That’s what I would have guessed. Poly graphite are very tricky to fit to allow proper rotation. Too tight and they bind up badly and the suspension doesn’t work properly, too loose they rattle and clunk. And in areas with temperature change, if you fit perfectly in the summer, they shrink and are loose in the winter. Opposite winter to summer.

After using dozens of different types of poly bushings on various car builds, fitted, special greases, zerk fittings, etc., I’ll never use them again in rotational applications.

Don’t get me wrong, they work fine if you want to stiffen areas like body mounts, subframe mounts, crossmember mounts, etc. non-rotational applications.

Find some fresh outer sleeves and do what 911tracker85 did for a long term solution.
