What is special tool MB990954? and to clean/repack is this like standard ole bearings where you put grease in the palm of your hand and press the bearing into your palm until the grease comes out the bearings?
Expert:  David Dill replied 5 years ago.
It is for the jam nut, any socket that will fit and remove it will do. Be sure to remove the old grease first. Different greases don't mix well and can actually liquify.
Customer: replied 5 years ago.

I assume these instructions are the same for a V6-3.5 Liter XLT also? the instructions show the ES version in 3.0 liter.

Yes, the instructions showed the same procedure between the two models.
