Hi:

My 2305 with maybe 140 hours on it seemed 'rough' and a little noisy in 4wd also (worse on hard surfaces). Not horrible, just lounder than I remembered. I changed the front gearcase (First change unless the dealer had) and put synthetic gear oil in it and it quieted it down quite a bit. I saw a few metal filings come out but nothing major so I think maybe it was just in need of a change.

Question for someone that might know? Do the extreme pressure additives (Phosphorous, etc.) they put in gear oil break down over time? I so how long?
