Losi 8 diffs
small video showing the diff locking up.
Is it due to wear in the case or the gears or both?
Have greased the outdrive shafts and assemeled diff without oil but still pleanty on the gears and shafts.
If I press the outdrives into the case all is fine. If they are free to float they lock up but only from the casing output side.
The diff wasn't leaking oil so seals would appear to be ok.
Everything spins freely when not assemled as a complete diff

My guess would be the case, check to see if the case has a notch in it were the cross pins rest. That's why the came out with the HD diff case.

Check your sun and planetary gears also and make sure the teeth aren't too worn or chipped, that could contribute also. I put the HD cases in mine a awhile back just to make sure I didn't have issues. Be sure you get the metals inserts in the right way.

Servo saver spring/nut position?????
I've searched and found a few references in this thread but......
The servo saver nut! I can't find anyway to tighten the nut all the way then back it off 2.5 turns. Short of Herculean strength or mechanical assistance, that little nut won't go more than a thread or two past the base of the tube.
Should the nut be screwed flush with the tube, then backed off, or definitely all the way to compress the spring, then backed off?
Does anyone run the nut so it sits below the tube, or will that not provide enough tension for the spring to hold the steering arms together? I'm paranoid that if it were to be any tighter, the first decent crash would see all the force transferred straight to the servo, breaking it.
* I should have made note of the original position (race roller) before disassembling it to replace the bearings!!
Thanks in advance for any help!

as long as the tension is there....it should be fine...but from personal experience...i know 1-2 threads is too loose...you need to get some Pliers and crank that nut further....dont worry about gouging it up too bad...you can always replace it.
