My 06 makes a grinding noise on the front end. Its like a once a rotation type frequency. Its worse when turning. Its not the brakes. How do I know for sure that its my CV and which side.

when a CV joint goes bad they usually clunk not grind, are you sure its not an IWE hanging up? or a bad wheel bearing?

 

Also check the easy stuff like the dust shield. Those get rusted out and can bend quite easily into your rotor/hub. You’d hate to take a bunch of stuff off/out just to find that it was a heat shield.

Bearings hum (especially at high speed)
brakes scrape/grind
iwe is a mystery to me
cv clunk and bind

 

pop it in 4H ... while going down the straightaway.. if grinding goes away it’s the Iwe.

 

^yep. a bad CV joint usually doesn't grind its more of a clunk. the symptoms you said make me think an iwe is your issue

 

I would suspect an IWE or with it being a little more during turning a wheel bearing. There are some good videos on YouTube showing the symptoms of a bad wheel bearing. I would watch a couple and see if they sound the same. Good luck.

 

Check the short piece of rubber vacuum line on the right side of the engine accessible through the wheel well. Mine was dry rotted letting the IWE’s partially engage. It connects two of the stiffer solid vacuum lines. If you look on the back side of your wheel you’ll see a double vacuum connection you can just follow that up to the short rubber piece.

Be aware that one of the lines going up from the wheel is simply to get above the water line so you don’t suck water into the IWE when you engage/disengage it so it is open but up higher in the engine bay.
