Lubrication confusion

I loved it!  For the first 3-4 battery packs.  Then it got loose.  I opened it up and the grease got all over the inside of the gear case. Even managed to get over to the spur gear...  The DT gear diff isn't sealed, and this definitely was not viscous enough to stay in.

It might not be enough for a trail truck; I put my car on a piece of narrow wood, to see if one wheel on the ground could drive it off.  Not stiff enough to keep the other wheel from spinning.

Thanks, you just saved me from making a big mess of mine! It sounds like roughly the same behavior as the thick grease I've got in there. A couple runs in, the effect disappears.

Guess I need to start researching putty or clay, I think it's gotta be much stronger and longer-lasting than anything I've tried so far.

Try using a silicone ear plug - mega cheap, and surprisingly effective in diffs that aren't properly sealed!

Even cheaper (free) I jammed a scrap piece of aluminum rain gutter inside the diff as a shim. I figure the soft aluminum would get destroyed long before the steel side plates and gears.

I need to test it still, but it's way tighter than ever before. Might even put another piece on the other side to stiffen it up further.
