position.
2. Turn ignition off (AIR BAGS CAN BE DEPLOYED IF CAR IGNITION IS LEFT ON).
3. Unbolt stock steering shaft from the steering column, and rack and pinion. Push the
steering shaft up toward the firewall until the lower steering coupler comes off the rack
and pinion. If the shaft is corroded and won’t come free, remove the rack and pinion
assembly from the frame and then remove shaft.

New Shaft Installation:
4. The new shaft requires some assembly and adjustment according to the column to rack
and pinion relationship.
5. Install the lower U-joint # 8050230 on the rack and pinion. Position the u-joint so the bolt
hole lines up with the notch on the pinion shaft. Install the ¾” DD end of the shaft into the
upper yoke of this U-Joint. The splined end of the shaft will point up towards the column.
6. Install column insert into steering column tube, line up the hole on the insert with the
column tube’s holes and install the column bolt.
7. Install the upper U-joint # 8050440 onto the shaft, so that the U-joints are 90˚ out of
phase. (see diagram below) to prevent binding. This is called “MIS-PHASING”.
8. Now install the upper U-joint onto the column insert and install U-Joint.
9. The column tube is adjustable and may have to be pulled down or pushed up in order to
line up the lower U-joint bolt hole and the pinion notch, install U-joint pinch bolt and lock
washer.
10. Tighten all U-joint pinch bolts.
