recently i bought a 99 z71. a couple of days ago i noticed a popping feeling in the steering wheel. when i turn. i notice it mostly when i make a complete stop and turn left or if i cruising down the hwy and turn the wheel slightly to the left. i also notice a slight pull to the right when i let go of the steering wheel. it doesn't matter what speed i run. so that's not an issue. any info would be greatly appreciated.
