Introduction

Unlike other replacement guides, you will need an additional tool besides the iFixit toolkit. A bearing puller is required and it can be found from any local hardware or auto parts shops for a cost of approximately $30.

If the tool is spinning slowly or not at all, it might be because of the bearing. This guide will explain the steps needed for replacement.
