Q&A

I was told by a mechanic that my 2nd gearbox in the back drivers side is the cause of my car making a loud hammering sound. But this was after he told me it was a differential? He also mentioned something about pins going out? I'm the worse person to speak car terms with:-(I don't know if the three things work together or connected in any way but he came back with a quote thats more than my mortgage. The hammering sound comes on for about 5 seconds then it'll stop, all you hear after that is the sound of grinding brakes. He went on explaining that the pins where the brakes rotate were out...I couldn't make any sense of it. What could my problem be? Is it possible that it's just the rotors that I need to replace? Or it is something that I could maybe fix on my own? Is a differential tied to the gearbox and pins at all? Any help would be greatly appreciated. Thanks in advance for all your help.
