BMR Suspension BMB001 - Manual

DELRIN BODY MOUNT BUSHINGS
BMB001 – 1967-1981 Camaro and Firebird
RECOMMENDED TOOLS:
Hydraulic Jack and stands
¾” wrench
Sockets: ¾”, 15/16”
Pry-bar
INSTALLATION:
1. Lift vehicle and support with jack stands under the rocker pinch seams. The wheels do not need to be off the ground, there
just needs to be enough room to work under the vehicle. If using a drive-on service lift, the vehicle may be left supported by
the suspension.
2. Choose a side to begin and loosen both body mount bushings using a 15/16” socket. Leave the forward bolt loose but do not
remove it. The frame should separate from the body slightly.
3. With the rear bolt removed, take out the factory body mount bushing. It may be necessary to pry the frame away from the
body in order to remove and replace the bushing. The bushing is composed of an upper and lower half that “sandwiches” the
subframe. Once removed, inspect the area and repair if necessary (NOTE: The factory sub-frames have a tendency to rust in
these areas and your new Delrin bushings need a secure mounting point to properly do there job).
4. Your BMR Delrin Body Mount Bushing kit is composed of 2 types of bushings, front radiator core support bushings (smaller
diameter) and the main bushings (larger diameter). Insert the upper portion of the larger bushing in to the frame mounting
hole from above. Now place the lower half over the protruding portion of the upper bushing, effectively “sandwiching” the
subframe between them. Insert the provided bolt, washer and lock washer but leave the bolt loose.
5. Proceed to the middle bushing (firewall bushing). Remove the bolt and, if possible, the factory bushings. It may be
necessary to pry the frame away from the bushing in order to remove and replace this bushing. Duplicate the above procedure
and then snug both bolts but do not tighten them yet.
6. Duplicate steps 2-5 on the other side of the
vehicle.
7. Tighten all 4 body mount bolts to 150
ft/lbs. then proceed to the core support
bushings at the front of the vehicle.
8. These bushings are not as accessible but
can generally be done without removing
other components. It may be easier for
some to remove the battery and battery tray
to gain better access to the passenger side.
9. Using a ¾” wrench and socket, remove
both front mounting bolts.
10. Place a jack under the core support and lift
just enough to remove the factory
bushings. NOTE: sometimes it will be
necessary to remove the front bumper and
bumper brackets in order to get the core
support high enough.
11. Inspect the area and repair if necessary
(pay special attention to the passenger side.
The battery can cause significant rust in the
body mount area sometimes requiring new
core support mounts).
12. Insert the Delrin body mount bushings, capturing the core support mount in between them. Place one of the supplied washers
on top and bottom, then insert the bolt and nut. Tighten to 120 ft/lbs.
13. Re-assemble any previously removed items, lower vehicle.
