You also want the upper joints changed, correct. Seeing you're doing this I would have who ever does them sand blast and paint/power coat. I know of a power coating place in Tennessee that races Mopars. They might be able to do the whole job for you. When you work on something you want it to look like you've been there and show all your hard work. And I'll tell you I would always pay a premium for a Mopar with a good front end.
The entire front suspension is being rebuilt. I already have the parts. When I pulled it apart to Install the headers, i took a rubber boot off and there was only a very small amounts of brown crud. No sign of grease !!
Apparently the suspension was rebuilt and never greased , of course the seller told me it was rebuilt.
