2004 Cadillac Escalade EXT Steering Shaft

You need to inspect the capsules on the Steering Column bracket assembly, inspect for jacket assembly collapse by measuring the distance from the lower edge of the upper jacket to a defined point on the lower jacket, remove the SIR coil from the steering column and allow the coil to hang freely before the shaft is rotated. You also should visually inspect the steering shaft for sheared-injected plastic, and inspect the steering shaft runout for any frame damage that could cause a bent steering shaft.

You need to disable the supplemental inflatable restraint (SIR) system, remove the inflator module and the horn switch, and make an alignment mark to note the relationship of the steering wheel to the steering shaft. You also need to remove the steering wheel nut and the steering wheel.
