Metallic sound when accelerating at around 55-60 sometimes lower speed

alcgraham · Jun 12, 2019

Ok so I am sorry to keep adding but I noticed today that the metal rattling sound happens when you get over 2000 RPM and gets louder the farther over 2000 you go. So wondering if this could be a loose heat shield? I haven't driven it in the 55-60 mph range again to listen for the clunk noise, I think I might have 2 different things going on. Hope that helps. Also it is driving when I drive under highway speed, shifting, backing just fine. No vibrations, nothing feels funny so I am very perplexed.

So I decided to try to switch it to 4/awd and I drove it up the hill and went over 2000 rpm and no noise! So what does that mean? Also not sure if related I turned on my ac as it was hot and the rear ac unit was making noise like it was breathing, never had that before.

Sounds like a vacuum leak in the front hubs system. Mine was on the right side. The noise is the hubs partially engaging.

So what did that entail to repair? Just replacing the vacuum hose?

Yes just a little hose.
