Can someone please help me. I've got the addco sway bars, front and rear. The only problem is the rear end link bushings aren't biug enough, so everytime i hit a bump they make the squeakest noise possible. Can anyone recommend what brand and size bushing I should use to fix this problem?

 

After a couple months I ditched the Addco end links and went back to stock ones with poly bushings.The stocks end links have that bearing which gives it better manipulation/range of motion.
If you want to keep the Addco end links, I know that Autozone usually has a good supply of bushings (Energy Suspensions and Addco) and if they arent stocked can be ordered in a day.
I also lube all my poly bushings with marine grade moly lube which does the trick for squeaks.

 

There is a ton of information on the Addco bars and endlinks ... do a search.
