I've had this squeak for a while and I decided to try and address it today so I started spraying my suspension points. I was rocking my truck back and forth to try and hear where it was coming from and my upper control arm uniball is wore out already. I mean I guess it is, i can grab my upper arm and move it up and down right at the uniball. This is on both sides, passenger side is worse though. I thought maybe the bolt came loose somehow but I can't even tighten them a little bit. I'm gonna have to contact Greg and see what he says, I've only had them for about year. At least now I know where the clunking has been coming from.
