Hopefully these pics work out, and hopefully your trucks don't make any bad noises.
Where did you get those pictures? That looks like some of my stuff.... It even brings back memories of the day my old TD-14 met the big hickory stump.
ouch. spendy stuff, there. i had a ring and pinion try to eat a spider once. at speed. on the tollway. locked the rear end, tore off the drive shaft, and the tail of the tranny. good times!
