24. If bolting the cross-member into place,
begin on the passenger side. Position the
provided frame reinforcement plate as
shown in Image 12 on the following page.
The outside perimeter of the reinforcement
plate should match that of the shock cross-
member.
25. Mark the frame at the center of the slot
using a grease pencil or paint marker.
NOTE: Due to vehicle production
variance, it may be necessary to trim the
forward portion of the reinforcement plate
slightly in order to make it fit squarely to the
shock cross-member. The factory shock
reinforcement on the frame rail may prevent
proper plate alignment if the reinforcement
plate is not trimmed. Plate alignment is
very important to insure the holes are
drilled in the proper location to line up
squarely with the shock cross-member holes
on the other side of the frame rail.
26. Center-punch the marks on the frame to
provide a drill centerline so the drill bit
doesn’t wander.
27. The recommended (and easiest) way to drill
through the frame rails is with a step-type
drill bit. Using a ½” bit (or step bit) drill
through the outer portion of the frame rail as
shown in Image 13. Take extra care to
angle the drill correctly before drilling
through the other side of the frame rail.
Continue drilling through the frame rail until
the bit starts to appear through the inner bolt
holes of the BMR cross-member. In most
cases, the holes in the cross-member will
“self-align” the drill bit, forcing the bit to center itself in the hole.
28. Once both ½” holes are drilled through the sub frame, it is necessary to enlarge the outer
frame holes to ¾” to allow insertion of the provided frame reinforcement inserts. Using
either a ¾” drill bit or a step bit (much easier), enlarge ONLY the outer holes in the frame
rail. (Image 14)
