• Q: How to replace the lower intermediate steering shaft (with JL7) on 2009 Cadillac STS?

  A: The first step for replacing the lower intermediate Steering Shaft (with JL7) requires two actions: straighten the front wheels by turning the steering wheel and turn the ignition on when the engine is off. Once the Steering Column gets removed you should tape the upper intermediate Steering Shaft to its actuator boot to stop them from drifting apart. Prior to detachment, remove the lower intermediate Steering Shaft bolt to separate the lower intermediate Steering Shaft from the steering gear. Climb to the passenger compartment to pull out all three Steering Shaft components together through the opening then detach the intermediate Steering Shaft bolt. Use the tape to keep the upper intermediate Steering Shaft secure while carefully separating the lower intermediate Steering Shaft from the center intermediate Steering Shaft using lubrication when needed. Install the lower intermediate Steering Shaft to the center intermediate Steering Shaft and bolt in the intermediate Steering Shaft bolt to 30 nm (22 lb ft). Models equipped with jl7 need the intermediate Steering Shaft seal to face in a specific direction to prevent unwanted noise and resistance during operation. The tenets of correct installation demand the entire Steering Shaft seal lip remains visible without any front or back folds or wrinkles. The repair team needs to assemble the lower, intermediate, and upper steering shafts through the passenger compartment and verify correct seal placement on the engine compartment side. Fasten the lower intermediate Steering Shaft to the steering gear through its matching interface then install and tighten the lower intermediate Steering Shaft bolt to 50 nm (37 lb ft). After removing tape from the upper intermediate Steering Shaft with boot you should install the Steering Column. Conduct the diagnostic system check as the last step.
