Hello, I bought used dementor as a roller, put my own electronics, almost everything works fine, car is a beast but i have 2 problems with center diffrential. Center diff have metal 7075 case, new cups and bearings, gears and spur gear are in good condition.
Firstly diffrential locks itself under load. After rebuilding everything seems to work fine, 0 grinding, smooth but as soon as load from drivetrain is applyed something inside is causing it to jam. So i tested it in my hands bit more and i noticed that when i twist diff holdnig by cups everything is ok on both direction, but when im holding by spur gear and try to twist by cup something is jamming. And that jamming is not like bit of grinding but like sudden lock after while without any prior signs. Internal gears looks fine, no wear on teeth, no shards etc.
Second problem is Centre Diff Bulkhead flex at load, part nummber C-00180-018. This hole for bearing in the middle seems to be larger than it should and bearing have to much space there no matter how tight i screw down 2 pieces. As a result when load from pinion gear is applied entire diff goes 2-3mm up in this place but stays in place at the other side where its mounted to motor mount. Then spur gear is rotating unevenly causing damage on itself and pinion gear. At first i thought that plastic bulkhead is old and give to much flex, bought new one and problem is exacly the same.
What is the answer to this problems? Buying set of diff gears, buying metal diff bulkhead? Diff gears are few euros but metal bulkhead is like 35 euro and could have same problems with hole for bearings to large
