MX5100 HST HST noise

[horses2]

I have an MX5100 HST that has been very reliable. It has developed what seems to be a bearing noise when in mid range or high range. the noise doesnt occur when loaded at lower speeds and not at all in low range. the noise is different from the trans whine.

all fluids are changed on schedule, using Kubota filters and fluids.

Any thoughts or suggestions?

How many hours when you noticed noise? Are you running udt or sudt2?

update: the tractor has 178 hrs. I had changed the hyd filters and topped off the fluids per the owners manual. I had used UDT. After going thru some threads on fluids, I drained all the hyd fluid, changed filters again and this time used SUDT2. hard on the wallet, but the tractor loved it!! The trans has NO noise, and seems to run alot smoother.
the SUDT2 is hard on the wallet, but the tractor runs GREAT.
