I just had this problem and it was because I changed the brakes and the new rotors where touching the lower ball joint heat shield. I just had to take a screw driver and bend the metal heat shield just a little and the squeal went away
This could be a number of things. If the sqeeking happens when braking, then you probably need brakes. If it happens while driving, accelerating and turning then it could be the belt that is making noise. This can be due to a loose belt, worn tensioner or power steering fluid low or power steering issue.
yo shaft
Ball joints.
Does this squek vary with speed? When stopped and turning right does it squeak? More info is needed
Steering wheel and brake pedal.
A single knocking noise when braking or turning can be caused by a faulty axle. The cost of replacement is usually around 1,000 dollars.
There are two possibilities when it comes to a squeaking sound when turning. The main reasons are a bad power steering pump, or a steering linkage issue.
mine is a 2001 QX4 with the same problem. as far as i know, it could be a bearing problem.
Maybe a bearing is going, a balljoint, or maybe your brakes are catching.
Sounds like your suspension joints are dry or worn out.
probably not the alternator if it happens when only turning its gotta be the power steering or steering rack make sure everything is greased up could be the PS pump going out
possibly your wheel bearing is on its way out
