So I find out both rear differential seals are leaking...
My thinking is to change it all..
Upper control arm
Lower control arm
Shocks
Seals
Axels
Am I missing anything, I'll include pictures if I can figure out how to upload.

Thanks Lou
Ps. Do I need a four wheel alignment after. Any tips or tricks...

Morning Lou. Glad to see you got the images figured out.

Went to the Rock Auto website and they had several listings under the category, "Differential Rebuild Kit". Rock Auto

If you click on any of the items shown in that list, it gives a listing of all the parts included. After looking at the photos, I would probably change out the shocks as well.

As to your question about the alignment, if it were me, I would probably get an alignment after replacing all those parts.

Thank you great information...

First, clean the area real good. Some simple green and a pressure washer at the car wash. Check diff fluid lever and top off as necessary. Now check for leaks.

Wow!
based on the corrosion I am seeing, I would take a wire brush/wheel to everything undercarriage, and use a can of 'rust converter' liberally on any exposed metal. I would also inspect your entire frame/sub frame… I am guessing you live in the rust belt?

are the seals leaking at the pumpkin cover, or the input shaft? BOTH?!
Replacing axles is expensive, I would clean them up as aforementioned.

you can have your alignment checked(An alignment check is usually free at big chain shops),
which will tell you whether upper and lower control arms/ball joints/tie rods/hubs/bearings need to be replaced.

If not out of tolerance, then don't replace!
Clean it all up. If you have access to a sandblaster/booth, I would go there and sandblast your entire undercarriage...
under coatings today are much
more effective than they were in the early years.

thinking about the pinion shaft seal, sometimes removing the yoke allows for easy replacement of the seal…
Sometimes you have to disassemble the pumpkin to set input shaft crush sleeves.
