When you buy bushings, the urathane is already encased in sleeves

Ok. I was already aiming at changing the ball joints... and pretty much everything XD It'* going to be quite a rejunevating adventure. I'll still probably just take out the control arms and have it done. We have mechanics where I work and I happen to play paintball with the boss. I checked, they are equipped to do the job. That'* how it'* going to be!

But still, thanks for all the answers, I understand a whole lot more how it'* made now.
