How hard is it to change out a yoke? I was driving down the road 40-45 mph and my truck starts shaking. i pull over and my yoke is leaking,bad. so i turn it around and head home. So im thinking/hopeing my gear and locker arent messed up. and hope its just the yoke. i think when i took a leafe spring out i messed up the pinion angle and then the yoke. and ideas suggestions? i have some pics,but thyre crappy.
