Identify this noise please...
'05 Z-71 crew-cab 5.3 appx 56XXX miles
When I turn the steering wheel (left or right) while moving, there is a knocking noise that I can feel through the steering wheel. Sometimes it is louder than others and on bumpy roads it gets bad. Is this a bad tie-rod, ball-joint or somethign else. I admit that I don't know jack mechanically so I don't want to get bent over when I eventually take this in for repair. Thanks in advance for the replies
Wow! I finally caught a break...
A big +1 for my original dealer Freedom Chevrolet in Virden, IL. I called them and they are going to replace it free of charge on Friday. I am 20k past warranty so this was a surprise, but the 40 minute drive will be worth it. I'm going get the old ISS back and drill in a grease nipple for likely later use.
Again, thanks to all on this site for the knowledge shared. I'm sure I'll be back.
