Hi, sorry for the late reply…just saw this. Here’s answers to your questions:
1. No receipts for these however neither are weeping/sweating. If they needed doing I would’ve done them as they are fairly easy to do.
2. No to these. I might check the pump and see if I can tell if it’s original. It’s operating fine so didnt change it. People usually change them at 60k hence since it operates fine didnt do anything with it.
3. I don’t recall saying there is a rear diff bush issue. I don’t believe it needs doing.
Thanks
