Recently purchased a minispares 4 pin diff, i assembled it following the instructions given..
all was turning fine with the first output shaft and 4 planet gears in the cage.. with the second output shaft in it started to turn less easy

then with the crown wheel and 6 bolts on the hole diff became locked (even finger tight). neither output shaft could be turned by hand.. this is hardly right ????

i assumed this was wrong so i took it apart and tried again..same result. then tried it with the old fibre washers then without.
no luck.. but noticed the diff turns before the 6 bolts are tightened
more than likely im missing something simple

any help apreciated thanks
