Just not convinced that diff screw or nut are the issue here, had them out and they thread up to each other fine, havent stripped or anything crazy.
Any other theories?
By the way, if i hold the diff in my hand and fully tighten up then then twist the outdrives in opposing directions for a few seconds the not lossens and can be seen to physically move up the channel a few mill and the resistance gets less and less.
Maybe it is screw and nut!
