This weekend I replaced the aftermarket serpentine belt to get rid of an annoying "chirping" noise. I was pleasantly surprised when the new OEM belt not only solved the chirping sound, but it also seems to have solved the "clunking" sound of the a/c compressor coming on, and power steering is...
I am having intermittent hard steering issues also, but its on my 03' LC. I don't have a VGRS light on my dash, so I suspect I don't have VGRS on my particular model. I am curious, did you change the bushings and did it solve your steering problem?
