Alright so, I picked up a Gen 3 this weekend with a bad coupler. I got a good used coupler and put it on today. Bolt everything back up and now I am hearing a slight noise from the rear of the case when you snap the pulley back and forth. Its not the coupler from what I can gather because it from the rear and not near the snout. You can hardly move the pulley back and forth and it makes the noise but it spins fine and doesn't bind up or make any other noise, was going to sell it to a member on here but wanted to make sure it was going to be ok before I shipped it out to him. Here is a video, might have to turn your volume way up to hear it.
