According to the manual the front 18mm bolts (and two nuts) are required to be torqued down to 118 ft lbs...
According to my Craftsman wrench I went all the way to 110-115 but a couple of bolts didn't reach that much (at least 110) but I stopped for fear of stripping something., I have to recognize that was quite a workout for me.
Does 118 ft lbs seems right? BTW I remember having a hell of a time loosening these guys
