What should I check out next? To my knowledge, all the suspension is original.
Thanks for your help!
P.S. I don't know if this is related to problem, but the left arm was a lot more difficult to install than the right. My procedure was to screw the front bolt to the chassis and do the coffin arm bolt last. On the left side, the trailing arm did not line up well with the control arm—it was about 1/8 to 1/4 inch too short and required a bit of force to push the control arm and trailing arm toward each other to get bolt through the hole. The right side needed some nudging, but very little and was pretty easy to do. I don't know if this means anything.

IIRC mine was the same way. And, like you, the sound got better but didn't go away. Pretty sure my struts are shot. I replaced the drop links at the same time I replaced the trailing arms. Sway bar bushings are on my list to replace as well.
