check for play in the distributor sometimes the slop will make the pick up window under the cap will hit the distributor cap , the squeaking noise may be your belt or tensioner pulley bearing the knock can also come from a bad tensioner as well .
The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.
You can check the hub bearings very easily by jacking the front of the vehicle up and shacking the tire from top to bottom and seeing if there is excessive play.If there is then you know it is a bearing if not then you know you have to look deeper.
