Mystery Grinding Noise.........
I have a 2006 V6 with 130k miles on it. About 1500 miles ago I started hearing this faint grinding noise when driving. I took it to my trusted indie tech who works on all european cars (he is not a VW sepcialist). They checked the truck through, top to bottom and found nothing. Break pads are good, rotors are good, wheel bearings are good.
I took it back and continued to drive it. Noise is slowly getting worse. I hear the noise constantly. It does not change under breaking nor acceleration. Turning does not affect noise either. I can throw it in Neutral and rev engine while coasting along, noise continues to stay constant. It does appear to increase with speed.
Took it back to the mechanic last week. This time when he test drove it, he agreed the noise is getting worse.
Mechanic believes it could be the front 4 wheel-drive differential.Has anyone experienced any problems with this? Do you guys have any idea what else it could be?
Would love advice. Not sure what I want to do with it
