i have a 1999 new style 1500 and i had one hole in it about 2 months ago. i patched it with cylicone (JB weld didn't work cause it got punched out"
) the 4x4 worked perfectly still but now i have a couple more and aparently i think the chain in it has stretched out and is punching holes in it and in the newer models of trucks they have a tin shield in them to prevent them from stretching, i was wondering has anyone else had this problem?
