Does this squek vary with speed? When stopped and turning right does it squeak? More info is needed
A Trailblazer that squeaks only when turning to the left could have a problem with the steering or front wheel bearing. Turning to the left puts the right pressure on the parts to cause them to squeak.
The squeaking is caused by friction between two objects that only contact each other during the turning motion of the car - in this case, in the leftward direction. This is an easy fix - stop doing it.
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
when turning or when ridin?
Directly under the hood on either the front right or left side. Most likely on the right.
water/friction
Bad right front wheel bearing.
You have a failed front wheel bearing. Probably right side.
Possible bad front end part.
Turning right loads the left front wheel of the vehicle, so if you hear the knock when you turn right the bad CV joint is on the left, and vice versa.
most likely it is a cv joint going bad, but it can also be a strut tower, or a tie rod... front right strut
On the LW200 it is in front of then right front tire, just behind the bumper. It is small, about the size of your hand.
