people who have installed polyurethane bushings...
I got a set of energy suspension bushings recently. The whole front and rear came out simple and smooth. Had a bit of a battle getting the old bushings out but not too bad. But we are now having tremendous trouble getting the new bushings into the control arms. My question is: is there an inner metal lip that you need to remove to get the bushing to go in properly? We thought they might have sent me the bushings because they don't seem to fit properly. We are using a 14 ton press btw.

I was thinking about doing this to mine... How much did the whole set cost? did it include the dtts deletes? and also on a scale from 1 to 10, How difficult is it to replace all of them?

Yeah I was talking about the rear control arms. We got the inner sleeve out once we realized it was there haha. Bushings went in just fine. I got this set:

throughout the range of the rear suspension the outer bushing actually twists, it has to for the suspension to gain camber...
If you have a poly and especially a delrin bushing back there it won't allow it to twist and the suspension will bind.
the only thing I would run is rubber or a spherical bearing
both AWR and MMR make spherical bearings.

For future searchers:
If the rear control arm looks like it has a flange on each end, you did not press the whole bushing out. And changing the bushings out is a major pain to do in your own garage. Especially because you have to drop the rear subframe to do the rear control arms.

This is also a good time to put in extended studs on your hubs since the whole suspension will be apart, Be warned though the rear wheel bearings will need to be replaced, this will also cost a couple hundred more to do.

my entire car is poly bushings and to be honest it transfers bumps a little harder then it used to and it is a little stiffer, but to be honest in terms of comfort it changed almost nothing at least I have not noticed it after 6 months of driving on it. Noise has not really changed either no real squeaks or chatter out of the suspension. Maybe I am biased because what I took out was 27 year old bushings.

i prefer to just replace the front, the rear control arm bushings don't readily fail anyways and the difficulty in replacing the 2 rear control bushings versus the whole front is even more time consuming than redoing the whole front of the car.
slightly more flex in the rear is better anyways for additional grip, if you stiffen it up too much then the result isn't spectacular.

But if you don't have one of those, just drill all the way around the inner sleeve then pound it out with a hammer. Or preferably an air hammer., Yes, it's time consuming. Yes, it's annoying. But it does work.
