How many grease fittings on 2003 Wrangler?

Not very many if at all. Almost all of the newer models are self contained pre-greased units. All the places to look for fittings (if they are there) are: upper and lower ball joints, center of all four u-joints, and where tie rods meet each other. There are four fittings in my 95. That's about it.

On a 1990 there should be 3 on each side for the front & then one on each end of each drive shaft so total = 10.
