Replace Knuckle Coupler on F7 Rear end

[plint]

The coupler is broken off and how do I open the coupler box to replace the coupler?  I don't see a screw.  It looks like I need to pry a piece off.  I don'y want to mess it up,,,,,,,,,,,,,,so any help??
Thanks

There should be a plastic clip holding the coupler in place. You need to gently pry each side away from the coupler box until it disengages. Then you will be able to remove the clip and coupler. Snap back into place with the new coupler.
