I gotta change these things out. They’re bad. I can wiggle them around with my hand no effort. I changed the lower arms and things were an inch off of alignment.

I was going to order a poly set so I wouldn’t have to press the old sleeves out. Just leave the metal sleeves in and clean the rubber out. Has anyone installed the poly bushings? I’m assuming that I won’t need to press the sleeves out Correct? Trying to make this Job as easy as possible for me

It's going to be a lot easier to scrub out the old rubber if you press the sleeves out...but seems like it's possible to install without pressing them out.

I put poly in so I'd never have to do it again. It's made the ride a little more firm. I'm thinking about swapping the arms back to rubber but leaving the poly in the axle bushes.

I had my garage do it and they pushed / destroyed the old sleeves out, ordered some new cheap *** bushes and used the sleeves from those.

Which manufacturer makes these in polyurethane? I like nolathane cause they were low price for the sway bar bushings but they dont carry these ones that go mounted on the axle.

Superpro - they make the best poly bushes. Minimal increase in NVH and no squeaking!

If you're not lifted, just get replacement arms with bushings already in them for same or less $.

Cool I already had ordered some rubber ones from crown automotive we'll see how long they last since control arms are polyurethane from core4x4. I need to repair these because I have death wobble due to caster being off and dont want to adjust it until everything is tight.

I agree that Superpro makes some of the best poly bushings out there, I would not recommend them in this situation if you want much flex out of the them. Poly does not flex much at all and when you try to get it to flex much it will start to bind. So would not recommend if you do any offroad, but should be fine on a daily.

I've had Superpro bushes in for 80,000 miles and they've only just worn out. But those IRO ones are cool! Are they stiff like Superpro or are they more soft like rubber?

Agree that superpro won't give you flex but why would you want flex in your upper arms bushes? Actually I guess they're pretty central on the vehicle so axle articulation means that the arms want to twist slightly.


I actually did what I was thinking about back in January and left poly in the axle bush mount and rubber in the arms.

Overall drive is much nicer now!

I ordered those from Iron rock since the rubber ones flex too much and I believe might be cause for death wobble. They cost the same as superprousa, heavier duty, and easier to service than having to press again. Thanks
