2 ?s How do I "Search" ? What's that knocking?

[Stephen]

I can't find how to search, help.
I noticed my 03 Aluminum making an occasional "knocking" sound.
It occurs at normal acceleration and sometimes even while cruising.
It seems to quiet down at higher RPM'S...

If that left one touches full time, you will hear the most amazing engine sounds. Especially if you're 1000 miles from home.  Don't ask me how I know..
