Well I swapped out the control arms yesterday. I don't notice any dramatic difference in how it drives, but it feels a little tighter in the front end, and that annoying metallic sound when backing out and turning out of the driveway is gone, so it was definitely the wasted arms making noise in certain situations. I've also have/had some sort of clicking sound from the front when the suspension was moving when off road. I haven't had a chance to see if that is gone now too. All in all, considering how cheap and easy this was, I probably should have done it a long time ago.
