I replaced the gasket on my differential because of a leak and now my abs is acting up. I read the fsm and it seems to lead to the speed sensor not being seated properly. I went back over and made sure it was in all the way and still the problem persists. Is this part known to give problems after having been removed and reinstalled? If I have to replace it, do I need to use a special sealant? I've heard of some sensors being sensitive to different substances...Is this one of them? '91 4Runner V6
