Service Limits

BALL JOINTS AND CROSS AXIS BALL JOINTS (CABJ)

Item Limit
Noise The ball joint/ball joint assembly shall exhibit no squeak, grind, rattle, or other abnormal noise when oscillated or rotated. See Noise and Vibration.
Dust boot Visually inspect the dust boot for damage:
  • No crack exceeding 19 mm in length, and no crack with depth exceeding 30% of the local wall thickness.
  • No more than 25% abrasion of wall thickness at folded area.
  • No unusual permanent fold conditions allowed.
  • No unseating of the seal from the housing or inner collar.
  • No bond failures to bonded inserts.
Play No axial or radial free play greater than 1 mm (± 0.5 mm) when inspected/loaded by hand.
Breakaway torque 10 N.m (7.37 ft-lbs.)
BUSHINGS

Item Limit
Noise Bushings are designed to exhibit noise in the case of severe degradation. Rubber folds, non-detrimental cracks, and other non-detrimental damage is permitted. Generally, bushings should not be replaced unless there is a noise that exceeds the allowances listed below.
Rubber deformation Cracks are considered non-detrimental if they extend to less than 20% of the entire cross-sectional area of the part, where the relevant cross section is assumed to be the most likely/apparent progression path of the crack should it continue to grow and considering the cross-sectional area of the part, not any single length dimension.
For example, a crack extending around the entire circumference of the part (360 degrees) but only 19% of the axial thickness is acceptable (100% * 19% < 20%). A crack extending through the entire thickness of the part but only 19% around the circumference is also acceptable (100% * 19% < 20%).
Play 0 mm. Elastic play is allowed. Any additional play is not allowed. No contact with other component surfaces is allowed.
HALFSHAFTS

Item Limit
Noise See Noise and Vibration.
Dust boot See Ball Joints.
Lash No rotational lash of the inboard joint with respect to the outboard joint is allowed greater than 1.5 degrees (± 0.75 deg) when inspected/loaded by hand (excepting spline connections to the motor/hub/jackshaft/etc.). Levers or other tools are not permitted.
WHEEL BEARINGS

Item Limit
Noise See Noise and Vibration.
Play No angular free play greater than 1 deg (± 0.5 deg) is allowed when inspected/loaded by hand. Levers or other tools are not permitted.
