Rear suspension creak

[Randy]

So my passenger rear suspension started making a creaking sound a few weeks ago and I don't know what it is. It only happens when the rear end squats due to acceleration or bumps.

Try to pinpoint the problem one diagnosis at a time. I would say check your panhard bar. If you have an aftermarket adjustable one sometimes the adjusting nut/s come loose. Gl

Other than springs, my entire suspension is stock.

Try to recreate the problem and hone in where you hear noise

Control arms? The bushings start to deteriorate over time

The bushings in the control arms and in the PHB will deteriorate faster if the car was lowered without loosening those bolts first and retorquing at the new lower ride height.

My guess is LCA. Its a good reason to start throwing upgrades at it!

Go out and push down on the rear passenger side and listen for the creaking. You may be able to get someone to help you find the location that way.
But sounds like a bushing has gone somewhere. If it's a lca and you want a cheap stock one, let me know; i have plenty of them.

If you're using lowering springs and still using the stock shocks, your shocks are probably worn out. The stock shocks don't last a real long time with lowering springs.

When my LCA's went, I found pushing up and down didn't make the sound, but rocking the car front and back did.

Thanks guys, I knew I would wear out the shocks but didn't know it would effect the phb and LCAs. I'll try moving the car and find the sound later this week!
