Q: What should be inspected in accidents with potential steering column damage on Cadillac CTS?
A: A vehicle involved in an accident will need inspection when it suffers frame damage or major body or sheet metal damage or an impacted Steering Column or deployed supplemental inflatable restraint system may have a damaged or misaligned Steering Column. During the inspection of Steering Column bracket assembly capsules ensure they are tightly fitted into their respective slots while evaluating any loose bracket behavior when manually pushed or pulled. According to the method of bracket connection to jacket assembly there are two scenarios for repair : a bracket substitution when capsules are not properly seated and bracket uses bolts or only replace the jacket assembly when capsules are not properly seated and the bracket uses welding techniques. Jacket assembly replacement must occur when measurements reveal dimensions outside specifications from the lower edge of upper jacket to the specified point on the lower jacket. Check if the bearing and adapter assembly tabs have been damaged while inspecting the Steering Shaft for sheared plastic areas. When sheared plastic appears on the Steering Shaft require a new replacement shaft. A Steering Shaft runout test occurs with a dial indicator alongside the wheel rotation to check wether any framework damage has caused shaft bending or if the runout exceeds 0.0625 inches (1.60 mm).
Q: What should be inspected in accidents with potential steering column damage on Cadillac XLR?
A: Vehicles that encounter accidents with frame-related damages along with significant body or sheet metal destruction or Steering Column impacts or supplemental inflatables activating will potentially suffer from Steering Column malfunctions. The Steering Column bracket assembly should receive an inspection of its capsules through verification of proper bracket slot seating while also inspecting loose tolerance when hand test is applied. When examining the bracket-to-jacket assembly connection and capsule seat position ensure replacement of either the bracket alone or the complete jacket assembly based on these findings. The measurement of distance must be performed to test jacket assembly collapse; any jacket assembly requiring replacement should have dimensions that fall outside of specifications. Survey the bearing and adapter assembly for a broken tab while looking for sheared plastic on the Steering Shaft; if sheared plastic exists replace the Steering Shaft. A frame-related Steering Shaft bend requires dial indicator evaluation of the Steering Shaft lower end to measure runout during wheel rotation when the runout must stay below 1.60 mm (0.06 in).
Q: What should be inspected to determine if a steering column is damaged or misaligned after an accident on Cadillac Escalade?
A: Sustained frame damage together with major sheet metal deformations and collisions that strike the Steering Column or activate supplementary air bags will potentially cause damage to Steering Column alignment. Test each capsule in the Steering Column bracket assembly while inspecting its secure seating position in the slot system. Use hand activation to check for free movement or looseness. Replace the bracket when installed by bolts to the jacket assembly but change the entire jacket assembly if welding holds the bracket in place. Checking the lower edge of the upper jacket against a specific position on the lower jacket requires measurement to evaluate possible collapse. Stated specifications guide when to replace the jacket assembly. First detach the sir coil from the Steering Column before letting it drop freely while performing shaft rotation. A visual examination of the Steering Shaft should look for plastic shearing; replacement of the Steering Shaft becomes necessary when shearing occurs. A dial indicator measurement at the bottom of the Steering Shaft determines if frame damage exists by tracking the shaft runout during steering wheel rotation. The acceptable runout measurement is 0.0625 inches (1.60 mm).
