This B&M Cast Aluminum Rear
End Cover has been designed to
work on most vehicles equipped
with a Dana 80 style axle. The B&M
Cast Aluminum Rear End Cover
provides several advantages over
stock factory covers. The extra
capacity provides increased oil
volume and added cooling, while the
thick
aluminum construction
increases case rigidity. The
reinforced center bar, along with the
load bolts, prevents bearing cap
deflection under severe loads. The
magnetic drain plug feature allows
regular gear oil changes without the
usual mess, and limits ferrous debris
from circulating in the axle.
INTRODUCTION
This rear end cover can be installed
in about an hour by carefully
following the instructions. It is
suggested that the vehicle be
allowed to cool off for a few hours to
avoid burns from hot oil and parts.
The vehicle should be off the ground
for ease of installation - jack stands,
wheel ramps or a hoist will work
fine. MAKE SURE VEHICLE IS
FIRMLY SUPPORTED - DO NOT
WORK UNDER A VEHICLE IF IT IS
SUPPORTED BY ONLY A JACK!
Try to raise the vehicle 1-2 feet so
you will have plenty of room to
work. Also, have a small box to put
bolts in and a drain pan to catch
oil.
INSTALLATION
STEP 1. Clean axle housing cover
area from dirt and other debris.
NOTE: On some vehicles it
might be necessary to remove
some parts (e.g. sway bar,
panhard rod) to make the
installation of the cover easier.
STEP
2. Place a drain pan
underneath the axle housing.
STEP 3. Loosen the axle housing fill
plug with a 1/2
” square ratchet (See
Figure 1).
STEP 4. Remove all the bolts
except one at the top. Loosen the
remaining bolt but do not remove.
