The squeaky wheel ... er ... suspension gets the grease

I've developed a really annoying squeak in my driver's side rear suspension. I can't figure it out. It's pretty intermittent, but is loud when it happens.

I've been trying to troubleshoot this thing for nearly a week now. I started by simply jacking the car up, and rotating the coilover perches. That seemed to take care of it for a few days. Heck, I took an 800 mile road trip to Northern California, and never heard the squeak.

After returning to Portland, the squeak came back. I jacked the car up and removed the rear spring and shock. I took the mounts off and used "disc brake lube" (as recommended by the guy at Baxter's Auto Parts) to lubricate all of the bushings (top and bottom mounts on the coilovers). Reassembled, test drove, and the squeak is still there. Grrrr...

Next, I made sure the tops on the shocks were tight. I noticed the squeaking side wasn't at tight as the non-squeaking side, so once everything was snugged up, it was off for a test drive. And yet again, the damn thing squeaked.

Angered, I drove to work, listening to all the squeaking. When I left work yesterday, I headed home and noticed no squeaking. Okay. I set off to run some errands that evening, and again, no squeaking. Whatever.

I'm wondering if it has something to do with the temperature outside. On my road trip, it was in the 70s. The squeak returned when it got cooler. Yesterday it was warmer. We'll have to see what today brings.

So far I've been lucky with my Yaris LB with 14,000+ miles.

I've had zero problems with mine, too. The squeak went away for about three days, but is now back. I'm beginning to think it's temperature sensative.
