HELP: Groan when steering to the left and with rear passenger only Hello. I am the original of a 2002 A4 SOM Z28 with full external engine bolt-ons, completely-upgraded suspension, and the fully-optioned Midwest fabricated 9 inch rear. Recently, I had two passengers in my car including my Bro on the passenger side and my Wife on the rear passenger side. As the car would roll (with or without acceleration) and whenever I turned the steering wheel to the left, I would hear a deep groan come from the mid-underside of the car. This only happened whenever I had a rear passenger and whenever I turned the steering wheel to the left. What would be the cause of this groan? Thanks in advance for any info.

If you went with poly bushings it could just be them squawking when under load. Some folks use rubber in certain areas just to avoid the creaks and groans.
Other idea is side loading causing something like the torque arm or even a rear wheel to rub.
When you accelerate you load the rear. When you turn left you load the right side. I'd start looking at the right rear wheel and working in from there. If you don't find rub marks on anything then have someone jack the left front while you watch the joints and bushings for binding.
