my 97 blazer with a 2 inch superlift suspension lift has developed a loud clunk over bumps...i have deduced that is is because the upper control arm bushings are really worn out... My question is do they take special bushings since they are not factory control arms or should i be able to use the same ones i would use for the factory control arms?

 

They should be the same dimensions, but i would not install rubber bushings. Go with polyurethane.

 

alright well i guess im gonna pick up a set of factory sized ones and hope they fit.
