1997 Chevy Truck stupid truck

You replaced the 4 02 sensors why?

Not sure the relationship to the ABS.

Regardless the abs is probably false activating due to a sensor issue. Just not 02, more likley speed sensor.

The truck needs to have the codes pulled, then test driven with a partable diagnostic computer that can rea what the sensors are telling the computer.

My guess one or two of the front ones went south a little early this year.
