stab bushings

I had some front end clunks over bumps with 97 caravan.I changed both tie rod and was lot better , so tried to change swaybar bushings.I only changed passenger side , and it seems to be worse is that because I replaced only one of them.Also which way do they go on as there is a squarish end, wonder if I put on wrong.
I plan to do other bushing tomorrow (the hard one , any tips) and also end links any tips for this also, I assume bolts tough to get off.Thanks

never mind , figured it out

Changed end links , both tierods, and passenger side swaybar bushing - no more clunking
