Hi Jeff,

Getting the nut out of the outdrive can be a real pain in the ass. I've had this before with my old Losi, but never with the D4.
The only way I could get the nut back off was with much blood, sweat and tears and swearing... I used to get a flat bladed screwdriver which had a blade about the same width as the flat on the nut and push it down the outdrive. This jammed the blade in the gap between the flat on the nut and the outdrive. You are then able to gently turn the diff screw.

To dissolve the threadlock to make things easier. Try soaking the nut in acetone or WD40. This usually softens up the threadlock sufficiently to make the removal easier...

Threadlock on the diff nut. I use Loctite 251 (Blue). I put a drop in the nut and leave for 10-15mins to go slightly tacky before I assemble the diff. This stops the threadlock getting onto the diff half when you put it together.

I've not had a diff nut fail since I started running the prototype of the D4 back in Feb.. It still has the same nut holder although I do run the Edit Ti diff screw ED050010. It's stronger than the stock item and adds extra piece of mind.

Hope this helps

Adam
