Default Back to high pitched noise.

My last post asked about a high pitched noise coming from the rear of my cart.
It's a 2011 EZGO 2five. Yesterday I used a mechanics stethoscope and now I know the precise area of the noise. The high pitched whine is coming from the differential at the top where the input shaft is. I replaced the two bearings and that did nothing. Can't seem to find a break down diagram of the differential so I'm wondering if someone can point me in the right direction to see what exactly is there. Anyone have the same problem and fixed it? Noise is driving me nuts. Noise is only there when torquing the motor. Thanks in advance.

Have you tried turning up the radio?

One recommendation for a whining RXV rear end was to replace the whole input shaft. I did it, but with no success. I ended up after 2 years with the annoying noise by purchasing a brand new Schafer Transaxle which is a dream. Super quiet.

So how much did that new differential set you back?

A 2FIVE differential isn't the same differential that are in an RXV.

Yes, i remember. The 2Five has a different gear ratio and is more expensive. The RXV transaxle was less than half of that...

At 2500 dollars and the 2five being more money I think it's time to try to find one in a cart yard some where if that is possible. Why is it I can't find the diagram of the differential break down showing all the parts inside. Does the diagram not exist? Maybe I could just change some or all of the inside parts and save a bunch of money. Anyone have any thoughts on this? Any golf cart junk yards around?

Even if you could find one on a junk yard, how to be sure, if it's better than yours? Replacing the main parts inside the transaxle isn't a good idea as well.
For example:
New Tansaxle Assy RXV 2016+ = $ 1193
Single parts:
Kit, Int. Gears = $ 1316
Kit, Ball Bearing = $ 168
Kit, Limited Slip Diff. = $ 536

Total: $ 2020

OJO, can you tell me or show me where you got those parts from or a diagram of the differential? Can't seem to find a diagram anywhere.
