Hey all,

Mine has been doing that to I have a 99 GPGT and out of the blue my ABS & TC off light started coming on. I went to a mechanic buddy of mine and he let me use the scanner the shop had and the scanner told me it was a bad wheel speed sensor which is in the hub assembly. I guess that's what I get for buying cheap parts...(if you can call 80 bucks each cheap for a hub assembly).
