Before I take a "leap of faith" and spend approx $200 on new Lower Control Arms, is there a way to diagnose the bushing failure?
My 2011 EX with 99,000 miles has a pretty strong shimmy during hard braking at 60-65 mph. Most obvious when braking on freeway exit. I don't have any other symptoms - no clunking, no thumbing, no vibration, no shimmy while driving, just this strong shimmy while braking.
Lots of posts in the forum point to the lower control arm bushing with the suggested fix is to replace the entire lower control arm because it includes new bushing and ball joint.
My LCA Bushings seem stiffer/tighter than hell. With the car on jack stands and a floor jack slightly lifting the front suspension to take the weight off the LCA, I can't feel any movement in the bearing when prying with a crowbar.
Front brake rotors are an obvious place to look for shimmy while braking. Using a dial indicator, both rotors have .002" runout. Sure, .000" would be great, but would 2 thousandths runout cause a stong shimmy?
All other front suspension parts feel tight.
So I'm looking for any ideas to diagnose a possible lower control arm bushing failure?
