Start with the front wheel bearings check and rectification, lift the vehicle and placed the jack stand at the I-beam axle below the coil spring. There should be a helper to hold the lower edge of the tire and rotate the wheel assembly to and fro as you study the lower spindle arm and the lower part of the axle jaw; the movement should be about 1/32 in. Any wear of .080 or more is to be supplemented with a lower ball joint replacement. For upper ball joints use the following techniques on the upper spindle arm and the upper part of the axle jaw. For 1983-89 models, to make this operation the vehicle is raised on jack stands; the wheel and tire assembly; caliper; hub locks; wheel bearings; lock nuts are removed. Go on and take out hub and rotor, outer wheel bearing cone, and grease seal, the seal must be dumped out and placed back in after the assembling. After that, it is necessary to demount the inner wheel bearing and the bearing cups, and also to separate the spindle from the steering knuckle gently tapping it with a plastic or rawhide hammer. To the left, stripping required the removal of the shaft and joint assembly, while on the right, the keystone clamp was thrown away and the assembly was slid off from the stub shaft. The spindle should be clamped in a vise; the oil seal and the needle bearing should be removed, and, if needed, to remove the seal, it should be driven off the shaft. Remove the tie rod and ball joints and swing on the spindle hitting the studs to release the same. Pull out the camber adjuster sleeve followed by the lower ball joint nut, then use the C-frame and forcing screw to take out the lower ball joint, do the same to the upper ball joint. For installation, the lower ball joint needs to be inserted into the knuckle directly in which the use of C-frame and forcing screw will snug fit the ball joint followed by installation of snap ring. Fit in the upper ball joint in the same manner Afterwards fit in the knuckle to the axle arm making sure that the camber adjuster is in the proper place. Thread the specified torque sequence for securing the spindle, it is very important to align the bearing bores while making sure that it is clean. Insert the bearing into the bore and then fit the grease seal and if used replace the shaft seal with a new one. On the right side the rubber boot and keystone clamps to be fixed and the correct alignment of these parts has to be ensured at the time of fixing. Last but not the least, slide the shaft and joint assembly through the knuckle and then fit the splash shield and the spindle and then only tight the spindle nuts are to be tightened. Insert the bearing cups into the rotor, fill the spaces in the bearings with lubricant and the last step would be to fit the rotor onto its outer wheel bearing and the locking pieces.
