DIAGNOSIS
1. Test-drive the vehicle on a dirt or gravel road. From
a stop, accelerate hard to make the front tires slip.
• If the rear differential makes noise, go to the
REPAIR PROCEDURE.
• If the rear differential does not make noise, go to
step 2.
2. Test-drive the vehicle in a circle on a paved, open
parking lot at about 10 mph while holding the
steering wheel in a full-lock position.
• If the rear differential makes noise, go to the
REPAIR PROCEDURE.
• If the rear differential does not make noise,
disregard this bulletin and troubleshoot other
causes.
REPAIR PROCEDURE
1. Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or Neutral) until the radiator fan
comes on.
2. Raise the vehicle on a hoist.
3. Circulate the Dual Pump Fluid through the clutch
assembly:
• On A/T models: Apply the parking brake, put the
transmission into D
4
, and let the vehicle idle for 5
minutes.
• On M/T models: Put the transmission into 1st
gear and engage the clutch. Slowly apply the
parking brake until just before the engine stalls.
Let the engine run like this for 5 minutes.
4. Engage both differential pumps:
• On A/T models: Release the parking brake, and
let the vehicle idle in D
4
for 5 minutes.
• On M/T models: Release the parking brake, and
let the vehicle idle in 3rd or 4th gear for 5
minutes.
5. Turn the ignition switch OFF, and put the vehicle in
Park or Neutral.
6. Drain the rear differential.
• If the fluid looks and smells burnt, go to step 8.
• If the fluid looks normal and does not smell, refill
the differential, repeat steps 3 thru 6 two more
times, then go to step 7.
7. Test-drive the vehicle as you did for DIAGNOSIS.
• If the differential is still noisy, go to step 8.
• If the noise is gone, return the vehicle to the
customer.
8. Remove and disassemble the rear differential.
Refer to section 15 of the 1997 CR-V Shop Manual.
