FRONT WHEEL BEARING MAINTENANCE
AFFECTED VEHICLES
• 2011-2016MY NPR-HD Trucks
• 2012-2016MY Isuzu Stripped Chassis (Reach Vans)
Equipped with 3.0L (4JJ1) and 5.2L (4HK1) Diesel Engines
INFORMATION
CONDITION
In some 2012-2016MY Isuzu Stripped Chassis (Reach Vans) and 2011-2016MY NPR-HD
diesel trucks, the original factory-installed grease in the front wheel bearings may degrade
under certain circumstances. If left unattended, the front wheel bearings could eventually
seize or loosen. Typically this condition is preceded by a noticeable growling noise and can
be avoided with timely servicing of the front wheel bearings.
CORRECTION
If a vehicle has 60,000 miles or less, Isuzu will replace the front wheel bearing grease. The
front wheel bearings will also be inspected and, if they are found to have been damaged due
to grease degradation, they will be replaced. This inspection and replacement will be
performed one time up to 60,000 miles free of charge. This free of charge service will be
discontinued 24 months from the date of this notification.
DEALER RESPONSIBILITY
Dealers are to service all vehicles (with 60,000 miles or less) subject to this program at no
charge to customers - regardless of ownership or the age of the vehicle. Customers who
have recently purchased vehicles sold from your vehicle inventory, and for which there is no
customer information indicated on the dealer listing, are to be contacted by the dealer.
Arrangements are to be made to make the required correction according to the instructions
contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use
in contacting customers. Program follow-up cards should not be used for this purpose, since
the customers may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in
your dealership for service, you must take the steps necessary to be sure the program
correction has been made before selling or releasing the vehicle.

HUB INSPECTION PRECEDURE
1. Clean the grease from the spindles,
knuckles, hubs, and the inner and outer hub
bearings. Inspect the grease for metal
powder and/or particles, as these may
indicate bearing damage. If found, continue
inspection to find source.
2. Inspect the inner and outer hub bearings
checking for: deformity, burning, rust,
flaking, pitting, peeling, scoring, surface
roughness, deep scarring, or deep slide
marks. If any of the above conditions are
present, replace bearing.
3. Inspect bearing cage for; deformity,
cracking, scarring, and wear at contact
surface of ribs. If any of the above
conditions are present, replace bearing.
4. Press bearing cage against rollers with one
hand and the inner bearing race against
rollers with the other hand, apply pressure,
and rotate bearing. Bearing should rotate
smoothly. If roughness is felt, verify
cleanliness. If dirty, clean bearings. If
bearing is clean, continue with inspection.
5. Inspect inner and outer hub bearing races
for: deformity, cracks, peeling, rust, surface
roughness, vermiculation, deep scarring,
deep slid marks, uneven wear marks across
surface. If any of the above conditions are
present, replace bearing.

NOTE: If discoloration is only on the contact portion of rollers or races and light brown
in color, this is normal. This is caused by burned grease. DO NOT REPLACE
BEARINGS.
NOTE: If it is suspected that the bearing will need to be replaced, be sure to always
use the races provided with the new bearings. If you are still unsure or have questions
regarding the bearings in this campaign, please contact Isuzu Technical Assistance or
your DSPM.

WHEEL BEARING REPLACEMENT
1. Remove the damaged bearing to be replaced, by driving the inner and outer bearing
races out of the hub.
2. Drive the outer race out from the opposite side. See Figure 10.

Figure 10
(1) Hub
(2) Disc
(3) Brass Bar

3. Lightly grease the new bearing races, using Special Tools: J 8092 (Tool Grip), J 35712
(for inner bearing) and J 35713 (for outer bearing); seating them completely into the hub.
See Figure 11.

HUB ASSEMBLY AND BEARING PRELOAD PROCEDURE
NOTE: If the bearing was replaced, be sure to grease and reinstall the inner and outer
races of both inner and outer bearing.
1. Apply a 5mm layer of grease across the top of the bearing races and completely fill the
hub cavity, and completely grease the inner race of the inner bearing (See Figure 15).
Fill the hub cap half way with grease and taper to the edge of cap. Overfilling cap will
create a hydraulic condition not allowing the hub cap to fully seat. See Figures 12 and
13.
CAUTION: Do not apply grease on fitting surface between the hub cap and hub
assembly. See Figure 14.
2. Pack both inner and outer front wheel bearings using a lithium-based, NLGI No. 2 or
No. 3 grease with a dropping point equal to or greater than 500°F (260°C).

4. Install the spacer onto the knuckle; the concave side of the spacer faces the knuckle.

Figure 16 – Correct Spacer Direction

5. Install the hub assembly onto the knuckle.
6. Install the outer wheel bearing, bearing washer and nut onto the knuckle, and handtighten.
7. Turn the hub to the left and right several times to stabilize the bearing while continuing
to tighten the nut by hand.
8. Gently tighten the hub nut to the specified torque. The tightening torque is the same
for both new bearings and reused bearings.
Tightening Torque: 110 Nm (81 lb ft)
CAUTION: DO NOT use air tools for tightening.
9. Rotate the hub three (3) times in the forward direction.
10. Gently loosen the hub nut no more than 90°.
IMPORTANT: If you loosen the hub nut to the point where there is noticeable
free-play in the hub, you must restart the procedure from Step 7.
11. Tighten the hub nut to the specified torque. The tightening torque is the same for both
new and reused bearings.
Tightening Torque: 15 Nm (11 lb ft)
12. Rotate the hub three (3) times. If the hub does not rotate, has resistance, abnormal
heaviness, or is still loose, repeat Steps 7-10.
13. Install a new cotter pin and firmly bend it.
CAUTION: If the hub nut groove and cotter pin hole do not align, align the hole
by tightening the hub nut until the cotter pin fits through the pin hole.

8

14. Apply grease on the outside of the outer bearing (See Figure 17).
IMPORTANT: Be sure the grease inside the hub cap directly contacts the grease
on the outer bearing.

Figure 17 – Grease Outside Outer Bearing

15. Apply an even layer of ThreeBond 1215 (p/n 2-90067-710-0) sealant or equivalent
around the outer edge of the hub cap and install.
16. Clean the rotors with parts cleaner.
17. Return the brake caliper and bracket assembly to its original position (see Figures 18
and 19). Tighten the caliper mounting bracket bolts to the specified torque.
Tightening Torque: 221 Nm (163 lb ft)
