I have sent the following to associated support and thought I should probably post it on here also...

If anyone has any ideas please let me know.

Tks

Dear Associated Support,

I have two SC104x4's and I seem to be having a problem with the diffs
in both trucks.

One truck has around 10-12 packs thru it and it appeared to be loosing
diff fluid out both diffs thru the out drives. I have disassembled this
truck and found both diffs with VERY little fluid, not dry but little
oil. Because I was warned to check them... they were filled 3 weeks
ago, when I was assembling the trucks. Additionally because this fluid
is contaminating the the bearing and attracting dirt about the bearing,
two of the 4 bearings seem to have grit in them. I do NOT think this
would be a problem is it were not for the diff fluid seeping out and
attracting dirt.

As a further note the out-drives on both diffs seem to be wobbley and
now seem to fit loose into the diffs

I can't tell for sure, but the second truck also seems to be getting a
dirt build up behind the out-drives (I can't tell for sure), with just
4-5 packs thru it..

Additionally I have checked my parts list and "O" rings do not seem to
be available EXCEPT if I buy a whole diff rebuild kit.

I sure hope this is a mistake and the "O" rings are available separately.

I really like these trucks a lot, but at this point I am VERY concerned
about this diff problem.

As you know the truck requires almost a complete tear down to get to the
diffs to service them and to deal with the bearings. It is ridiculous
to think I will have to tear these trucks down after every 10-12 battery
packs for this service.

Again I really like the way this truck handles, and have two of them
running and another in the box....not built.

I sure hope there is a easy solution to this problem.

Thanking you in advance for your time.

I am going to post this to the SC104x4 list also...maybe some one there
has an idea.
