[waterproof]

Hi. Here is some picsture of it, looks like its the drive dog on one of the picture but on anohterone it looks fine, and its the flex shaft that is to round?
Maby the factory have made it to small and thatswhy it just slides into the drifeshaft after 1 minute of driving..
Dosnt seems like the flex is damaged eighter.
Maby i need both thing New, flex shaft and a driveshaft.
On the part list it stands that one of the drive shaft is reverse, how could i find out if its reverse or not on a driveshaft?
