We just bought a used STS4. So far, I'm pretty happy with the car, but we have noticed a type of "grinding" that I cannot determine whether it is a problem or just a characteristic of the AWD system.
When turning and/or accelerating at low speeds (traffic, parking log, driveway, etc.) one gets the sensation of grinding or vibration from the front end. I have particularly noticed it through my left foot when it is resting on the foot rest, but it is detectable otherwise too. It is accompanied by a subtle grinding noise also from the front end. It's not the power steering pump because I checked that, and it will do it even when not turning but rather just accelerating from very slow or a dead stop.
I have an STS-V as well and it does not do this, but that is a completely different set up than the STS4.
Do any of you STS4 owners notice something similar? Before I take it to be serviced, I want to see if this is simply characteristic of all wheel drive or whether it is an actual problem.
