I own a 1991 4Runner 3.0 a/t. I've noticed for a while now that the front left area of the vehicle has been producing an odd chirping noise every time I hit a bump or travel on a rough road. It seems like it's coming from the front driver's side wheel well.

Any thoughts?

 

Maybe a bad or missing sway bar bushing, lower control arm bushing, plastic inner fender loose or missing a screw, bent metal dust cover on shock.

Try bouncing on the left front fender and see if you can reproduce the noise and then track it down.

 

Jack up each front wheel one at a time. Check for play in the wheel bearings, balljoints and steering parts.

Make sure its not just something simple

 

I haven't had time or daylight to check it out thoroughly yet, but the problem is really getting worse..
I have a hunch that it's the control arm bushings..the sway bar bushings look fine.
I can't really produce the noise with putting my weight on it.
