Removed all the food from the freezer and most from the fridge before starting. Tipped fridge back until I could place a 2 x 4 a couple of inches behind the front rollers. With the front of the fridge now approximately 3 to 4" off the ground you can remove the adjusting bolt and the roller assembly can be pulled out of the brackets. Slide out of the notches where that hold it into the bracket. Same to install.
