ok so tonight i was driven the d150 an noticed when i would put the truck in park an go into a store or somthing an go to leave the truck would lock up like some 1 was holding the brake's down or somthing?? well i thought maybe it's just the brake's so i kept driving an she lock's up & am doing 40-45 after sliding to a stop i put it in park an then 1st an i hear almost a whining sound an im not moving, so i put it in reverse an it worked so i got it off the road.. but i checked the drive line an it felt semi tight, not sure if maybe the pin in side the rear gave out?? but would it stive back up??
