Greasing M2/112 FREIGHTLINER BUSINESS CLASS CHASSIS.

[Sand-dog]

Hello hoping I can get a little guidance. I service my own freightliner chassis over the years. I’m told that there’s 24 to 26 zirk fittings. I have only been able to find 20. The thrust bearings to the S cams, all joints and ?, does anybody have any ideas where the other possible ones could be?

The number could vary. Most late model rigs have non greaseable steering linkage and king pins. From there going back, check the steering column. If it has u-joints they are probably non serviceable. The spline slip joint should have a grease point. There should be at least two zirks on each brake. One on the S cam and one on the tube holding the actuation rod. Make sure u joints do or don't have zirks. Check the carrier bearing(s). I am assuming air ride so there shouldn't be anything on the suspension. Every time you roll under keep looking for more.
