Steering Column

The Steering Column from vehicles suffering accidents that produce either frame damage or substantial body damage, sheet metal impact or Steering Column contact or supplemental inflatable restraint deployment experiences misalignment or damage to its structure. Start the inspection by pushing on each Steering Column bracket assembly capsule while making sure they stay firmly locked in their bracket slots and demonstrate no loose behavior. When the bracket attaches to a jacket assembly through bolting operate the bracket replacement independently from the entire jacket assembly replacement process unless the bracket is welded to the jacket assembly. A measurement of the lower upper jacket edge to a specific lower jacket point must be conducted for jacket assembly collapse detection. Replace the entire jacket assembly when measurements show out-of-specification results. Take away the inflatable restraint coil assembly from the Steering Column before shaft rotation to ensurecoil assembly protection from harm. The inspection of the Steering Shaft for sheared injected plastic requires a new Steering Shaft when detected. Examine the frame for damage along with using a dial indicator to check the Steering Shaft runout at its bottom while rotating the wheel since the maximum acceptable deviation should be 1.60 mm (0.06 in).

The runout must not exceed 1.60 mm (0.06 in).

Look for sheared injected plastic.
