Item 7: Differential Pinion Shaft Removal Note 1. Move the differential pinion shaft out far enough to remove the U-washers. Replace the shaft and install the lock bolt finger tight when U-washers are removed. Item 8: U-washer Removal Note 1. CAUTION: Do not damage the rubber O-rings in the axle shaft grooves. Remove the U-washers. 1. Push the axle shafts inboard. 2. Remove the U-washers. Item 10 and 11: Wheel Bearing Oil Seal and Axle Shaft Bearing Removal Note 1. CAUTION: Never remove the wheel bearing oil seal by itself. Always remove the wheel bearing oil seal and the rear wheel bearing at the same time. For the 8.8 inch rear axle, use the special tools to remove the rear wheel bearing and wheel bearing oil seal. 2. CAUTION: Never remove the wheel bearing oil seal by itself. Always remove the wheel bearing oil seal and the rear wheel bearing at the same time. For the 9.75 inch and the 10.25 inch rear axles, use the special tools to remove the rear wheel bearing and wheel bearing oil seal. Item 11: Axle Shaft Bearing Installation Note 1. For the 8.8 inch and the 9.75 inch rear axles, use the special tools to install the rear axle wheel bearing. 2. For the 10.25 inch rear axle, use the special tools shown to install the rear axle wheel bearing. Item 10: Wheel Bearing Oil Seal Installation Note 1. Use the special tools shown to install the rear wheel bearing oil seal. Item 8: U-washer Installation Note 1. CAUTION: Do not damage the rubber O-rings in the U-washer grooves. Install the U-washers. 1. Position the two U-washers on the button end of the axle shafts. 2. Pull the axle shafts outward.

SYMPTOM A squealing or moaning noise is heard from the rear of the vehicle when the front tires are slipping during acceleration or when the vehicle is turning. PROBABLE CAUSE Water entered the differential through the breather tube and contaminated the differential fluid. CORRECTIVE ACTION Flush the differential with new fluid and/or replace the differential clutch set. PARTS INFORMATION Breather Tube Assembly: P/N 41130-P6R-020 Differential Clutch Set: P/N 48010-P6R-305 Rear Differential Mounting Bracket: P/N 50710-S10-A01 Honda Dual Pump Fluid: P/N 08200-9002 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 D4, 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 D4 for 5 minutes. • On M/T models: Release the parking brake, and let the vehicle idle in 3rd or 4th gear for 5 minutes.

NOTE: Unless noted, the procedures in this section apply to both the conventional differential and the Truetrac® differential, though most of the illustrations used in the procedures show the conventional differential. The Model S135 rear axle features the following: a hypoid design differential ring gear and pinion a two-bearing overhung pinion mounting full-floating axle shafts a steel differential housing a front mounted removable one-piece carrier housing a conventional differential assembly or a Truetrac® limited slip differential assembly The trademark shows the company logo, and identifies the location of the manufacturing facility. CAUTION: Never mate a differential ring gear and pinion together that does not have the same matched set numbers. Always install a new matched set if discarding either the differential ring gear or the pinion. A corresponding number marked on the differential ring gear and pinion identifies them as a matched set. The manufacturer’s date identifies the gear set’s date of fabrication. The tooth combination identifies the number of teeth on the pinion and the number of teeth on the differential ring gear. A tooth combination of 41-11, for example, would indicate that the pinion has 11 teeth and the ring gear has 41 teeth that results in a 3.73:1 ratio.

BACKGROUND A moaning or groaning comes from the rear differential when making a sharp or tight turn at low speeds. PROBABLE CAUSE Contamination in the rear differential fluid. CORRECTIVE ACTION Replace the rear differential fluid, and burnish the rear differential clutches. REPAIR PROCEDURE: 2002–04 MODELS 1. Replace the rear differential fluid: • Refer to page 15-13 of the 2002–04 CR-V Service Manual, or • Online, enter keywords REAR DIFF, and select Rear Differential Fluid Inspection and Replacement (4WD) from the list. 2. Raise the vehicle on a lift until all four wheels are completely off the ground and can rotate freely. 3. Start the engine, and let it idle until the radiator fan cycles on and off twice. 4. Burnish the rear differential clutches:

SYMPTOM A screech or whine from the rear differential when making a tight turn at low speed (for example, in a parking lot when 4WD engages). PROBABLE CAUSE The differential fluid is contaminated or broken down, providing insufficient lubrication. CORRECTIVE ACTION Replace the dual pump fluid, and test-drive the vehicle. If necessary, replace the rear differential clutch, replace the oil pump assembly (1997 model only), and add a flow collar. REPAIR PROCEDURE 1. Drain and refill the rear differential with Dual Pump Fluid. 2. Check the tires for proper inflation (recommended cold inflation front and rear is 26 psi) and any variation in tire size or type. 3. Test-drive the vehicle in a parking lot. Make tight, low-speed turns. • If the noise is eliminated, return the vehicle to the customer. • If the noise is still present, go to step 4. 4. Remove the rear differential assembly (see page 15-16 of the 1997–01 CR-V Service Manual). 5. Remove the torque control differential case, then remove and discard the 30 mm shim and the clutch assembly (see steps 1 thru 10 on pages 15-20 thru 15-22 of the service manual).
