Upper Bar Installation Jig
This jig has been supplied to aid in the installation of the upper 4 link bar. It can be
temporarily used to properly align, locate and weld the tabs onto the axle. It will also ensure
that the mounting bolts are parallel to the ground.
Follow the diagram below to set the jig to the same length as the upper bar, use the 3/8” x 3/4”
bolt and nuts to set the length.
Position the axle at ride height. Center the axle left to right between the quarter panels. Set
pinion angle.
Bolt one end of the jig to the cradle using a 5/8” x 2 ¾” bolt.
Using another 5/8” x 2 ¾” bolt, fasten the axle tabs to the other end. The tabs must be bolted
to the outside of the jig.
Swing the bar down letting the tabs rest onto the axle. Trim the brackets as necessary to
minimize the gap to be welded.
Check pinion angle, ride height and axle center. Tack-weld the tabs in place.
Remove jig and install upper bar.
Repeat this process for the other side.
Recheck pinion angle, ride height and axle center. (Sound familiar?)
After the tabs have been tack welded on both sides, remove the upper bars to avoid melting
the rubber bushings. Let the axle drop down for better access to the tabs. Lay 1” welds on the
inside and outside of the tabs. Skip around from one side to the other to avoid overheating
the tube.
