If you have a GMT800 body style truck/SUV you probably know about the intermediate steering shaft making the horrible knocking/popping when turning and going over bumps.
Here's a little walkthrough to help you replace that steering shaft with the new designed, non-greased, steering shaft. Part number 19153614
• I-shaft P/N 19153614 has been designed to replace previous designed dampened and non-dampened I-shafts. The physical difference in the yoke size will accommodate all vehicles listed in this bulletin.
• Due to the design of the new I-shaft, it is not possible to lubricate/grease the I-shaft.
Set the front wheels in the straight ahead position.
Notice: On the 2002 and later model year vehicles, the steering column LOCK was removed from the steering column. It is critical that the J 42640 - Steering column Anti-Rotation Pin is used when servicing steering columns on 2002 and later model year vehicles. Failure to use the J 42640 may result in damage to the SIR coil.
Set the steering wheel in the LOCK position on 2001 and prior model year vehicles.
From under the hood, remove the lower bolt that connects the upper intermediate shaft to the steering gear coupling shaft.
Slide the shaft towards the dash in order to disengage the shaft from the steering gear coupling shaft.
For vehicles equipped with adjustable foot pedals, perform the following steps:
1. Reposition the carpet away from the accelerator pedal position (APP) sensor.
2. Remove the two nuts retaining the accelerator pedal to the bulkhead.
3. Reposition the accelerator pedal out of the way so the intermediate shaft can be removed.
From inside the vehicle, remove the upper bolt from the upper intermediate steering shaft (1) to the steering column connection.
Remove the upper intermediate steering shaft assembly.
1. From inside the vehicle, slide the shaft down and off the steering column.
2. From inside the vehicle, slide the upper intermediate shaft through the dash boot seal and remove the shaft from the vehicle.
Replace the upper intermediate shaft.
Install the upper intermediate steering shaft through the dash boot seal and slide the lower end into the steering gear coupling shaft.
Raise the upper end of the intermediate steering shaft and install into the steering column shaft.
Install the upper bolt and nut.
