So I have been having a banging noise coming from by back tires, and I thought it was the viscous coupler. I have a 2012 Outback 6 Speed MT, with about 123000 miles. I attached a GoPro to the bottom of my car and recorded a video of the two u-joints. It is important to mention that the videos are from the same drive route to keep this test as controlled as possible. In the video it seems like the rear u-join it locking up while the front spins pretty evenly. The question is: Is the banging because of a bad u-joint? Or the viscous coupler?
I recorded the front u-joint by the coupler: Front U-Joint
Here is the rear u-joint: Rear U-joint
Either way, I thought these perspectives were pretty cool. I hope they help anyone who has had similar problems.
