If you are still rolling on OEM bushings then yes replace them all, CA, strut and RR. If OEM the end links are probably bent. (If you don't mind me asking) Why coil overs?. The sway bar(s) paticulary the front, are not a simple remove/replace; the motor has to come off the mounts, (tranny mount has to be backed off) and suspended because the sub-frame has to be lowered and it ain't no picnic at that. To hang a motor things have to come off or risk tearing them up. While the motor is free you might think about those mounts as well, like the bushings those factory pieces suck. Most don't do anything with them because you have to hang the motor but you are going to have it free anyway sooo.... There are 3 choices; urethane is a big improvement, billet is strictly hard core and delrin falls in between (I'm using delrin). For the transmission mount I can tell you how to beef that up for @15 bucks or you can leave it go or you can drop 2 bills on a fancy new store bought unit that gets you powder coating and not a hell of a lot more for the money.The rear is (technically) serviceable in frame, in reality not so much especially with new bushings; the back of the strap is a tab the front a single stud, the front is the problem, there is all but zero room to get one hand in there, next to impossibal to manuver and new bushings generally need some force to get the keeper close enough to catch threads on the stud, if you up the size of the rear bar the situation only gets worse. Do yourself a favor; drop the sub-frame and call it a day, while you have it apart change those bushings as well. Some say sways can be done without taking the world apart; I'd wager they have never tried it. The rear maybe if you have tiny, T-Rex style hands but the front has to come apart a lot. That said it is totally worth doing.So if I go with the coilover route, I'd definitely do the upper strut mount bushings. Would be wise to do the control arm bushings at this time as well? I've definitely heard the differential mount being a common upgrade. I was thinking about sway bars too.
Are you saying you had the MaverickManCarbon coilovers then? And the end links that came with them were no good?
