I have this annoying squeak that started on my left rear suspension - it SOUNDS like it's coming from where the spring and isolator meet. Can the isolator squeak?

I can basically just touch the car with two fingers and it will squeak, if that helps. And it squeaks constantly while driving, not just a squeak when I hit bumps.

 

I can't say for sure what's causing it, but I had a squeak that was coming from the right rear on my car. I just replaced my shocks and springs and in the process, obviously had to reposition the insolator on the new spring. Not sure if it was the insolator, but the sqeak is gone.

 

I can just about promise you (without seeing the car in person-that is) That the squeak is coming for the upper shock mount bushings- pull them out and grease 'em.
I just had this happen to me with the last set of Koni's I installed about a year ago- just pulled them down last week and re greased them. Squeak is gone. I first was thinking it was the spare tire squeaking in its holding area, but that wasn't the problem.

 

Awesome, I'll try greasing the shock bushings.

 

Yes! That was it. Thanks guys.
