I or our company mechanic do the service on my Expy. Under the 15K service checklist it says:

Inspect and lubricate all non-sealed steering linkage,ball joints,suspension joints,half and drive-shafts and u-joints.

Now I haven't taken a look, but I think ford stopped putting grease fittings on U joints/suspension and such a while back. So what is there I can actually grease?

 

There is no grease fittings. Its just a engine oil and filter change and check all fluid levels.
