if somethings not clear, ask, the book is for trained pros.
so works from there.

Hello there,
To replace the front ball joint on your jeep. You will be needing these instruments, Lug wrench Jack, Jack stands, Wheel chocks, Socket set, Wrench set, Needle-nosed pliers, Hub puller, Ball joint separator, Hammer, Ball joint press, Torque wrench, then, Please follow the steps below:
Loosen the lug nuts on your Cherokee's front tires, using the lug wrench. Jack up the front end of the vehicle and brace it with jack stands. Place wheel chocks behind the rear tires to prevent rolling. Back the lugs off the lug nuts, and remove both front tires from your Cherokee.
Remove the bolts behind the calipers. Lift the calipers off the hubs and set them on a support so they do not stretch the rubber lines.
Pull straight out on the brake rotor to remove it from the wheel studs.
Remove the cotter pin from the end of the axle shaft that extends through the hub. This is best done with a pair of needle-nosed pliers. Remove the drive nut from the axle shaft, and set it off to the side.
Remove the three bolts retaining the hub. These 12-point bolts are on the rear of the assembly.
Separate the hub assembly from the knuckle; a hub puller will make this easier.
Remove the cotter pins from the ball joints, using the needle-nosed pliers. You must detach the pins from both the upper and lower ball joints. Use a socket and ratchet to remove the nuts at the bottom of each ball joint.
Insert a ball joint separator between the knuckle and the ball joint. A hammer can be a big help to drive the separator into place and force the knuckle and ball joint apart.
Use a ball joint press to remove the joints. The ball joint press will force the upper and lower ball joints out. Follow the instructions included with your press.
Insert the new joints, using the ball joint press. You must reverse the motion of the press this time, pressing down on the upper joint and up on the lower joint. Be sure that the joints are completely in place within the knuckle.
Reinstall the steering knuckle onto the new ball joints, and thread the nuts onto the bottom of the joint. Check your manufacturer's specifications for the torque requirements for the nuts. Insert the cotter pins, and bend them down around the nut.
Reassemble the hub and axle around the knuckle. When replacing the three bolts, torque them to your manufacturer's specification.
Place the brake assembly back into position, both rotor and caliper. Replace the two bolts you removed on the caliper. Torque the bolts to your manufacturer's specification. Place the wheel back on the Cherokee, and tighten the lug nuts appropriately. With the wheel secured, lower the vehicle back to the ground.
Hope this was helpful to you. Goodluck Elect_Comp

It's called just as you saw it, rear upper ball joint. The parts guy may be trying to look it up through
the rear suspension diagram, my shop manual does not show it in the diagram either. But under
rear suspension components it's listed with pictures. Another reason they don't list it is becouse
it may be a dealer only item. Ask them to take another look or give the dealer a call, but it exists,
I swear. Hope this helps.

this is a a link to an example of the rear ball joint

... this bushing actually mounts in the rear hub carrier and connects to the upper control arm

Go to the auto parts store and buy a ball joint fork. You loosen the nut then put the fork between the ball joint. hit it with a hammer. be careful to not damage the boot. once the ball joint loosens up do the other side then remove the nuts.

if its like my 95. the only tool that would work was a large brass hammer. the 95 is pressed in. first check the auto parts stores for the correct ball joint puller. if that doesn't work get ready to start swingin. don't hit the fender.

first. i don't know why you would have ball joints in the rear end. it is not a steering axle. don't do it. your gona get hurt. take it in and let a machanic work on it. second you don't take the shocks or springs out to replace ball joints. just the wheel assembly comes off. and yes i believe there are alighnment adjustments for the rear. but i wouldn't do that at home myself. take it in.

you have a warped rotor which is causing ball joint.tie rod end.idler arm(if equipd) probs.bad rotor caused by sticking caliper which over heated and warped rotor.and also bad tire or wheel or both.put the wheel on a balancer and see if its bent or if tire has belt blister.replace rotor,caliper,wheel bearings and ball joint and any other loose or worn susp/steering gear.if you just replce rotor , going to happen again but worse damage.poss breaking pwr brake booster from vibration. gino R

The only parts you need are the ball joints, upper and lower, a total of 4, if you need all 4. As far as tools, you'll need wrenches, a removal and installer tool, the ball joints are pressed into the control arms, and a ball joint to steering knuckle seperator tool.Without those special tools, you will never get them changed, if you do it yourself.
