Noise on driver side when turning. on 1998 Chevrolet Suburban 1500

I was told to replace transfer case because of noise when backing up in four wheel drive so I did but there's is still the same grinding noise. Now I have a noise in the front like a poping noise I've had the ball joints and and front inspected and there fine. I'm guessing its the front diff but it still goes in and out of four wheel drive fine.

Anyone checked the axle cv joints? Popping noise while turning is a good sign one may be worn.
What is the best way to check the cv joints. Doubt they were checked.
They make a very distinct popping noise, while turning, that's eaisly recognized by an 'experienced' mechanic, best thing is to have one test drive your Sub.
Will do thanks.
U welcom.
