I replaced the CV shafts yesterday... which was quite an experience in itself because the support bearing refused to come out of its bracket. anyways, i got it all back together and when i go and start the car now, the ABS light comes on and stay's on. any ideas on how to fix that?

 

Smells like the new CV installation...
- sensors cannot pic up signal. (? adjustment, dirt, wrong parts)
- ABS cannot get the signal (? broken wires, connectors)

 

check to make sure your replacement axle has the tone ring on it, looks like a gear
also you may have inadvertently damage the sensor when you pulled the axle.
