I was wondering if there was anyone that could tell me if it is hard to change a Rear Wheel Bearing on a 93 Jeep grand cherokee 4.0L V6 i just purchased one for 300 Dollars and need to get this fixed Thank You

You will need to remove diff cover draining it so you can remove c clip that holds axle in differential. You brake assy needs to be removed. you may need to use a hammer slide puller to get axle to move. Then on that slide hammer an attachment that locks behind bearing may be used to pull bearing. The seal can be pried off first or may pop when bearing is pull hammered out. You should buy book like haynes to reference if you are going to attempt for first time,it is important not to turn differential while you do this job.LOL
