For several months my car has had a fairly rough vibration while turning right, and only while accelerating. (only felt on highway on-ramps, really) Often my ABS/Traction control lights come on, seemingly out of nowhere. Last night I was driving home on the highway, and I noticed an unusual vibration while going straight. As I was pulling into my parking lot it started making a loud clunking noise. This loud noise persisted both while going straight and turning, but it seemed to fade when I let off the accelerator. I haven't driven it any faster than 10-15 mph since hearing this. Initially I was suspecting the CV axle, but today I jacked up the car and it feels like the bearing has a lot of play.
