How to Install the Air Lift LoadLifter 5000 Air Helper Springs on a 2012 Toyota Tundra


Today on our 2012 Toyota Tundra were going to install Part Number AL57299. First part of our install we have to shorten up the base of the jounce bumper. To do that, were going to remove one of the wheels from the axle. In this case were working on the driver side. Well go ahead and jack up the axle, remove the wheel and use a jack stand to help stabilize it. Next were going to go ahead and cut the stock jounce bumper.

Were going to measure it about 3/4 from the base, mark it, and then use a saw to go ahead and cut off the excess. Now well go ahead and start assembling the air spring itself. Well go ahead and take the 90 degree swivel air fitting, thread it together finger tight plus 1 and a 1/2 turns. Next well go ahead and attach the upper bracket. This will fit over the swivel air fitting through the slot in the bracket. Be sure to go by the instructions to make sure which set of holes you need to use.

Well go ahead and mark out what we needed for the left hand side. Then well use 2 3/8 flathead screws to attach it to the air spring. Then tighten them down as specified in the instructions. Now well go to the bottom of the spring, and well install a roll plate. Well fit that over the spring and then well put the lower bracket onto it.

When we install the lower bracket we want to make sure the flange side of the bracket is matching the square side of the upper bracket. Well install our hardware then tighten them down as specified in the instructions. Well go ahead and take the air spring compress it a little bit and wedge it between the frame and the suspension springs on the axle. Well work into place. Well work top in first and then the bottom half. Theres a hole in the bottom of the frame that the air valve will fit through.

Theres also 2 rivets in the bottom of the frame that the upper bracket will fit into as well. That will keep everything in alignment. Now also theres an emergency brake cable bracket on here. This is a good time to go ahead and push it forward as well. Now go ahead and install our clamps. The clamps are going to be identical on both sides. One of the clamp bars will go around the jounce bumper bracket and clamp into place and catch the edge. The other one on the inside edge of the frame will catch the inside edge of the frame itself just a little bit. It wont go very far in. On the bottom of the spring well go ahead and install our U-bolt and that will get a flat washer and non-lock nut. With everything loosely installed, well go ahead and tighten down the bolts and torque down as specified in the instructions. Well start from the top and work our way down to the bottom. Make sure the bolts are tightened evenly on both sides of the clamps and also on the U-bolts on the very bottom of the air spring. Well go ahead and unravel the air line and cut it exactly in two equal halves. Were using a tube cutter, because its important to have a square cut on the air line to ensure it will not leak when its installed in the air fitting. With our airline cut in half, well go ahead and take the cut in and push it into the swivel air fitting at the top of the air spring. Well pull back on it to make sure its tight. Then well go ahead and run our air line to the bumper. Next well go ahead and locate a place for our air line to install it in the bumper. This is a matter of personal preference. It can be located anywhere on the vehicle as needed. However in this case, were going to install it by the license plate frame. Using a right angle drill were going to follow the inside edge of the bumper where its an open part, and well use that as a guide. Were going to drill a 1/8 hole through the plastic of the bumper to the outside. Well do this on both sides of the vehicle. Then well go ahead from the outside in drill it out to a 5/16. Then we can go ahead and get our air line ready to run through the hole. First off, well install a nut on the airline fitting. Then a star washer. Push through the bumper. Then add the rubber washer, flat washer and another nut. Run down finger tight, and then go ahead and tighten them down. They dont have to be super tight. Just snug. When were done with the drivers side, well go ahead and repeat the same process over on the passenger side. When both sides are completed, well go ahead and add air to them and see how they inflate. Now lets go ahead and take it for a test drive. With that, that will finish it for our install Part Number AL57299 form Air Lift, LoadLifter 5000 on our 2012 Toyota Tundra. .
