So I was hearing this clinking sound, got it checked out. I was told it was the drive shaft and it needed the central support. Got the drive shaft fixed only. The next question i asked was if i still here that clinging noise what else could it be and the independent mechanic said it could be the differential fluid, i took it somewhere else and had it changed. I used a synthetic mixture with the right weight and it's still making this noise. I'm wondering if i need to change the rear ball and joints. Can any one decipher this problem or direct me to a mechanic. I'm in the South Bay zip code 90260.
