New Parts needed for this step:
Take notice of the small > & < arrows on the shorter section of two of the posts.
The arrow points to the right on the left post and to the left on the right post.
The back post has no arrow. The saddle bearing is shown below in steps 6.5 and 6.6.
From the front of the unit, the arrows will be visible and point towards each other.
When inserting the posts, hold them firmly as low as possible while inserting them. Torquing them in any horizontal direction can cause them to break.
The back post does not have an arrow. The longer section of the post will be inclined to the front of the unit.
