I have a vibration in my rear diff on my BX2230

Hi everyone, I noticed this vibration a few weeks ago while covering up a under drain I put in on my house site. I went to the Kubota dealer and got an oil change and filter. I drained all the oil out today, then I checked my strainer filter. I found a lot of metal cuttings in it. I got my magnate out and ran it up in the housing and got back some bigger cuttings a couple looked like the curly shaving you would see while drilling metal with a sharp drill bit. I cut the oil filter open and found no filings in it. I strained the old oil using linen clothes and put it back in and parked it in the shed. Tomorrow I will take my mower deck off and my FEL, and bring it into my garage. I've never taken a hydrostatic transmission and rear end apart, but I'm not afraid to. I have good mechanical skills.
My question is has anyone here had such a problem, and if you did what did you find out it was, and where can I get a service manual for my tractor.
If anyone has taken a 2230 apart you would be a great help to me in speeding up the process, and keeping me from making any mistakes, and I would be greatly appreciated for you wisdom and help.
Thanks from Kentucky
Mark

No help on taking your BX2230 HST apart, but out of curiousity, is, or was, your differential lock working? Do you use it alot? I've seen quite a few reports of the fork hanging up or breaking off in the HST. If it's still operational, try using it going slow and in a straight line to see if it's still working. If you have no resistance on the lever while trying to engage it, that might indicate it's broken. Good luck either way.

I just used my diff lock the day before I posted, so it's working. I appreciate the impute though. When the weather get better I'm going to tear into her and see what's going on.
Thanks
