well i drove the truck down to Corning to see my brother (100 miles one way) and started to get a vibration about 2/3s of the way there. pulled over checked all the obvious stuff and everything looked good so i continue down. get there and we go wheelin for a few minutes and go home. SO then i hit I5 comin home and as soon as i get to redding the vibes get REALLY ad so i pull off and get out and theres gear oil sll over the under side of my truck. i dont know yet if the pinion seal and bearings gave it up or if the gears itself are toasted. gotta go pull it today
