Well I warmed up the GT today and drove it around and raised and lowered the plow blade numerous times and no strange sounds or major leakage.
It's been quite some time since I last used it to move snow when the hydraulics were making a squealing noise and then I just remembered that the oil level was just a little under the 6" mark at that time. So it was topped up to the 5"mark back then, so maybe that's the issue I had. Today I also checked for foaming as Dave recommended and there was none.
When I first brought the GT home I removed the engine for the rebuild and really wanted to replace the hoses and repair any thing else that looked suspicious but had already used up the budget. So its should be done now. If anyone can think of anything else to look for or change while the engine is going to be out please feel free to give me a heads up.

Rear transaxle oil if not already done .
Good thinking Dave, just put that on the list. I think I read someplace there's a bolt that should be upgraded to a stronger grade. I'll be searching for it in the near future and change it at the same time. Hopefully it's not a difficult task.

Have you looked at the center axle pin? Harry
Thanks for the heads up on that Harry. The po of the GT said he changed that already and I needed to tighten it to stop the play. I think that's probably the only thing that was fixed on the tractor by the looks of it.
When the engine is removed is there anything back of, around or under that I should be looking for that's easier to replace when the engine is out of the way? I remember seeing worn travel linkage that needs attention.
If anyone could pass on more ideas I'd appreciate it, thanks.

Im thinking your talking about the ones that bolt the gear halves together in the rear end.
On my 648 and 446 I just inspected them and made sure they were tight.
I think you can just see them on the left on the big gear.
If I remember there are 4 of them.

Wow, that's the kind of suggestions I'm looking for. Thanks Dave, you're the best. That is probably a good thing to change and is now on my to do list.

Thanks JSinMO, that looks like a pretty tight area to get tools in there. Should I do a diesel fuel rinse prior to new oil change? I'm thinking I remember a post of Eugen's about doing this very process.
