Not only was front axle loosely assembled, they didn't put the rubber band on the locking mechanism of the differential … No wonder the whole thing jammed up.
Ended up taking the whole assembly apart.
Balance: 5 cross threaded screws, and about 50% not tightened. The actual gear mechanisms were properly assembled.
The tool provided by them is perfect for removing and re-inserting the bearings.
Most difficult part in reassembling was the metal clamps that holds on the rubber boots.
The whole thing, from start to finish took me about 8 hours.
