I dropped the haldex oil and it was like gravy.. took the pump off and the gauze was covered in gunk as was the inside of the pump. So it needed a service, but that wouldnt cause the noise.. just the haldex to fail. Drained the diff oil and it was as golden as the sun. Im guessing that the previous owner had it looked at and after a dirty, oil change with possibly some filings they decided to get rid rather than spend the money trying to fix it.
Started into removing the diff before the weather got to miserable and I called it a day, but I have a few queries.. in order to get the subframe down is there access to the top of the bolt that holds the diff up? or is it in its own housing so that when you take off the note the bolt doesn't spin.. I checked the boot floor and couldn't see any access.
any other tips from someone that has already done it before would really be appreciated..
