Okay heres my problem. I was backing out of my drive way and when engage into "R" I hear this Knocking sound front the front passanger side. Then when i put it to dirve "D" and step on the gas the same noise happens. Now i am driving doing 20-30mph i let go of the gas and i hear this KNOCK KNOCK NOCK KNOCK coming fromt he front passanger side. Like something is loose. The sound is faint. I think it may be the CV Joint. what do you guys think? I think i will go to the autoshop tomorrow... And how much does it cost to fix the CV joint i dont know.... I thought my front passanger side tire was going to fall off when i was driving back home...
