Inventory that you have all of the parts for your order If you are missing partsor have incorrect parts contact Artec Industries Immediately @(855)-278-3299 M-F from 8am-5pm MST If it is after those hours please EmailSales@Artecindustries.com
Place wheel chocks at the rear wheels of the vehicle. Break free lug nuts on rear wheels (Do notfully loosen or remove lug nuts yet.)
With the vehicle sitting on the ground, Measure your rideheight at the frame and height of the centerline of the axle, Also take measurementof your wheel base.
(Make a note of this for later.)
Jack up the front of the vehicle and set the axle on Jackstands, Remove the rear wheels from the vehicle, With the wheels removed Jack the vehicle upagain. Securely place tall jack standsunder the frame behind the LCA or Leafspring mounts at the previously measurement of ride height. Place a 2nd sent ofjack stands under the front axle.
Remove the existing front axle from the vehicle
Prep axle the truss will be welded onto by removing allmounts and paint/ rust. Once the axle isprepped. Slide new axle under the vehicle and place on jack stands at themeasurement of what the centerline height was at ride height also make sure itis set to the wheelbase you will be using.
Using another jack stand or block of wood set under the Pinionof the axle, Set the Caster angle and pinion to desired angle of your build to ensure itdoes not get changed . Now place the truss on top of the axle so it is levelwith the ground and not tilted forward or backward (Ifyour truss is angled it can cause upper arm mounts or the truss to twist offunder load) You may need to trimsome gussets on the truss to allow it to sit level depending on your wheelbaseand pinion angle. (Ford 9” trusses will need to be trimmed to fit your axle)
With the truss set level on top of the axle tack weld Thetruss ends to the axle tubes.
With the truss tacked into place Pull the axle from underthe vehicle to allow more space for welding. Once the axle is pulled from under the vehicle. Heat the axle to about 400 degrees Startto weld the gussets to the axle andtruss .When welding, Start on one side of the axle, Weld a small amount, Thenmove on to the opposite side of the axle to allow each side to cool. This willhelp prevent warping .Stitch welding is preferred and welding every inch of every seam is notnecessary. Grind and clean the rosette welds on the axle. If your truss has abridge you may need to Trim the bridge depending on your pinion angle and weldit to the truss. (Optional) Stitch weld the axle tubes to the ends of the casting for addedaxle strength and to prevent the axle tubes from twisting. If you haveany Control arm mounts, Shock mounts, Coil over tabs, Track bar mounts thatneed to be welded on to the axle youwill need to place the axle under the vehicle on jack stands at ride height anddesired wheelbase an weld them on at this time in their proper location foryour specific build. Once all of thewelding is complete you will wrap theaxle in a welding blanket to slowly cool overnight.
Clean the Truss and axle of any machining oils and Prep forpaint or powder coat.
Install the axle back under the vehicle and place on jackstands. Install the wheels on the vehicle and tighten the lug nuts (Do nottorque them down yet.) Lift the vehicleand remove all of the jack stands and set the vehicle on the ground. with the vehicle on the ground check all ofthe bolts and lug nuts are torqued to proper specs. we recommend drawing a lineon the nut and bolt heads and where they are mounted for quick reference whenchecking for tightness after 50 miles .
