So Im not sure what the problem is. When I turn, or when i let off the gas and let the car slow down on its own, and just recently today when i was driving on the highway about 65-70 for more than 15 minutes, the front end of my car makes this disturbing and harsh cranking/grinding noise. today on the highway it gave me quite a scare as the car kinda jerked. I thought it was just a steering rack boot leaking fluid but i put fluid in the other day and when i checked it after the highway issue, it was still at the level i filled it to previously. Im having a hard time figuring the issue and was wondering if anyone could shed some light on the situation. id rather get some honest help from audi owners than go to a shop and have them tell me 20 things are wrong and break my pockets for only one thing that needs to be fixed. any help would be great, thanks!
