Axle Vent
NOTE: If the vent cannot be cleared, it must be installed new.
A plugged vent will cause excessive seal lip wear due to internal pressure buildup. If a leak occurs, check the vent. Make sure the vent hose is not kinked. Remove the hose from the vent nipple and clear the hose of any foreign material. While the hose is removed, pass a length of mechanics wire or a small diameter Allen wrench in and out of the vent to clean it. Connect the hose when done. The vent is located on the drivers side top of axle housing.
If you plan on doing most repairs yourself I would suggest buying a Haynes or Chilton manual for your particular vehicle. Or there are some data disks on e.bay($12-$15) For a cost of under $25, you can almost do any repair yourself with these manuals.Also there are online manuals like the site called ALLDATA where guides can be viewed for a fee. All these solutions will save you time and money, and give peace of mind over correct repairs. I can post you some procedures here also.
- CAUTION: Do not use heat to loosen a seized lug nut. Heat can damage the wheel (1007) and the rear wheel bearings (1225).
- Loosen the lug nuts (1012).
- Remove the center cap.
- With the weight of the vehicle on the wheels, loosen the lug nuts
Raise and support the vehicle. .Remove the wheel and tire assembly.
-
Remove the lug nuts.
-
Remove the wheel and tire assembly. Remove the axle housing cover (4033).
- Loosen the axle housing cover bolts (4346) and drain the rear axle (4001).
- Remove the axle housing cover bolts.
- Remove the axle housing cover.
7.Remove the rear disc brake rotors You will have to remove the brake caliper to get rotor off.
8.
CAUTION: Once the differential pinion shaft (4211) has been removed, turning the differential case (4204) or an axle shaft (4234) will cause the differential pinion gears (4215) to fall out of the assembly. This could result in chipped or damaged components.
9.
1.Remove the differential pinion shaft lock bolt. 2.Remove the differential pinion shaft.
10.
CAUTION: Do not damage the rubber O-rings in the U-washer grooves. Remove the U-washers (4N237).
- Push the axle shafts inboard.
- Remove the U-washers.
11.Reinstall the differential pinion shaft.
- Install the differential pinion shaft.
- Install the differential pinion shaft lock bolt finger-tight.
12.CAUTION: Do not damage the inner wheel bearing oil seal (1177). Remove the two axle shafts.
CAUTION: Never remove the axle shaft oil seal by itself. Always remove the rear wheel bearing and the axle shaft oil seal at the same time. NOTE: If the axle shaft oil seal is leaking, the axle housing vent may be plugged with debris. Use Impact Slide Hammer and Axle Wheel Bearing Puller to remove the rear wheel bearing and the axle shaft oil seal.

Install the rear disc brake rotors; Install the axle housing cover and fill the rear axle housing (4010) with 2.4 liters (5.5 pints) of specified lubricant
WARNING: Always remove any corrosion, dirt or foreign material that may be present on the mounting surfaces of the wheel or the surface of the wheel hub or rear disc brake rotor that contacts the wheel. Installing wheels without proper metal-to-metal contact at the wheel mounting surfaces can cause the lug nut to loosen and the wheel to come off while the vehicle is in motion, causing loss of control. Clean the wheel hub and mounting surfaces. Install the tire and wheel assembly.
Position the tire and wheel assembly. Install the lug nuts and lower the vehicle. Tighten the lug nuts. Install the center cap.
