Here are the specifics on the 1 inch thick Teraflex pucs I installed in the front of my 2013 JKUS to level it out. I did not install anything in the rear. I just wanted to level the Jeep.
Tires are 255/75/17 Cooper Discoverers AT3’s mounted on stock Rubi wheels.
1 each 10mm combo wrench
2 each 18mm combo wrenches
1 each ½ drive 18mm shallow socket
1 each ½ drive ratchet
1 each torque wrench (up to 100 ft. lbs.)
1 each ½ drive deep well ¾ inch socket for lug nuts. Also might need a 13/16 inch if lugs are not factory.
1 each 18 inch pry bar
2 floor jacks if available. Makes it easier to lift front evenly
2 substantial floor stands
2 each 12 to 18” bungee cords
1. Loosen lug nuts on front rims before lifting Jeep.
2. Place floor jack under front differential on driver’s side.
3. Place 2nd floor jack under spring perch on passenger side.
4. Lift Jeep as high as floor jacks will lift front evenly.
5. Place jack stand under frame on driver’s side and passenger side at the front body mount. This is located almost under the front doors at the hinge locations on both the driver and passenger sides. Make sure jacks are seated firmly.
6. Before releasing tension on floor jacks, loosen lower shock bolts with 18mm combo wrench and 18mm socket/ratchet.
7. Loosen sway bar lower bolts with same size wrenches.
8. Remove lower brake line bolt using 10mm wrench. I also removed the upper brake line bracket bolt at the frame just in case extra movement was needed.
9. With Jeep supported firmly on jack stands, remove just enough pressure on floor jacks to allow for the removal of the lower shock bolts on both sides. You can tell when they can be removed, as they will be fairly easy to turn by hand. If they will not turn by hand release additional pressure on the floor jacks until they can be removed.
10. Use the bungee cords and pull the lower part of the shock and the brake line back towards the frame to get them out of the way. The bungees will fit in slots in the frame. Make sure you do not crimp any brake lines.
11. Remove the sway bar links in the same manner. Pay attention to the physical location of parts so they can be re-installed as removed. Pull them out of the way.
12. I did not loosen the control arms. I think that is personal preference. The front should not be “preloaded” from this. If after installing the pucs and driving for a few miles you do not like the ride then you can loosen and re-torque the control arm bolts. I chose not too and mine rides no different from the day I brought it home.
13. If you have the Jeep sitting high enough on the jack stands the rest should be easy.
14. Lower the front axle as much as possible evenly. Make sure the brake lines do not have any strain on them.
15. I started with the driver’s side. First thing is to note where the spring end notch is located. It is paramount that once the spring is reinstalled that it is “seated” in this indention. If it is not, the Jeep will sit one sided when looking at it from the front. See if you can move the spring. If not, jack the passenger side up a few strokes. This should allow additional angle on the driver’s side. If the spring feels loose but still will not come off of the lower mount use the pry bar to help it up. Use extreme caution when removing or installing springs. They are very dangerous if they are preloaded.
16. After removing the spring. (I “screwed” mine out through the bottom.) Remove the factory puc and install the Teraflex puc. Inspect the factory puc for wear and degradation. Replace if excessive worn. The main thing here is to install the larger diameter puc on the Jeep first. Reinstall the factory puc. Make sure the pucs are stacked flat against each other.
17. “Screw” the spring back up into position and ensure that spring end is seated in the lower perch indention. Springs can only go in one direction. They are top/bottom specific. After the spring is installed, apply slight pressure under the axle with the floor jack to hold the spring in place. Once again, verify the spring is seated properly. If not, lower the axle again and adjust.
18. Do the same procedure for the passenger side. Again, use extreme caution when dealing with springs. They are dangerous.
19. After installing pucs on both sides, apply pressure to raise axle evenly with both floors jacks to allow for shock bolt installation, sway bar link connection, and brake line bracket reinstall.
20. Tighten lower shock bolts.
21. Tighten lower sway bar links. They should be mounted on the “inside” of the sway bar towards the center of the Jeep.
22. Install brake line brackets and tighten.
23. Walk away from Jeep for a few minutes and come back. Look at every joint and physically touch each location to ensure all pieces touched to install pucs are secure.
24. Install wheels and torque in a crisscross pattern to 95 ft. lbs. as described in owner’s manual.
25. Remove jack stands.
26. Remove floor jacks.
27. Go for a ride down the bumpiest road that you know of. I think this helps to ensure all is “seated”. If you hear any noises or feel anything that was not heard or felt before, get it home and check all joints touched in previous steps to find what is loose.
28. If all is cool on the bumpy road, get on a section of highway and make sure all feels good. If all is good, you are done! Enjoy the level look and JEEP SAFE!
