[QUOTE=911monty;479191The reason it is installed with the nut on bottom is so that if the nut were to fall off, the bolt would still be in place. With nut on top if nut falls off bolt also falls out.[/QUOTE]

Theory is correct, but nevertheless factory installs them with nut on top … and plenty of thread locker to keep it from coming loose.

New factory bolts do not arrive with pre installed thread locker, so apply some when replacing.

There is factory applied thread locker on the front end bolt, too. Theory would have it, you chase the threads on captive nut to remove old sealant first.

I’d use new nuts and bolts for this job. Just good practice and also saves cleaning off old thread locker.
