Post subject:  XB808 Questions to spare parts for diff

Hi all,

I bought a used XB808 and I wanted to fix my front diff. For this I wanted to order pinion gear 355111. But this part was replaced by 355113. So I ordered this one and the aluminium collar 352077. But the collar is bigger than the ball bearings and it doesn't fit into the diff housing. What did I wrong?

I know this is a late reply, but if you are still using your 808 and continue to have problems, I eliminated this problem once and for all on the 808 (2008-2010) here: viewtopic.php?f=9&t=12537

The official solution (adding another bearing) sucked as much as the original design, the only proper fix is to use a pinion with a smaller (conventional) shaft so that a much more durable bearing with larger balls can be used.

They obviously rectified this from 2011-onwards by going back to the conventional design, but the 808 was a strong car apart from this problem. Mine's still going on the same diffs, 5S brushless converted.
