The link above the diagram is "live"...in that if you click it, you'll go directly to the diagram and part nbr index. At the top of that page...you'll see the "links" that got me to that diagram...if you go back one link, you can select other diagrams...for the front axle...actually everything on the vehicle if you go back far enough.
For example, this is one link back to the main group/subgroup for the 4.4...scroll down to the last diagram (for wheel bearing kit) and click on it...and that diagram will explode into a larger view along with the part nbr index for everything in that diagram:
