control arm bushing. Left side one is faulty. Replace one/both/allign
 

My right control arm bushing need replacement. Do I have to replace the one on the left side too or what? do suspension needs alignment after replacement? if yes, could it be done by the code scanner? How much do it need in matter of time and labour

if you are just replacing the Control Arms...you dont need to re-allign.......

if you are taking off the Tie Rods.then you need allignment.....and no,it cannot be done by a code scanner ...you have go to an alignment shop.

Just need to replace the upper bushing. I don't think you need to take off tie rods. Thanks pnoyako85

Do both sides.

This, replace parts in pairs almost 100% of the time.

Thanks DTman. Thanks Brit6
