Yes, not that hard if got a vice or press and a Sawzall.
Here’s the general procedure. Pics below are of lower control arms but the uppers are similar, just smaller.
1. Drill multiple times through the rubber bushing to weaken it.
2. Press out the center of the old bushing. You could probably do this with a ball joint press kit if you don’t have a shop press — for the smaller UCA bushings. The larger LCA’s probably require a shop press.
3. Use a sawzall to very carefully cut the metal sleeve. Once you cut through, it can collapse inward and you can remove it. Tapping the sleeve with a screwdriver and a hammer can help release it.
4. Hopefully you don’t cut into the arm very much with the sawzall. A few light marks are probably inevitable and it will be fine.
5. On the old JBA upper control arms being rehabbed: If you need to drill and tap for grease zerks, do that before installing the bushings. The new style JBA bushings need consistent grease so having the grease zerks is not optional like it was with the old rubber bushings.
6. Install new bushings. Clean the inner surface well and be sure there are no sharp edges. The new style JBA bushings don’t have an outer metal sleeve like the old bushings did.
For the JBA upper control arms, the new style JBA bushings look like this once installed.
Be sure to follow the instructions carefully as the outside half of the bushing is thicker than the inside half.

If you do accidentally get a little deep with the Sawzall like I did
. You can fill with jb weld and file and it back into shape. Good write up Ifhoward! Probably didn't need to drill the rubber with your mighty press, but it sure doesn't hurt.

Good idea with the JB Weld!
