Front Lower Control Arms

[labatt]

I just brought my '03 4.4 in for service (about 60,000 miles). One of the reasons was creaking in the front suspension when turning at low speed. The diagnosis was that the lower control arms are getting pretty worn and will need replacement soon. I was quoted $850 for this, and I was told it wasn't covered under my extended/certified warranty that I bought a year or so ago (which is fine if that's really the case). Any thoughts on any of this? I just want to make sure I'm not missing something here...

By the way - yo to my X5 crew from the Roadfly days... ltns...
