How do I re-attach this part?
Answer George, You best bet is to remove the rack assembly, it'll be a lot easier to work with. Remove nut on bottom of mid arm. This will allow the mid arm and bearing to be removed. To remove conduit, remove screw (some models) from hub. Press tab on side of mid bracket to release the hub and mid conduit. To reinstall arm, reverse procedure. You'll need to remember that the carrier WD12X10114 and the cap WD12X10405 attach to the rack bottom by snap and lock retainer clips.
