@Massey165 I don't have an ES! I wish.
I went and bought some 8.8 grade M14 thread, and now I have no money. Had to buy 1m, but only need 20cm. $80 😭
But, sure enough, with the much improved tensile strength of the bushing extractor, the remaining bushing popped right out.
Threw everything back together, adjusted the handbrake as I'd been meaning to do it for ages anyway, and took Momo for a test drive and, my god, what a difference. The harshness in the rear end has evaporated like magic.
So, at this point, the rear suspension is completely done ✅✅, at last, with every bushing now refreshed, along with the shocks and springs. The panhard rod is urethane but everything else is OE-spec rubber.
In the front, I still need to replace the front control arm bushings, as well as the sway bar mounts, which will happen in the next few weeks.
