CROSS-MEMBER INSTALLATION (Cont.)
7) Thread the supplied 5/8” bolt, washer and lock washer into the body and snug the bolt
just enough to allow the frame bracket to rotate around the axis of the bushing.
8) Repeat steps 4-7 for the passenger side. At this stage both mounts should be installed and
you can mount the cross-member. Lift the cross-member into place and insert the
supplied ½” x 4.5” bolts, (8) stainless washers, and nuts.
9) Tighten the body mount bolts to 150 ft/lbs.
10) Center the cross-member to the driveshaft then tighten the (4) cross-member bolts.
TORQUE ARM INSTALLATION INSTRUCTIONS:
1) Remove the differential drain plug or loosen the cover bolts to drain the gear oil from the
differential.
2) If it was not necessary to remove the cover previously, remove the 12 bolts from the
differential cover and remove the cover.
3) Using a gasket scraper, remove all
gasket material from the cover and the
differential.
4) Thread the four supplied 5/16” studs into
the differential at the four corners. All
studs should bottom out and should
thread in to the same depth. If not, run a
5/16-18 bottoming tap through the holes
in the differential.
5) Apply a thin bead of RTV Black or Grey
gasket silicone onto the differential
gasket mating surface. Install one of the
supplied gaskets.
6) Apply another thin bead of RTV on the exposed gasket surface. Position the BMR torque
arm mounting plate onto the rear end with the torque arm mounting points facing forward
as in Image 1 above.
