Remove the remainder of the cover bolts and store them in a plastic container then they don't go lost. If gear oil doesn't showtime to leak you should help pause the seal loose by using a apartment bract (standard) screwdriver and allow the gear oil to drain out. Once most of the gear oil has tuckered into the grab basin, remove the remaining iii bolts to remove the cover. Utilise a large screw commuter to continue releasing the seal. Keep to remove the embrace and place information technology off to the side. This encompass will need to be cleaned which will exist done in later steps. Once the cover is removed information technology will expose the inner workings of the differential. SPONSORED LINKS Locate and Remove Pivot Pin Commodities After inspecting the inner workings and while the transmission is in natural, rotate the driveshaft until the carrier pivot shaft bolt is exposed. This can take a few turns of the driveshaft earlier seeing it. Stop turning when the bolt is near the height of housing. Likewise, keep your fingers clear while rotating the gear prepare to avert injury, these gears can be sharp. Once the carrier bolt has been located, use a small-scale ratchet or wrench (8mm) to loosen and remove the commodities. This bolt tin exist snug and so brand sure your tool is squarely on the head of the bolt to avoid rounding which will make the chore much more than difficult. If the bolt breaks inside the carrier use an air hammer which can be used to force outward (break downwardly) the pivot rod through the carrier.

Remove the C Clip and Axle After the pinion pin has been removed, once again rotate the driveshaft until the "C" clip access port appears. Sentry the unit as you slowly turn it, if the spider gears (small gears) start to motility into the port then plough the axle with the driveshaft to go on the gears in their position. SPONSORED LINKS Next, at the axle flange (wheel side) push the axle inward toward the differential, the axle volition motion inward slightly. This is to allow enough clearance for the "C" clip to be removed which holds the axle into the differential. Using a small screwdriver or magnet piece of work the metal "C" clip in a round motion, This will enable you to remove the clip which volition release the beam from the differential. This can accept a little fourth dimension so hang in in that location. One time the C clip has been removed from the carrier bank check the clip for wear and scoring and supervene upon if needed. This will be a dealer part. Now that the C clip has been removed grasp the beam at the flange and pull outward, the axle should slide out completely from the differential housing, use a shop towel around the axle every bit information technology's being removed to wipe residual gear oil to keep the mess downwardly to a minimum. SPONSORED LINKS In this picture the parking brake shoes have been removed for replacement simply if the shoes are okay yous tin leave them installed while replacing the bearing and seal. After the beam has been removed inspect the begetting and seal surface to check for wearable and scoring and supersede if damaged.

You can use a large punch and piece of work around the begetting to install it, just using the tool is the preferred method. Set the new bearing squarely into the differential housing, then use the tool to install the bearing using a hammer. One time the bearing is fully installed the hammer will have a hard clunk audio and the bearing will non motility inward. This is signaling the bearing is completely confronting the house shoulder. Install the Beam Seal SPONSORED LINKS Once the bearing has been installed the seal is next. Inspect the seal surface for grooves or scores.

These seals have a outer lip and then the seal tin can simply exist installed ane mode. The seals should look identical unless they have been updated past the manufacturer. SPONSORED LINKS One time the surface has been cleaned, match the new seal to the former unit of measurement and use sealer to the differential housing if needed. Virtually seals have a sealer allied to them as a thin coating, this seal uses an orange colored sealer. Next, y'all can use the seal installer which is one and the same to the bearing installer but we thought nosotros would evidence you how nosotros did it in the former days in this case. Set and concord the seal in place, then bulldoze the seal into the differential housing using a apartment bar to hammer against while installing the seal. Continue this functioning until completely installed and flush against the housing and seal lip. Reinstall the Axle SPONSORED LINKS Afterwards inspecting the axle for damage and yous run into that it's okay to reinstall, utilise a modest amount of gear oil to the bearing and seal.

Also, plow the beam slightly at the same time, this will permit the axle spline to engage into the carrier. Then proceed to push the beam inward until it stops. Next, check to run into if the beam has been fully engaged into the carrier enough to put the clip into place.

Make certain this surface is clean from gear oil or it will contaminate the sealer and possibly cause a leak. Use a shop towel to wipe out the inner differential housing to help command additional oil. Next, clean the metal debris from the differential cover magnet and continue to clean the gasket surface with the scraper until free from gear oil. Apply carburetor cleaner to ensure no oil is present. Then, install the new gasket using silicone rubber as a sealer. Create bead inside of the bolt holes to help command leaks. Do non use cheap home grade sealer, y'all need to go the skilful stuff which costs a little more than only is bachelor from Amazon, Dwelling house Depot or Lowes hardware stores. Advisedly install the differential encompass every bit non to disturb the gasket location on the encompass. Excessive movement will cause the sealant to exist less constructive.

As well tight will spilt the gasket while to loose will let a leak, it's an art learned like anything else. Refill with Gear Oil Once the embrace bolts are tight, remove the differential make full plug which is located nearly the driveshaft this will be a 3/viii drive socket extension or ratchet head. Then install the gear oil, if your vehicle has the clutch manner (limited slip) unit you volition need to pour in an additive which helps lubricate the clutches.
