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 Nm
BUSHING SPECIFICATION

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.
HALFSHAFT SPECIFICATION

Item Limit
Noise See Noise And Vibration  .
Dust boot See BALL JOINTS AND CROSS AXIS BALL JOINTS (CABJ)  .
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 BEARING SPECIFICATION

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.
