When I drive my Toyota Tacoma 96 Xtra cab 2.7L I get a hideous squealing/screeching in my front left front end as I turn and sometimes when I am driving straight down the road. When I turn right and alleviate the weight off of the front the left of the truck the squealing subsides.

My guess is a belt or something else.

Can anyone help me?

 

Does the noise change with engine speed or rolling speed?
Do you have manual hubs?
Have you checked the wheel bearings and suspension?

 

When you turn right, you load up the left side and unload the right side. Check your brake pad thickness.

 

When your turning you most often brake as well

Brake pads shot??

Most times bearings growl more then squeal but who knows.

Power steering belt old or loose ??

 

Brake pads either worn or sticking.

Inner fender liner coming down and rubbing when cornering

Power Steering belt or pump that is getting resistance when you corner.

Does the sound change if you apply the brakes?
