Spray some compatible lube on the bushings (there are two on each side of the car). That will make the squeak go away for a while.
Replacing front control arms isn't hard - I did it by myself in my garage - but you need big wrenches (to be safe, get every size from 18 to 22mm). I went with the Steeda control arms.
What is the weight of the Steeda arms compared to factory? Any reduction?
