Going to describe this best I can, whenever the car is in 6th gear cruising and you press the gas pedal "halfway to all the way" it makes a grinding sound from the rear end which has distinctive sound traits as the famous "clutch buzz". I changed the diff fluid about 5k miles ago no metal shavings. Been doing this since I purchased the car 10k miles ago.




Also while we had the car under the lift trying figure out why the rear end is making a new pop noise after lowering the car on kw v3's; we were playing with the drive shaft and noticed it would get stuck when pushing it back and make a very slight pop noise where my finger is pointing..any chance they could be related?



Thank you to anybody who could give me some insight.
