I was just curious what control arm's everyone is running and why. Do you like them? Do you wish you would have went with a different brand?
I think the fact that you are running a locker too has to factor into the equation. The spherical ends don't have any give and when taking turns, the tires have nowhere to go since they are trying to spin at the same speeds. Where the LCA's tightened with vehicle weight on them? That might cause some squeaking too..I run these arms, and although they made a world of difference, I would be more than happy to switch to something MUCH quieter. I've done a million things to stop these from squeaking to no avail. With my locker paired up with these huge tires, whenever I make slow, tight turns, the wheels scrub a bit and make my control arms chirp like crazy. It makes me feel like my car's a creaky old battleship.
