bearing rollers when joint is disconnected if tie wire
has been removed (Fig. 4A-5).
3. Attach a 1/2" drive adapter and socket to a
lb. in. torque wrench. Place socket over drive pinion
nut and turn pinion two or three revolutions to ensure
free movement. Then take a torque reading while
rotating pinion to measure bearing preload (Fig.
4A-6). Record reading.
NOTE: Additional clearance to check preload can
be obtained between differential and body by rais­
ing body a few inches by means of a jack or stand
placed under frame at rear.
4. Hold companion flange with tool J 8614-1 (Fig.
4A-7) and remove drive pinion nut and washer using
heavy duty socket.
5. Remove companion flange, using puller J 8614-2
and 3 (Fig. 4A-8).
6. Install new companion flange and washer and
nut. Hold companion flange with tool J 8614-1 and
tighten nut only a little at a time, stopping frequently
to check preload (step 3). Tighten nut to reading
noted in step 3| however, if reading obtained in step
3 was less than 12 lb. in., increase preload to 16
lb. in.
