Transmission trouble?

[sformal]

Dear all,

Lately, I started to have a strange noise in the back of my golf cart. It is a G-15-A having the exact same transmission than the Utility G-11-A, almost the same than the G9-A, just one shaft is a bit reinforced...

I am not really sure it comes from the transmission but:

1. No noise at all when at neutral;
2. No noise at all when back wheels are jacked up;
3. Noise appears when running and especially if we are several on the cart.

This noise is easily reproducible especially when I slow-down using the "engine braking". Of course, it appears at high speed as well but at any time, can disappear... It sounds like a metal rubbing noise... Not easy to describe or for you, guys, to imagine...

With my experience, I was thinking about scrappy bearings except when I checked the catalog part, there are no bearings at the back trans-axle, only inside the transmission box itself.

On this site, I have never seen any message concerning re-doing a transmission, but is it common to have to change bearings in the transmission? Anyone had experience?

I suspect I would have to change all 6 bearings, 4 oil seals and the housing gasket as well, but would like to be sure before doing anything...

Any remark or thinking?

Thanks.

PS: I would add I checked the primary & secondary sheaves, the brakes, wheels, etc... everything moving and found nothing wrong...

Thank you... no help means something... *smile

The input shaft bearing is probably the one that goes bad most frequently, at least on the Dana G16/22 style trans...

The problem is, those axles never break, nobody ever has to go inside. I been inside that axle only once in the 10 years I have worked at the dealer.
