Using this Bosch and Siemens oven shelf side rack bushing kit is quite straightforward. First, make sure your oven is turned off and cooled down. Then, remove the old clips and bushes from the side rack of your oven. Simply replace them with the new front and back clips and bushes from the kit. Make sure they fit snugly. As for the notice, this part is no longer available and there's no substitute, so use it carefully. When it comes to maintenance, regularly check the clips and bushes for any signs of wear or damage.
