P500 Noisy transmission (rear end?)

[Moark Willy]

I couldn't find this addressed anywhere on the forum so here goes.
As I use the 520 more and more the shifting has slowly started to become a bit less harsh.
Today I took it up the road around the neighborhood since it was such a nice day here (80°)
Once the 520 gets up to speed and it is "freewheeling" it gets noisy, like the gears aren't meshed tightly.
It is most noticeable when you let off the accelerator or going downhill on a gradual slope
Usually my uses are around the property rather than on the road so the noise isn't there.
Anyone else notice this issue?

Thanks for the fast reply....it is a bit unnerving though when it sounds like parts are about to fall off.

I know, but they haven't yet .
The P5 is a tank, just not as tight . . .

Straight cut gears doing straight cut things.

Try using a heavier weight oil to quiet it down a bit.

It's not the belt.

My old 700 had diff noise too, I disassembled and checked clearances, all normal. Our new 1000 is the same….
This helped the 700:
