Poly shackle bushings can be tough to install, first if you didn't use a grease specified for poly bushings, the petroleum that your using may degrade the bushing, so it may fail later on?
put a slight bevel on the end of the bushing end that will be going/pushed into the frame tube, install the bushings on the shackle, put the whole assy in the freezer overnight, then upon assembly, lube the frame tube and the bushing entirely with a light film, assemble quickly while still frozen
the second alternative, is to freeze just the bushing, then install that in the frame tube first, let it thaw to room temp, then install the shackle, either method will work, I generally prefer to install the bushing in the frame first

If you have a large enough vise or a shop press - you can get press them in. Lots of lube helps too, (That's what she said!)

The shackle will move fine- trying to move them with your hand or arm v.s. the mechanical advantage of the suspension is totally different. I have the poly bushings on my Dart - and there are no problems. Had them for 10 years or so.

I think at some point I'm just going to make some bushings from aluminum. Seems like a better idea to me.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Put a bolt/nut through the bushings and tighten nut to pull them into the frame.

Lots of lube helps too, (That's what she said!) Funny! These bushings do squeak too! I greased mine years ago but it is sounding like I need to redo it.

Usually the only reason I find that poly bushings squeak, is that the wrong lubricant (most petroleum products are harmful to the longevity of poly bushings) was used installing them, or the components/bushing were tightened with the suspension at any angle other than at ride height, not tightening the bushings/components at ride height will either result in a bushing with a severe torsion twist to it, or a torn/fractured bushing, either way...squeaks (can happen with OEM rubber components as well) Mike
