Suspension Chirp

[UMEXT]

Happens when moving forward over even slightly uneven pavement. Doesn't happen at all over serious irregularities, e.g. speed bumps. So far as I can tell, I have an OEM setup, though without any repair history, I don't know when (or if) the shocks were changed. I'm at about 126k miles. Seems to mostly come from the right rear.

Thoughts?

Many, many control arm bushings that you can spray with WD40 one at a time to localize. They do dry out. Upper and lower rear and front control arms, rear panhard bar, and especially the anti-sway bar mounting bushings.

Also lube the threaded hood height adjusters at the front corners of the hood. They are one of the most subtle possible sources of annoying squeaks in the vehicle.

Thanks, but other than the hood height adjusters, how do I identify any of them visually, and how do I access them without access to a lift? I can put my hand on ramps; would that be helpful?

I had a squeak for awhile after changing my whole suspension. All that needed to be done was turn the one of the hood adjusters out further. It was something so simple I don't know why I didn't check it earlier. With the hood completely shut, I could move it up and down slightly, but could not hear anything when I did this by hand. But I turned the adjuster out, the hood was much tighter, and the sound went away completely. Definitely something to check.

I had the same issues with my hood adjustors. Sounds silly but adjusting them fixed it.

Yes, but the noise is coming from the rear of the truck, not the hood. Now, can anyone help with my previous questions?

You should be able to reach any of the bushings with a can of WD40 and the spray straw that comes with it, without a lift and without ramps. Just involves laying flat on the ground. Do you need help identifying the control arms where the bushings live?

Items 7, 8, and 14.
