Before doing anything involved, get a ratchet with the right size socket and a grease gun. Grease the front lower a arm at zerk fitting. 3 or 4 pumps.Then take the ratchet and loosen a little on the a arm bolt. It will spin grease onto the shaft. It doesn't actually loosen anything, it just spins. You can feel the bolt head on the other end of the a arm spinning too. It would only loosen if you put back up on that bolt head. Make sure the other side spins too though! This method worked for me. My squeak was very loud!
