Information presented here is taken from the August, 2001 edition of Freightliner's "KNOWING YOUR CHASSIS". Note that some of the information presented here does not apply to the Freightliner XC chassis.
Greasing your chassis yourself is pretty easy. However, follow good safety procedures. If you use your hydraulic jacks to raise your coach so you can crawl under it, be sure that you use jackstands of sufficient size, just in case the jacks come down unexpectedly. Also, if the rear wheels are off the ground, there is nothing keeping your coach from rolling away. At the Freightliner seminars, Freightliner has stated that most owners tend to "overlube" their chassis - pumping in too much grease. Be especially careful with the Slack Adjusters as you do not want to get grease on your brakes!
If you have someone else lube your chassis, you may want to take a copy of all these grease points with you as they will certainly miss some lube points otherwise.
Here is a pictorial that will help you find the grease zerk fittings with the table below: NOTE - The D does not have Independent Front Suspension (IFS), so you need to ignore these zerk fittings. Click the image for a larger version.
