We have a 1997 Chevy Suburban, 4WD. Occasionally, when turning right (usually from a dead stop) there is a distinct "clunk" sound that comes from below the drivers side floorboard (with an equally distinct "clunk" feel in the floorboard). I used to have a Nissan Maxima that had some bad control arm bushings, and it feels pretty similar to the Maxima when I'd go over bumps and the control arm would bang around in the stiff bushings. Recently there's been a similar (but different) sound that happens when turning left - especially if it's a hard left.
I'm pretty sure this is the part that's causing at least one of those noises, and I looked on AutoZone's website/repair guides, but I couldn't find something definitive.
What is this part called?
(Up close - the bushing is pretty much gone)
