Re: Wheel Bearing & ABS Light

I've changed a few of those bearings and only had the one give me trouble. I think the OEM pulse generator just has a longer pulse width than the newer replacements. That's not because the bearings are cheaper today, I think its just a very close tolerance spec and maybe some computers are pickier than others. This is one of those parts I never order online because of the possibility of having to exchange it as soon as its installed. Shipping would be nasty on this hub!

I had a GM service guy tell me to change both bearings a the same time to avoid the problem, but really, who can afford that?
