So I saw Redbird yesterday and put it up on jack stands. I watched as Jai sat in it and let out the clutch. The noise Jai is hearing is her differential lifting and bouncing around when it's put in gear. When it torques, I think it is lifting and causing the driver side axle to lift up and pinch a little making the connecting bolts tat tat tat when turning as well as hitting the body. I should have shot a video to better describe it .
I didn't have much room to really check but the Diff strap was not obviously broken and I could not get a good visual on the mount insulator. Those would be my first guess without putting the car on a rack or at least a hard surface. Any one have any spares or any other suggestions?
Driver side U-joint, sorry for the blurry pic.

Back to the throttle issue, I think the next time out we probably need to check out the TPS and the throttle itself as it still has a rough idle when warming up but it revs just fine. It might just need a good cleaning out.
