See the boots gone on the sway bar end links, and the LBJ (Lower Ball Joint), so likely the UCA is the same.
I am going to say...every suspension and steering component with a bushing, ball joint, or boot. On the front, UCA (Upper Control Arms), LCA (Lower Control Arms), strut rod bushing, swaybar end links, swaybar bushings.
Can't really see the outer tie rod ends, I have never really dealt with bad inner ones.
In the rear at least the swaybar end links.
My 89 was nearly as...grungy and a couple of pressure washes later I no longer get so greasy doing simple things, and i think I fixed the oil leak (cork gaslets on the ends under the lower intake) and it really hate working on greasy cars any more.
