I have what I believe is a 1991 Big Bear 4 x 4 (not sure about the year). I can seem to figure out how to get the swing arm bolts out. There is a nut threaded on the end, which I removed, then the bolt itself if threaded on the outside. On the end is a hex head hole. I put a alum wrench in it and tried to turn it, but just bent my alum wrench with no movement of the bolt. I need to replace my missing swing arm boot, and need these pivot bolts off. Any tips would be appreciated. Thanks

 

Once the nut is loose, the bolt should screw out with the allen wrench. These bolts can be very tight. You may need to get a better allen wrench or use a little heat on the frame. Be sure to put never seize on the bolts when you re-install them.
