00 JGC O2 Sensor Replacement

[a97ducati748]

Can anyone tell me how difficult the O2 sensor replacement is on a 2000 Jeep Grand Cherokee Laredo? I just purchased two Bosch universal O2 sensors (one for before the cat and one for after). I just want to know what i am getting myself into before I start.

PS. I also bout the special too to remove.

Thanks

JUST LIKE CHANGING A SPARK PLUG, DISCONNECT THE WIRES, UNSCREW THE SENSOR, ISERT NEW SENSOR, THERE IS ANTI SIEZE COMPOUND ON THE THREADS ( DO- NOT REMOVE ). SCREW NEW SENSOR IN BY HAND AS FAS AS YOU CAN. FINISH TIGHTENING WITH TOOL. HOOK WIRES UP & TIE UP AS FAR AWAY FROM MANIFOLD AND HEAT. DO-NOT SPRAY ANYTHING ON THEM WHEN YOU REPLACE THEM. YOU CAN START JEEP AND WARM THEM UP IF YOU HAVE TROUBLE GETTING THEM LOOSE. NEVER HAD ANY TROUBLE. DON'T GET BURNT THOUGH REMOVE BAT. GROUND CABLE FIRST HOPE THIS HELPS QUESTIONS HOLLER HAVE SHEET IF INTERESTED. DALE

I just replaced the O2s in my 99GC with 4.0
Went to NAPA and bought 2 sensors went to install them found I had 4 sensors (Calif.) not 2(federal) truck was a factory order and I don't live in Calif.
2 O2s high up before 2 "mini" cats. and 2 after.
The install was easy xcept the rear lower sensor was to tight to exhaust y to get socket on. Had to cut wire and use a box wrench.
