This has been driving me insane. Noise starts at 17 seconds or so, you can really hear it 17-25, and then on and off after that as I am driving around the block.
It sounds like metal on metal rubbing, but I am not sure where from. Leaf springs or u-bolts?? It has brand new shocks, driveshaft has been greased well... I am out of ideas.
Bonus under the truck shot of all my exhausts on the two WRXs in the garage.
