Always keep ball nut assembly in a horizontal po-

Inspection and Repair
Make necessary correction or parts replacement if wear,
damage or any other abnormal conditions are found
through inspection.
Visual Checks
Inspect the following parts for wear, damage or other ab-
normal conditions.
• Bearing
• Sector shaft
• Ball nut and worm shaft
Ball Nut Rotation
Hold the worm shaft vertically and see if the ball nut low-
ers with turning motion smoothly. If lowering of the ball
nut with its own weight is unsmooth, check the worm
shaft for bending and ball-groove for burrs, dents and
presence of foreign matter.
Notice:
When making a test on the ball nut assembly, exercise
care so as not to strike ball nut against end of worm
shaft, or damage to the ball tubes will result.
If any of the parts in the ball nut and worm shaft assem-
bly is found to be defective, the entire parts should be re-
placed using a new worm shaft assembly.
As these parts are of selective combination and are
sealed to prohibit disassembly, the faulty parts should
not be replaced individually.
