Removal Procedure Head restraints are the double-post type that are adjustable either up or down. Only the solid type head restraints have serviceable trim covers. Removal of the head restraints can be accomplished by using the J 42372 or by fabricating a similar tool. Raise the head restraint to the full up position.

At the same time, hold both of the tools (2) down and lift the head restraint upward in order to disengage the detents (3) from the guide (4). Lift the head restraint out.

Installation Procedure

Push the head restraint to a full down position in order to install the head restraint posts (1) into the guides (4). Raise the head restraint in order to ensure that the restraint stops at the detent (3). Return the head restraint to its original position.
