So about a year ago, I changed my ring and pinion from 2.56 to 3.08. My abs light comes on ever since. I drove a different car last winter and have ingored it all summer. But now with winter coming I've decided to address this and get the abs fixed. Code 28. Seems its not happy that it thinks the back tires are spinning faster than the front. Apparently, the shop that did the gear swap neglected to install a 3.08 ABS reluctor ring, part # 26018943. Where can I find one?
