Argh.. These bearings won't fit the E-maxx gearbox!

There are 2 versions of diff & diff case, the newer version of the Tmaxx & emaxx diff uses a different sized bearing on one side, rather than 2 bearings the same- here:



Emaxx 3903/05/08 new style:

Uses a 8x16x5mm bearing & a 10x15x4mm bearing

Emaxx 3906 / T-maxx 'Classic':
http://traxxas.com/sites/default/fil...nt-pro15_0.pdf
Uses a 10x15(x4mm) bearing on each side of the diff cup.



Im guessing if one of your bearings wont fit then you have the older diff design and a 'new' diff cup- seems that way based on the design of your t-maxx and it's driveline ( old style knuckles and driveshafts etc ).

I would suggest you grab some new 3903/05/08 diffs from ebay to use with your alloy diff cases.
