X2. My brake light didn't come on and mine didn't have ABS but when my speedo started bouncing everywhere, it was the speed sensor on the rear diff that fixed it.

05's have a single sensor at the top of the rear diff.
06's have sensors at each wheel.

speed sensor located on top of the rear diff, or the harness leading up to it. both available at decent price from dealer, both possible to install yourself.

Ok I found a sensor I'm hoping it s the right one on top of my rear differential I also notched when I put it in gear the jeep makes a loud bang sound I changed the transmission mount but I see behind on top of the rear diff is what looks like a bushing moving around and Leto g the diff jump up and down here's a video

Check the rear tri-link, there is a ball joint that attaches that part to the rear diff that goes bad, plus there are two bushings on the front part of the tri-link. Buy a good one, the cheaper ones you'll find will not last long

Ok so I changed the sensor however the cel is still on and now the code is p1794

Did you check the wiring to the sensor? Sounds like something is shorting out along the way, to me.
