Skyjacker TTU25 - Manual (Page 2)

REAR INSTALLATION
1. Raise the rear of vehicle and place jack stands under the frame so that the rear clear the ground.
2. Remove the rear tires and wheels.
3. Disconnect the rear shocks from the axle.
4. Support the rear axle with a floor jack and loosen all four U-bolts. Remove two U-bolts and clamp from one side.
5. Lower the axle away from the spring so that the drum is clear of the leaf Spring. Bend the spring clamps down and away
from the spring. Remove the plastic clips from the spring clamps.
6. With the appropriate clamps, clamp the spring together and remove the bolt securing the springs together; you may have
to use Vise-Grips to hold the head of the bolt.
7. Carefully remove the clamps and note the position of the springs.
8. Sandwich the add-a-leaf between the four stock springs, the springs should stack up shortest to longest with the longest
on top. Install the supplied bolt from the bottom up and tighten. (You will have to use C-Clamps to compress the springs
together.)
9. Raise the rear axle onto the spring assembly; make sure that the spring bolt head seats into the axle pad. Cut off the
excess thread 1/8” above the nut so that the stock bump stop will fit flush with the top spring when bolted together.
10. Install the U-bolts and clamps, just starting the nuts.
11. Repeat steps 4 thru 8 for the other side of the axle.
12. Tighten the U-bolt nuts evenly to factory spec so that you have the same thread showing on all U-bolts.
13. Bend the spring clips over the new spring bundle. You may have to use a heavy hammer to do this correctly; the spring
clips should be tight.
14. Reconnect the shocks to the rear axle.
15. Install the rear tires and wheels.
16. Retighten the U-bolt nuts after 500 miles.

Final Notes:
- After installation is complete, double check that all nuts and bolts are tight. Check to ensure there is adequate clearance
between all rotating, mobile, and fixed members.
- Ensure there is adequate clearance between exhaust and brakelines, fuel lines, fuel tank, floor board, and wiring harness
es. Check steering gear for interference and proper working order. Inspect brakelines for damages and adequate clear-
ance.
- With the vehicle on the floor, cycle steering lock to lock and inspect steering, suspension, driveline
and brakeline systems for proper operation, tightness and adequate clearance.
- Have headlights readjusted to proper settings.
- Have a qualified alignment center check and realign to factory specifications.
