Mounting Bracket

remove one older mounting bracket & one broken mounting bracket from DW unit (top). replaced the mounting brackets, leveled the DW, using wood screws, secured DW to the wood frame, thereby eliminating the possibility of DW tilting.

Upper Rack Wheel Assembly - This is a little time consuming (maybe 15 minutes), but easy. You will need to remove the entire upper rack assembly before replacing the wheels. After you remove rack assembly and the dishwasher from under the cabinet (see guidance below for brackets), you will see two hex head sheet metal screws with integral washers on the outside of the dishwasher holding the wheel assembly onto the dishwasher. Use the pliers to remove the screws and the old wheel assembly. Install the new wheel and mount assembly using the old screws since the wheel assembly doesn't come with the mounting screws. Mounting Bracket - Pretty easy. Remove port cover for both left & right mounting screws on inside of dishwasher. Remove the screws (if they haven't already fallen out). Careful - they will drop to the floor. Pull the dishwasher partially out from under the counter. Remove the old bracket(s) and install the new one(s). You will need pliers to bend the tabs over to secure them. For the Kenmore, you need to break off the longer end. Slide the dishwasher back under the counter and align the screw holes with the cabinet. I use masking tape to hold the screw on the screwdriver so it doesn't fall off when inserting into the screw hole in the cabinet. Use the flashlight to help see that the holes are aligned. Tighten the screw and you're done.
