That sounds like a good idea. i'll give it a try.This is easier shown than explained... but here it goes.
Get 2 nuts that will thread onto the top portion of the stud. Tighten those two as hard as you can against each other not down to the base of the stud. Then hold the nut that is on the bottom of the top portion of the stud with a wrench and use your ratchet to break that bottom nut loose.
Soaking the bottom nut in a little bit of PB Blaster 30 mins before you go at it can make a big difference.
