The axle housing assembly consists of a cast-aluminum center section, a removable cast-aluminum axle housing tube (3B210), and a differential housing cover (3N136). Both the axle housing tube and the differential housing cover use silicone sealant as a gasket. The hypoid-design gearset consists of an 8.8-inch ring gear (3A397) and a pinion gear (3N175). Two opposed tapered roller bearings support the drive pinion in the axle housing. A drive pinion collapsible spacer (4662), located on the pinion shaft, maintains pinion bearing preload. The pinion nut adjusts the preload. Differential bearing shims (4A451), located between the differential bearing cups (4221) and the axle housing, adjust the differential bearing preload and the ring gear backlash. The differential case (4205) is a one-piece design with two openings to allow for assembly of the internal components and lubricant flow. Two opposed tapered roller bearings (differential bearings ) support the differential case in the axle housing. Removable differential bearing caps (4224) retain the differential assembly in the axle housing. Inside the differential case, the differential pinion shaft (4211) supports two differential pinion gears (4215). The pinion gears engage the differential side gears (4236), to which the left axle shaft (3A381) and the axle cluster gear shaft (7L253) are splined. The differential pinion shaft bolt retains the differential pinion shaft in the differential case. An embossed metal tag, bolted to the rear face of the RH axle tube, contains front axle identification information. CAUTION: Actuate the front drive axle with the wheels in a straight ahead position, and at light throttle only. A front axle actuator motor assembly (7G360), controlled by an instrument panel-mounted switch, actuates the front drive axle.

1. Remove the differential case (4204). For additional information, refer to Differential Case in this section.
2. NOTE: The differential bearings (4221) need not be removed to overhaul the Ford limited slip differential. If bearing removal is required, use the special tool 205-D072 (D97L-4221-A) and special tool 205–D019 (D80L-630–8) for differential case bearings.
NOTE: The anti-lock speed sensor ring cannot be reused once removed. Remove the differential pinion shaft lock bolt and remove the differential pinion shaft (4211). If required, remove the differential ring gear and anti-lock speed sensor ring.

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.

FORD: LINCOLN: 2002-2005 Crown Victoria, Mustang, Explorer 2002-2005 Town Car 2003-2005 Expedition 2003-2005 Navigator 2004-2005 F-150 MERCURY: 2002-2005 Grand Marquis, Mountaineer This article supersedes TSB 04-17-5 to update the model year and vehicle line coverage. ISSUE Some 2003-2005 Expedition/Navigator, 2004-2005 F-150 vehicles equipped with a 9.75? or 8.8? limited slip rear axle, and 2002-2005 Explorer 4dr, Mountaineer, Crown Victoria, Grand Marquis, Town Car, and Mustang vehicles equipped with 8.8? limited slip rear axle, may exhibit a chatter, shudder, a binding sensation, or a vibration during low speed turns. On 4×4 vehicles, the sensation may appear to be originating from the front axle or the steering gear. ACTION First verify the condition. On 4×4 trucks ensure that the vehicle is in 2WD, to isolate the rear axle. On all vehicles, turn the wheel fully right (or fully left) and then accelerate the vehicle. If the condition is verified to be in the rear axle, replace the limited slip clutch pack. SERVICE PROCEDURE

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.
