Hey guyz recently my Z has started to make a noise in the rear when I let off the gas and when I shift. It's coming from the rear of my car. It makes a clunking noise that goes with how fast or slow you are coming to a stop. Any ideas what this problem may be? I also have a huge noise coming from the engine bay of my car. It makes the sound while I'm idle(sounds real loud and kinda like a sucking sound)
, the sound is coming from the left side of the engine bay if you are starring at the hood. Thank You for the advice/help in advance!!

 

axle click and vacuum leak

 

rear diff subframe bushing is the clunk.


I know some ppl thnk google is the devil...and is taking over the world, but is surprising what turns up when you turn to the darkside:

My bad bro, and yeah you can have the rockstar tag lol. I made the user id when I first started modding my z. Now I just try to keep her in good condition, and drive her nice an easy. Yeah totally forgot about googling the problem thanks though
