Important Notes:
To reuse your factory Oil pan skid plate, a spacer will be required to lower
the skid plate. The spacers need to be roughly a ½ inch thick.
Instructions are written for ZR2 models. If you don’t have a ZR2, the install
is the same, but some tool sizes will be different.
Step 1: Jack the front of the vehicle up and support the vehicle using
proper Jack Stands.
Step 2: With the vehicle supported on Jack Stand, remove the front wheels
and place out of the way.
Step 3: Starting on the passenger side. Remove the two lower strut bolts
from the lower arm with a 15mm socket and ratchet. Using a 13mm socket and
15mm wrench, remove sway bar links.
Step 4: Using an 18mm socket and ratchet, remove the brake caliper from
steering knuckle. Be sure to tie up the caliper off to the side to prevent
damage to the brake line. Step 5: Remove the T30 torx screw from
the wheel speed sensor, along with the 10mm head bolt holding the wheel speed
sensor wire. The speed sensor can be gently removed from the steering knuckle
and moved out of the way. Also remove the outer tie rod end using the 21mm
socket and ratchet.
Step 6:
Remove the nut attaching the upper arm to the knuckle with an 18mm socket and
ratchet. The upper arm is under some tension and may suddenly spring up when
the nut is removed. Be cautious when removing the nut.
Step 7 : With the upper control arm
removed from the steering knuckle, you can now remove the 36mm axle nut and
washer. Next remove the lower ball joint nut using the 26mm socket and
ratchet. A few light taps on the steering knuckle should release it from the
lower ball joint. You can know slide it off the spines of the CV axle and
place to the side.
Step 8 : Using the 15mm wrench you can
remove the three nuts at the top of the shock and slide the shock out and
place out of the way. (You do not need to remove the shock, but it does offer
some more room to work)
Step 9: Using the pry bar, place the tip between inner CV Axle joint and
the differential housing. Apply steady pressure on the CV axle while
simultaneously pulling outward on the axle assembly. This should release the
C-clip on the axle assembly inside the differential. Place the axle assembly
out of the way, using caution to not damage the threads or splines.
Step 10:
Repeat steps 3-9 on the driver’s side.
Step 11: Using the 15mm socket and ratchet, remove the oil pan skid plate
so you can access the differential. Place a floor jack under the differential
so the jack just touches the bottom.
Step 12: With the differential supported by the jack, you can now remove
the front differential brackets on each side using the 21mm socket and 15mm
socket. You will reuse the 21mm head bolts, however, the 15mm head bolts along
with the factory brackets won’t be reused.
Step 13:
Locate the supplied differential brackets and bushings. Lightly grease the
bushings and install them into the new brackets. Using the supplied Flange
head bolts and the factory 21mm head bolts, loosely install the new brackets
on to the differential and frame. With both brackets loosely installed, you
can now tighten them down starting with the 16mm Flange head bolts.
Step 14: Now that the new diff drop brackets are installed and all the
fasteners are tight, you can begin reassembling the suspension. Follow Steps
3-11 in reverse order. When reinstalling the CV axle assemblies, make sure the
splines that go inside the differential are clean before installing. To
install the axle assemblies, insert the splines into the differential,
rotating the axle back and forth as you slide it in will ensure the splines
align. Once the splines are aligned you can firmly push the axle assembly
inward. You will hear a clunk and feel the axle pop into position.
Important:
After reassembly, make sure you pump the brake pedal several times before
putting the vehicle in gear. Since the calipers were removed, you need to push
the pads back up to
rotor. Not doing this can cause momentary loss of brakes.
Always torque fasteners to OEM specifications.
