Just dropped the car off at Honda this morning for timing belt, water pump and valve service. The car has 371,000km on it. They found that both the upper control arms are gone (original) and a lower ball joint as well. They want 0 CAN for the control arms installed (both) and 9 for the ball joint installed. Part cost is 5 for both the control arms and for the ball joint. I've done the brakes, shocked, rad, alternator and other tune-up stuff myself. How difficult are the control arms and a ball joint to DIY? Thanks, Scott
