im having a popping noise from the front end when in 4wd ,i read on here that its caused from the chain becoming stretched, and jumping teeth.was just wondering when that occurs will/or does it damage the teeth on the gears to the point replacing the chain would be useless? hoping to get thru the rest of this season of mud bogging, with just replacing a chain on it if possible ,also has the pt conversion in it if that matters.then this winter i'll put in a 205.:D
