I ended up installing the front control arms in the same evening as the rears. Man what a difference these arms make! The Jeep drives so much better and quieter, and the squeeks are gone. When I go over railroad tracks it is now more of a "thump" sound than a full on rattling and a hard knock sound. One of the reason I picked the Metal Cloaks was because of some of their marketing literature indicating that had some of the least impact vibration that came through their arms versus the competitors. I would say the market literature was correct!
