I have an 07 with almost 117k miles. I am wondering how you tell if control arms are going bad. Car handles well, tracks perfectly straight, no strange clunks or noises. The arms themselves seem solid and you can't move them by hand. I have attached some photos of the upper arms on each side. Any feedback?

 

If the alignment and tire wear is good and if you aren't noticing nosies then they are good to continue on.

 

That last pic looks like the bushing is starting to tear. Even when the bushings began to go bad you won't be able to feel a real difference in ride. I removed mine at 100k and even though there were some cracks the bushings were still good. The balljoints on the bushing were worn out though but the alignment was still good and there were no noises. I would spray the wheel wells down real good at a self service car wash and take more pics to get a better ideal of their condition.

 

So you replaced yours at 100k? Did you notice a difference?

 

The car felt a lil tighter but I attributed that to the balljoint on the control arm rather than the bushings. Like I said the old bushings were still in good condition.
