You can Select Your Vehicle to check if F5UZ-3V049-A fits your vehicle.

For the 2WD sub-models, the removal is done by first removing the spindle after which unscrewing of the snap ring from the lower ball joint which practically means that the lower ball joint is removed from the spindle first. Use a special C-frame assembly tool in combination with the correct receiving cup to press the lower ball joint out of the spindle; if you do not have a suitable cup, contact a dealership or machine shop. Like the lower ball joint, the tool setup is repeated on the upper balljoint and pressed out too. When fitting the upper balljoint, use the C-frame assembly and the receiver cup to tighten the screw until fully seated, to avoid the heating of the parts. Further ontinine with the same tolls as above, press the lower balljoint into the axle until it is flush then fit the lower balljoint snap ring. For 4WD models, the tasks include the elimination of the spindle, axleshaft, and its joint, further, they need to dismantle the cotter pin and nut of the tie-rod. Shunt the snap ring from the above ball joint and the screw of pinch bolt also the cotter pin was removed and the nut was loosened of the lower ball joint. Tap on the inside of the steering knuckle close to each balljoint to release the axle arm fro mthe car and unbolt the camber adjuster sleeve, put a mark on it so that it can easily be realigned. Lose the nut on the lower ball joint and mount the steering knuckle in a vise to extract the snap ring from the lower ball joint socket. Utilize the C-frame assembly tool for pressing out the lower balljoint; do the same for the upper one. All the dust and debris around and inside the steering knuckle balljoint bores must then be removed, then the lower balljoint slot must then be aligned with the knuckle and the C-frame assembly that is to be placed in is then inserted and set in its position with a slight press. Insert lower balljoint snap ring and again perform the procedure for upper balljoint. Replace the camber adjuster on its right place so that the arrow provides correct indications for camber correction. Position the steering knuckle as the camber adjuster was set without moving it; torque the lower ball joint with a new nut; add a cotter pin. Fit the tie-rod end to the knuckle, then nut the tie-rod and put a new cotter pin to keep the nut tight. Reverse the above removal process to complete the installation and take the front end alignment.

Check and adjust the front wheel bearings by raising the vehicle and positioning a jack stand under the I-beam axle beneath the coil spring. Have a helper grasp the lower edge of the tire and move the wheel assembly in and out while observing the upper spindle arm and the upper part of the axle jaw. A movement of 1/32 in. (0.8mm) or greater between the upper part of the axle jaw and the upper spindle arm indicates that the upper ball joint must be replaced. To remove and install, raise and support the vehicle safely with jack stands, then remove the spindle and the ball joint assembly. Take off the snap ring from the ball joint and use a ball joint removal tool to detach the ball joint from the spindle, avoiding any heating of the ball joint or axle. Installation follows the reverse of the removal procedure, ensuring the ball joint stud nut is torqued to 85-110 ft. lbs. for 1983-89 Ranger and Bronco II models.

For 1991 through 1993 2WD models, removal starts with the spindle followed by the elimination of the snap-ring from the lower ball joint with the lower ball joint being first. By using a special ball joint assembly tool with the appropriate receiving cup one can force the lower ball joint out of the spindle; if this is not possible, one should consult a dealer or a machine shop. Do the same for the upper ball joint and secure it with the same tools used putting it into the axle without heating of the components. This is done as follows: Mount the lower balljoint as described above and tighten it with the snap-ring; later carry out a front-end alignment test. For four-wheel models, the spindle and shaft assembly needs to be removed of which the tie-rod and upper ball joint need to be detached. After the camber adjuster sleeve is out, one has to take out the lower balljoint using a vise and a tool to press it out. Very carefully scrape the channel in the steering knuckle bores before fitting the new lower balljoint which has to be straight and seating it into properly. Proceed with the upper balljoint with due regard for the camber adjuster and tighten the steering knuckle with a new nut and a cotter pin. Last of all, install the tie-rod end and examine the front-end geometry. As for the models manufactured after 1995, the balljoints both on the upper and lower control arms are non- serviceable; replace the control arm if it is damaged. The lower ball joint is interference fit in the 2005 model, meaning that it has to be pressed out using a removal tool after removing the spindle /knuckle and snapping off the snap-ring, and then it has to be pressed in the same manner.

Assemble the balljoint press and the appropriate adapters over the new balljoint, turn the forcing screw on the clamp until the balljoint is seated, and install the snap-ring. Always install the lower balljoint first. Repeat the procedure on the upper balljoint and install the snap-ring.

Remove the inner and outer bearing cups from the rotor with a bearing cup puller.

Remove the spindle and the ball joint assembly from the vehicle.

2U2Z-3V049-A is the lower ball joint and XC2Z-3V050-AA is the upper.
