Rabbit has taken to making distressing gridning noises when the front hubs are locked. While I was doing the clutch cable I hung off of the front prob which promplty went clunk-crunch. Swinging on it and tugging it about produced more of the same noises and I noticed that the movement is at the input to the diff. I assume a bearing has disentegrated.
So
I'm guessing there is a bearing in there. How easy is it to get the thing out and get a replacement part? What else is likeley to have been nuked? I have a feeling the diff is now empty too.
