So ive been getting a lot of wierd noises out of my driveline. This an an A4 btw. When i shift it into gear at a stop the car will make a rubbing type sound (you can feel it too) i was getting viberations out of it also on the freeway around 70..... I have determined that to be the oil in the rear diff.. It has been replaced. Also when i get on it, ill get a popping sound or 2. Thats from a stop. ill also get a viberation and wierd noise when under hard acceleration from a roll.. I dont know what is goin on.. i figured id post this cause MAYBE just MAYBE someone might be able to help me with what little i have provided here.. What do you all think i should do at this point.. U Joints are good i checked em.
