are energy suspension bushing kits that good.. How much will it help my 89 bird and can I install them myself?

 

Yes! The ES parts are that good. The poly bushings will make a big difference. But the trade off is that you will get more road noise in the car.

Without the proper tools to press the bushings in the control arms it might be rather difficult for you.

 

The Energy stuff works great. Not easy to install everything though. The sway bar end links and bushings are easiest. If you want to replace the LCA bushings it would be easier (and not terribly more expensive) to replace the LCA with a stronger unit. The bushings on the front control arms are a major project. At a shop, with an experienced mechanic, it took almost one hour per side to replace the two bushings and ball joint. Torches, hammers, chisels, not a pretty site.

 

Ill vouch for the control arm bushings and ball joints being a pain in the ***. Spent the better part of a day removing the control arms and getting the original (read: 20+ years old now) balljoints out. Busted the spindle clear through them. I had the control arm bushings installed at a shop, cost me about $40, and it took a half hour. Now all i need is some paint and the balljoint pressed in and im good to go.

Yeah, the point of this was that ES parts are good, but if you do anything but the sway bars, its a good deal of work
