You can do what I did, I took mine, and drilled and tapped the outer shell for the bushing for a grease zerk fitting. Then drill a hole down through the bushing once its in the control arm, and install the fitting. This will allow you to get grease down to the inner sleeve, and help with wear and squeaking. It should also free it up. You don't want them loose either.
