Question 1

What should be inspected on those involved in accidents to determine if the steering column is damaged or misaligned on GMC Canyon?

Accepted Answer

Accidents that lead to frame damage along with major body damage and sheet metal damage together with impacts on the Steering Column or triggering of supplemental inflatable restraints systems typically result in misaligned steering columns. A complete inspection must verify that all capsules are correctly attached to their bracket slots before examining the system's loose conditions by manual pressure tests. The maintenance decision depends on bracket installation method; change only the bracket when it bolts to jacket assembly yet switch out jacket assembly when bracket welding exists. The distance between the lower edge of the upper jacket and defined point on the lower jacket must be measured for jacket assembly collapse evaluation. A replacement jacket assembly is necessary if measurements fall outside specified parameters. Pull out the inflatable restraint coil assembly from the Steering Column then let it dangle in free space to protect the coil assembly from harm before turning the shaft. A visual examination for sheared plastic in the Steering Shaft should be performed; replacement of the shaft is required in case sheared plastic is found. To detect incorrect Steering Shaft runout a dial indicator should be applied at the shaft bottom while wheel rotation with a maximum tolerance of 1.60 mm (0.06 inch).

Question 2

How Can a Collision Affect the Steering Column and What Inspections Are Necessary on GMC Envoy?

Accepted Answer

Damage to a vehicle frame along with major body or sheet metal damage and impact to the Steering Column or deployment of supplemental inflatable restraint systems can cause a misaligned Steering Column. All capsules on the Steering Column bracket assembly need to be checked to confirm their proper seat within bracket slots while also conducting a manual check for loose conditions. Brackets get swapped individually except when capsules stay loose and the bracket connects to the jacket structurally by bolt. The whole jacket assembly needs replacement under this scenario. The first step requires checking tab fractures on the bearing and adapter assembly followed by inspecting the Steering Shaft for sheared plastic material. If sheared plastic exists the Steering Shaft needs immediate replacement. Steering Shaft runout needs to be evaluated through a dial indicator check at the Steering Shaft bottom end when steering wheel rotation occurs. This evaluation must demonstrate less than 1.60 mm (0.06 in) runout.

Question 3

How to Inspect and Repair a Damaged or Misaligned Steering Column on GMC Jimmy?

Accepted Answer

Accidents that lead to frame degeneration or major body damage or sheet metal harm as well as Steering Column contact or activation of the supplemental inflatable restraint system may damage or misalign the Steering Column. Check the capsules on the Steering Column bracket assembly for secure bracket slot seating and inspect for looseness by manual hand pressure; replace the bracket through the jacket when bolted or replace the jacket when bracket welding is present. Verify jacket assembly collapse by checking the distance from upper to lower jacket edges at defined points; obtain a new jacket if measurements exceed specifications. Rotation of the shaft needs the inflatable restraint coil assembly to be removed from the Steering Column due to preventing coil assembly damage while hanging freely. The inspection of the Steering Shaft needs to be conducted visually to check for sheared injected plastic. Install a new Steering Shaft if sheared plastic is found. A dial indicator should be used to check the Steering Shaft runout at the bottom end during steering wheel rotation before continuing since runout should be 1.60 mm or less.
