Assuming you might have meant a 97 Wrangler with the 4.0 then look at the drums/rotors for an electrical connection for speed sensors. No sensors, no ABS.

The ABS system resides on a small tray on the driver's side behind the front fenderwell, with brake lines leading to it from the master brake cylinder. If that tray is empty, no ABS. The tray I am describing is big enough to look like a battery tray but it's really meant to hold the ABS system.

Find an empty piece of road. Jump on the brakes. If you lock your wheels, you don't have ABS.

you're mistakenly assuming all TJ's can lock up their brakes to begin with :mooning:

I wasn't able to lock my tires on dry pavement until I installed the Vanco Big Brake kit. Jeep wouldn't stop worth a damn in stock form.

This. It's that simple to look
