with a plastic or rawhide mallet on the side oppo-
site the dry seal, while continuing to lubricate. If

screws at the bearing with the dry seal, to relieve
seal tension. Lubricate the U-joint until new
grease is seen at the seal, then tighten the cap-
screws to the correct torque specifications. If the
bearing will not take grease, replace the U-joint;
see Group 41 of the 108SD and 114SD Work-
shop Manual.

gritty, or burned, replace the U-joint.
