push down on each corner of the vehicle in the front and stand on the rear bumper to try to simulate or isolate the noise. That's all I have for ya. Good luck.

2005 chevy Impala brakes sqeak loudly

You brakes are no longer any good. Most times, the squeaking and rubbing noises are caused by brake pad wear, but you say the brakes are fine. Otherwise, if by constant rotation speed you mean the squeaking/rubbing noise is present even when the brakes are not applied, you might want to get the wheel bearing inspected.
also check out -------- The most common would be a loose P/S belt. If it is tight but is still the source, it could be a restriction in the P/S system causing high pressure and resistance in the pump.

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub
