there's a good write up on Pelican on how to get them back in sync, that's how i fixed my top. dont use the drill method to turn one of the sides, instead simply snap the little clip on the motor and pull out the transmission cable on each side accordingly to move one while the other stays in place. some people ruined the thread on the cable with the drill.

also make sure your rods are not bent at all and are the correct length, they have some adjustment to them.

Good additional advice. The bushings in the arms on mine had elongated and there was a lot of slop on one side which caused binding when one side got behind (even with the motors synched.) Also grease the tracks so it slides more smoothly. That will lower the load the pivots see.
