Jacket

Any vehicle involved in a collision that produces frame damage together with substantial body or sheet metal damage or hits to the Steering Column or has experienced a supplemental inflatable restraint deployment can exhibit misalignment or damage to its Steering Column. The inspection should evaluate steam capsule placement within bracket slots of the Steering Column bracket assembly while testing for loose connections by manually applying force to the capsules; bracket replacement should happen as a bolted attachment to the jacket assembly but the jacket assembly requires replacement when welded. Use a measurement tool to compare the lower edge of upper jacket distance to a marked lower jacket point as part of detecting jacket assembly collapse; a new jacket needs installation when measurements show incorrect dimensions. Rotate the shaft subsequent to removing the inflatable restraint coil assembly from the Steering Column while ensuring its free hanging position to avoid coil damage. A visual check of the Steering Shaft for sheared injected plastic should be performed; replacing the shaft with a new one is necessary if sheared plastic is detected. A dial indicator should be used at the Steering Shaft's lower end while the customer rotates the steering wheel to check runout until the measurement stays below 1.60 mm.

Accidents that damage the vehicle frame together with substantial body and sheet metal damage or impact to steering columns and supplemental inflatable restraint deployment require immediate inspection of the Steering Column. Check the Steering Column bracket assembly capsules for proper seating in the slots as well as any loose conditions by manually pushing or pulling the components. It is imperative to replace the bracket even if it is bolted to the jacket assembly yet a jacket assembly replacement is needed for weld-only constructions. A measurement of distance between the lower edge of the upper jacket and a specific point on the lower jacket needs to be performed to verify jacket assembly integrity. The assembly requires replacement if measurements fall outside suitable specifications. Detach the sir coil from the Steering Column then let it hang without any restraint to rotate the shaft. The inspection of the Steering Shaft must reveal sheared injected plastic which leads to replacement of the Steering Shaft. Measuring the Steering Shaft runout at the lower end requires a dial indicator to evaluate potential frame damage that would cause Steering Shaft bending; the allowed runout is limited to 1.60 mm (0.0625 inch).

Any vehicle with frame damage together with significant body sheet metal damage or impacted Steering Column or supplemental inflatable restraint system deployment may show damaged or misaligned Steering Column conditions. The inspection of Steering Column bracket capsules should verify complete seating within slots and ensure there are no loose conditions by manual push or pull tests; a new bracket requires installation if it bolts to the jacket yet a new jacket must be fitted if bracket connectivity is welded. To verify jacket assembly integrity measure the distance from the lower edge of the upper jacket to its definite point on the lower jacket while new jackets need installation if measurements deviate from specifications. Before rotating the shaft you should release the inflatable restraint coil assembly from the Steering Column to avoid damaging its components. Visual inspection of the Steering Shaft should be conducted for sheared plastic material; when this is detected the driver must install a new Steering Shaft. The lower end of the Steering Shaft requires dial indicator runout measurement during steering wheel rotation for any potential frame damage that could result in a bent Steering Shaft. The measured runout should stay under 1.60 mm.

Frame damage and major body or sheet metal damage alongside impact to the Steering Column or supplemental inflatable restraint system deployment will cause damage or misalignment to the Steering Column in involved vehicles. Check all capsules in the Steering Column bracket assembly for secure fitting within bracket slots while testing for loose mechanisms by manual hand pulls and pushes. The bracket requires replacement when bolted to the jacket assembly but requires replacement of the whole jacket assembly when welded to it. Check the jacket assembly dimensions from its lower edge to the specified point on its lower section; discard the assembly if measurements deviate from specifications. Before rotating the shaft remove the sir coil from the Steering Column to create free movement by the coil. It is necessary to visually check the Steering Shaft for injected plastic sheared parts because replacement of the Steering Shaft will be necessary if sheared parts are detected. Use a dial indicator on the Steering Shaft base while rotating the wheel to measure frame-induced shaft runout as it should be less than 1.60 mm (0.0625 inch).

Following a collision the new Steering Column contains one or two symmetrically arranged curve zones within its intermediate shaft (Fig. 1.22 and 1.23). The c1500 model has only a single curved area while other models have both sets of curved sections. Any inspection of convoluted areas following an air bag deployment must always be conducted. A straight edge should be applied against the intermediate shaft surface to check for straightness at different points along the convoluted region. The shaft needs replacement in case damage or bending occurs during the inspection process.

Accidents leading to frame damage combined with major body or sheet metal damage and both Steering Column impact and inflation of supplemental air bags will result in a misaligned or damaged Steering Column. Check all Steering Column bracket capsules to confirm their proper seat within bracket slots while also performing manual tests to check for loose conditions. Any loose capsules require replacement of the bracket whenever it uses bolts to connect to the jacket assembly or when it needs the complete jacket assembly replacement. A distance check should be performed from the lower edge of the upper jacket to a specific point on the lower jacket to detect jacket assembly collapse. Replace the jacket assembly if measurements fall outside of specifications. Take out the sir coil from the Steering Column until it forms a free hanging position before starting shaft rotation. Examine the Steering Shaft for damaged plastic material because replacement of the shaft becomes necessary if sheared plastic appears. When using a dial indicator at the lower end of the Steering Shaft to check the runout during steering wheel rotation you should ensure that the maximum allowable runout remains below 1.60 mm (0.0625 inch).

Arcs that arise from frame damage together with substantial body or sheet metal damage or Steering Column impacts or deployments of supplemental inflatable restraint systems could result in Steering Column misalignment. Inspect the Steering Column bracket capsule placement inside the brackets' holes while checking for possible loose components through manual tests; replace the bracket when bolted to the jacket and change the entire style if the brackets are welded to the jacket. Check jacket assembly collapse by measuring from the lower edge of the upper jacket to a defined point on the lower jacket and install a new jacket when the measurement results are outside specified ranges. Before rotating the shaft, let the coil assembly of the inflatable restraint hang loose in order to protect it from damage. Steering Shaft replacement is necessary in case sheared injected plastic is detected. The lower end of the Steering Shaft requires runout testing by a digital gauge during wheel rotation to ensure less than 1.60 mm error.

Replace the jacket assembly.
