Synergy JK OE Replacement Drive Shaft - Manual (Page 3)

9. Remove the T-case yoke nut and yoke. A puller is normally needed to remove the
yoke from the output shaft.
10. The new yokes may come with or without dust shields. If the yokes have dust
shields, use them. If they do not come with dust shield, they are not required, do not
try to re use your original one.
11. The new yokes may or may not be machined for the factory O-ring that is under the
nut. If it is machined for the O-ring, reuse the original O-ring, if not use some
silicone sealer on the output shaft splines and under the nut.
12. Install the new T-case yoke, tighten the yoke nut to 110 ft-lbs, and use some red
loctite on the yoke nut.

13. Grease the u-joints and center ball of the CV joint if they are greaseable. It is very
difficult to access the grease zerk when installed on the vehicle so grease them before
you install the CV joint.
14. Install the new drive shaft using the u-bolts and 5/16 bolts for the 1310 or metric 12
pt bolts for the 1350 CV flange. Use some blue loctite on the u-bolts and CV bolts.
15. For a 1310 CV, tighten the 5/16 bolts CV bolts and axle yoke U-bolts to 8.5 ft-lbs. A
tip to install them is to tighten the nuts until the lock washer is flat then tighten an
additional ¼ turn.
16. For a 1350 CV, tighten the 12 pt metric bolts to 50 ft-lbs and the axle yoke U-bolts to
12 ft-lbs. A trick to install the u-bolts is to tighten the nuts until the lock washer is
flat then tighten an additional 1/3 turn.
