I have a 1995 Chevrolet K1500 and when I’m turning left at low speeds I hear a loud clunk noise. Can pinpoint where the sound is coming from. Any idea what it may be so I can take a further look and replace it?Thanks for any help in advance!

 

could be several things. Bad front axle, bad suspension, bad transfer case ....
have a helper drive while you observe from outside, or duct tape an old smartphone to it to record video.
