Yes, I needlesly replaced mine on my WJ, since they are both 4.7 liters they are similiar. Chrysler has a special tool for this but if you cannot get the tool your best bet for removal is probably the hammer and crescent wrench. With the pulley belt still on, get a large crescent wrench and grip the large fan clutch nut. You will need to hit it several times to knock it loose. The trick to finding out which way the nut needs to turn is to watch which way the fan spins while the engine is on. Hit the nut the same way the fan spun. My fan spins counter-clockwise, thus, the nut broke loose by me hitting it counter clockwise. Once you break the large nut loose, unthread it all the way and set it down in the fan shroud. I got this from another site and it worked for me.
