LIC Motorsports in Novato, California, (a Subaru specialty shop) says the problem with control arm bushings is a design flaw starting in 2005 and continuing except for the later models of STi that got the ball joint suspension. They've had to replace a lot of them by now. My first set was replaced under extended warranty at 60K miles. The second set wore out and (of course) wore out the outer edges of the tires by 135K miles. I just had LIC replace them. The new ones are Whiteline ALK Comfort, made of polyurethane instead of rubber. LIC said they would produce more road noise, but I don't notice any difference in noise or comfort. Handling seems better and more controlled. Of course I got new tires and alignment at the same time.
