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.
Replace the jacket assembly if the measured dimensions are not within specifications.

Visually inspect the steering shaft for sheared injected plastic (1). If the steering shaft shows sheared plastic (1), replace the steering shaft.

Any frame damage that could cause a bent steering shaft must have the steering shaft runout checked. Using a dial indicator at the lower end of
the steering shaft, rotate the steering wheel. The runout must not exceed 1.60 mm (0.06 in).
