REAR DRIVING MECHANISM
SERVICE INFORMATION
GENERAL
• Perform the gear contact pattern and backlash inspection whenever you replace the bearings, gears or gear case. The
extension lines from the gear engagement surfaces should intersect at one point.
• Protect the gear case with a shop towel or soft jaws while holding it in vise. Do not clamp it too tight as it could damage
the gear case.
• When using the lock nut wrench, use a deflecting beam type torque wrench 20 inches long. The lock nut wrench
increases the torque wrench's leverage, so the torque wrench reading will be less than the torque actually applied to the
lock nut. The specification given is the actual torque applied to the lock nut, not the reading on the torque wrench. Do
not overtighten the lock nut. The specification later in the text gives both actual and indicated.
• Replace the ring and pinion gears as a set.
• For bearing replacement in the knuckle (page 16-7).
