Lubing my chasis I can only find 1 grease zert on my '97 Expy 5.4L 4x4. I think it was on the drivers side. Is everything sealed here? If there are more.... where are they?

Some people use a needle and inject grease then seal it up with a dab of silicone. The boots looks mightly flat which makes me not real comfortable that they are lube'd enough.

 

I have found 2.
