Old fart with a wrench
Okay, this jeep (WJ) has the np247 transfer case which is constant 4wd just like the older ZJs with the np249 t/case. As far as lifts are concerned, it's no different than other jeeps that use the same platform,ie;double solid axles and coil springs. the 2005 and newer ones (WK,WK2) use independent front suspension and don't take as easily to lifts.

In some areas AWD is even banned on beaches. I think this was South Carolina or Georgia. Really the high range is intended for on-road use only.
Have you checked the fuel pressure? Replaced spark plugs?

Test the battery for voltage ON THE POSTS, not the cables. Then check the voltage at the red wire on the PDC (Power Distribution Center, box under the hood)to ground on the body. I'm thinking the battery cable clamps are the problem. Look for green corrosion where the wires enter the molded terminals.
Update ~update~
The weather broke and 40s isn't to bad. After taking both batteries to the local autoparts. The optima is 25% of predictable cycles of use and to my surprise the wet cell battery is at 75% predictable cycles of use.
The positive battery terminal appeared to be slightly larger then the positive battery post. Bad (loose) connection and close to zero weather. Not to mention a defective Sears battery charger. I didn't consider replacing the positive with a aftermarket connector because of the TWO power cables needed one for the starter and one to power distribution box or fuze box.
I removed the nut on the positive terminal opend of the soft lead up a bit with a pair of Stout needle nose pliers. The I took a cut a piece of Romex wire 3 inches made a open endded loop. Like a upside down (U). The bend the (U) a second time at the legs at 90°. Place the hump of the upside down (U) up through the eye of the terminal, then push on to battery positive battery post. As pictured.

And around the the bottom between battery and the terminal.

Not in high range. The NP247 doesn't use a mechanical differential and isn't locked like a true 4WD case. It is a clutch-based differential that has pressure applied by a little internal pump, that engages the front axle when it thinks it's necessary. In low range that little clutch is locked in place so you get actual 4WD.
In some areas AWD is even banned on beaches. I think this was South Carolina or Georgia. Really the high range is intended for on-road use only

[B]thank you dave1123 battery termals clean. No over charging alternator. Just got back from having both batteries tested. Wet cell 100% optima 25%. I haven't gotten a chance to install either but will tomorrow. I greatly appreciate your response. Thank you so much. I hope my 20 year old charger is faulty. My jeep is one of two running so ol'silver back is vital to my current survival. Being a guy that has made more then his fair share of mistakes child support and bankruptcy your response means a great deal to me thank you.

Miswired electric fan
Howdy: My 96 XJ has two fans, one belt driven and one electric, like it's supposed to. But for whatever reason, the electric fan is jump wired to one blade on a 15 amp fuse in the fusebox instead of more formal wiring, and I think that may be causing some codes I'm getting, like running too cool (cuz the fan is always on). How can I find the place the electric fan should be connected so I can hook it up right and have it under computer control?

I'm not sure where it should connect at normally, but someone may be able to help you there. But I will say you should replace the thermostat with a Mopar OEM 195 thermostat to correct your under cooling condition.

The fan won't affect how cool it runs, because if the thermostat is doing its job the coolant is not flowing into the radiator until the thermostat opens. I would guess someone hardwired that fan because it wasn't kicking on as it was suppose to, or they just wanted it to run all the time versus at a higher temperature.

ZJ Hesitation in Acceleration
I have a 98 Jeep Grand Cherokee (ZJ) 4.0l and I've been experiencing some problems it's starts to buck and it starts around 3,000 rpms and when you let off or drive slower it stops. I've read on another forum that the problem was the O2 Sensor or either the fuel pump. Has anyone else here had the same problem?

98 grand rebuild
I'm rebuilding g a 98 grand cherokee and need to get the wiring right. I have connected everything in the proper place or so I thought. There are two bolts on the ignition coil. One that holds a ground wire and the other either holds nothing or a four wire brass connector. I need to know where this wire goes as mine is producing 4amps and probably should not be connected to a ground. If anyone can provide me with an image as to where these wires goes it would help greatly.
