TL;DR - clunking noise, doesnt appear to be suspension, or any loose driveline bits (guibo, diff input/output flanges)
I have this weird clunk whenever I step on the gas coming from the rear. At first I thought it may have been my trailing arms as I have the weld on kit, so maybe they were getting loose...this doesnt appear to to be the case.
Whenever I shift from reverse to 1st I hear a clunk coming from the rear of my car. As I'm driving if I let off the gas peddle and coast for any distance and go back to step on the gas I hear the clunk. This makes me believe its in the drive line - loose giubo bolts, loose d/s to diff bolts, or loose axles, however it appears everything is tight. If I'm going downhill and put it in neutral and step on the breaks, nothing (which is why I'm suspecting the diff). My dad said something about it being inside the diff...worn gear or something that is causing some slop.
ps. I jacked my car up and drove it from 1st to 3rd up to about 40 mph and there was no noise, during shifts, letting off the gas and re-accelerating, or shifting into reverse/1st.
any help as its getting annoying and I don't want something catastrophic to happen. I'm going to swap my sisters open 4.10 in over the weekend and see if that helps. If it does turn out to be the diff, what is wrong with it and how can I fix it aside from buying a new diff. (fluid is full and less than 1 year old - motul synthetic)
if this is more appropriate in the driveline thread please move, couldn't nail it down the cause so I didn't post there
