4. Install the steering joint, and reconnect the steering
shaft and pinion shaft.
NOTE: Make sure the steering joint is connected as
follows:
a. Insert the upper end of the steering joint onto the
steering shaft (line up the bolt hole with the flat on
the shaft), and loosely install the upper joint bolt,
b. Slip the lower end of the steering joint onto the
pinion shaft (line up the bolt hole with the
groove around the shaft), and loosely install the
lower joint bolt.
Be sure that the lower joint bolt is securely in the
groove in the pinion shaft,
c. Pull on the steering joint to make sure that the
steering joint is fully seated. Then tighten the
joint bolts.
