Guys,
Forgive me, I am new just tonight. Had 430s for years...now have a 460L AWD with 155K .
I am hearing definite slight 'puttering' noise at my LF at lowers speeds going over slight bumps, right turns, or driveways etc. Is this likely a wheel bearing problem? I was told you CANNOT re-pack wheel bearings on a 2010 460s, is that correct?

No, you can't repack the wheel bearings. Those days are long gone. Try raising the car and spinning the wheel listening for any unusual sounds.

 

what’s puttering that description sounds like an exhaust noise being described does it sound like a loud exhaust that you hear when you give gas and goes away as it gets into the higher rpms

 

no its definitely in the front L wheel or shock very focused on LF only . slight rumbling, puttering.

 

Your description of puttering describes what my car sounded like. With the windows down and head out the window the noise was completely different. It was only noticeable at low speeds over small expansion cracks in the road.
