Denali 05 issues

[nrafie]

Hi guys,

I have a 05 Yukon Denali, love the car. But I notice some issues. While driving and when making right/left or a U turn, I could feel and hear a “clunk” noise coming from the bottom of my floor matt. Another issue is, when I'm backing up, say at the mall parking lot, and I turn the steering wheel all the way to left, it makes this loud grinding noise as if the steering wheel needs to be greased. Has anybody experienced similar problems? Any suggestions? Thanks!

yes - most of us have noticed that. The steering knuckle is a problem. I had my power steering go out in the first 6 months. Take it in for service.
