Bank 1 & 2, sensor 1 & 2????

I know I've posted about this today already but I really need to get this figured out. I need 2 O2 sensors, bank1 sensor one and bank 2 sensor 2. I'm pretty sure bank 1 is upstream and 2 downstream but am having trouble confirming front and rear? Can anyone clarify?

Oh I didn't realize you had the 4.0. In that case:

Bank 1 Sensor 1: 1/1
Bank 1 Sensor 2: 1/2
Bank 2 Sensor 1: 2/1
Bank 2 Sensor 2: 2/2

Chris, thanks again. From the description in your link I believe the 1/1 is the front upstream and the 2/2 is the rear downstream.

Unless you've done an engine swap...

6cyl A.K.A. Inline 6 is 4.0L in all WJ's.
8cyl A.K.A. V8 is 4.7L in all WJ's.

Those are the only two engine sizes offered for WJ's from the factory. They offer two versions of the 4.7 but ultimately, it's still a 4.7.
