Mack CX, CH: Steering
Affects Mack CX, CH · 2003 — about 343 vehicles.
The hazard
On certain vehicles, the bolts that mount the steering gear to the frame can fail due to bolt quality issues which cause variation in the torque-tension relationship for the joint. This results in an inconsistent clamp load, which can cause the bolt to be either over-stretched (at or above yield strength) or under-stretched when torqued to specification. Failure of two of the three bolts could result in loss of steering control. Correction: Dealers will replace the mounting bolts.
