I posted in the EB48SL thread but as I'm building 410.3 too thought I would put it here as well being both threads seem to get different visitors,

In the process of putting my EB48sl and 410.3 together at the same time, these are my first Tekno builds other then helping buddies on occasion. Anyway all 4 front and rear diffs seem to want to go in the housings with only one shim on the gear side of housing for best mesh, both on gear side and it is too tight and one on each side doesn't feel right either, once in the housing and tightened up they feel pretty smooth for being new so I'm guessing I'm OK? Both center diffs feel crunchy when fully tight, back off screws just a touch (like half turn) and they both free up......normal? Also noticed when the droop screws are put in the arms all the way that it tightened up the hinge pins on the arms and had to ream the arms some more to get free movement. Just looking for some clarification that I'm going about everything in the right way being my first Tekno's. The kits seem quality and I'm happy so far just trying to learn them. Thanks
