Here goes......

OK, I open the inner case that holds the spider gears, add oil put it back together. Now, there should be some oil in the outer housing where the ring &amp; pinon gear are, duh. there's no o-ring or seal of any kind. How much would be good and does it leak all the time ? A little silicone can cure that, or is it suposed to "breath". Maybe I'm just a worry wort, I used to build full size drag cars as a hobby. It's just something with oil in it and without any kind of seal bothers me. Or maybe I'm over engineering this thing.

"Or maybe I'm over engineering this thing"


I thought the same when I refilled my diffs and have not had a problem with loss of fluid but I would think some would escape but it looked like a pretty tight seal and diff fluid or grease is pretty dense so I think you should be fine.

<span style="font-size: small">Does anyone know the amount on theEarthQuake front/rear differentials,and theweight gear oil?</span>

Look at the beginning of this thread...... not much of anything in the diffs...... I pulled all 3 of mine out and filled them as follows:

frt 5000/ cntr 7000 (but 10000 would be better) / rear 3000.... justfill them up but not all the way so as when you close and tighten it up it won't spill out. Just be easy on the screws beause they can strip easy........

sorry thought this was the other thread check this one out ..........

Ipack mine with Red grease it oozes out the bearings and helps them last also

You need to do my differential modification using a tornado pinion gear they will last for a long time.
