squeaks...
If it's from the rear, I agree that you could take a look at the top and bottom of the coils to see if dirt and dust is causing the squeak as they twist when you compress em.

If it's from the front, could it be your hood latch? Thats been known to squeak..

Good Luck.

I have the Ranchos and really liked the ability to soften up the fronts when I cranked my torsion bars up a few inches. I think it made a bit of a difference.
