The job starts with raising and supporting the vehicle when swapping out the rear axle housing cover and gasket on a 10.5 inch axle. Make sure to get rid of the old axle housing cover bolts, discard them, and replace with fresh ones only. Carefully remove the bolts, cover, and gasket, and get rid of any gasket bits from the rear axle housing or the cover. Following that, put the axle housing cover and gasket onto the rear axle, and fasten the new bolts until they're tightened to 40 n.m or 30 lb ft. When you have finished tightening the bolts, fill the rear drive axle with fluid and take away the support before lowering the vehicle.

The first step to replace rear axle housing cover and gasket begins with supporting and lifting the vehicle. The procedure requires removing the Drain Plug of 9.5 inch ld and 9.5 inch hd axles or gently loosening the bolts of 8.6 inch axles before draining the rear axle. You must first take out the bolts from the rear axle cover followed by removing the axle housing cover together with its gasket . The axle housing gasket can be reused after installation unless it shows signs of damage. Start by installing the gasket before placing on the axle housing cover . Fitting the mounting bolts requires a torque of 40 n.m (30 lb ft) to tighten. To install the Drain Plug of the 9.5 inch axle confidently tighten it to 33 n.m (24 lb in). Add the fluid into the rear axle until it reaches the level 0-13 mm (0-0.50 inch) below the fill plug opening. Use appropriate fluid to fill the lubricant until it reaches the bottom of the fill plug opening when the fluid level appears low. Finally, lower the vehicle.

The replacement process of the rear axle housing cover and gasket begins with lifting the vehicle and draining the axle lubricant. Work slowly while removing the rear axle housing cover because contact with the gasket must be avoided to prevent any damage that could harm the sealing ability. Transfer the lubricating fluid from the axle through an appropriate container. The inspection of your rear axle cover gasket must determine if nicks, cuts or any damage exists that would prevent proper sealing so you should obtain a new gasket if needed. Preparation of the gasket requires cleaning with suitable cleaner while gasket surfaces of both rear axle housing cover and housing should also get cleaned before installation. Position first the rear axle housing cover gasket and then fit the rear axle housing cover . The rear axle housing cover bolts should be installed using a crosswise pattern while tightening them to 30 Nm (20 ft. lbs.). As the final step use the correct axle lubricant to fill the rear axle before lowering the vehicle.

In order to replace the rear axle housing cover and gasket first; lift the vehicle and drain the rear axle according to the car's circumstances for the particular axle (8.6 Inch Axle, 9.5 Inch LD Axle, 10.5 Inch Axle). Then, come off the rear axle housing cover bolts and throw them away, after which you take off the rear axle housing cover catching the oil in a drain and taking off any gasket material from the rear axle housing and the cover. When installing, mount the new gasket and the rear axle housing cover on the axle housing while not reusing the rear axle housing cover bolts. Apply the new rear axle housing cover bolts and tighten them in a crosswise manner using a wrench to 40 n.m (30 lb ft). Lastly, put in the correct fluid into the rear axle, and drop the vehicle.

Before starting the replacement process of the rear axle housing cover and gasket users should perform the following steps: first raise the vehicle, drain the rear axle and remove all rear axle housing cover bolts. Secure the vehicle at an elevated position then carefully uninstall the rear axle housing cover bolts without causing any harm to the gasket. Place the rear axle housing cover aside before draining the axle lubrication through a proper storage container. The rear axle cover gasket requires immediate replacement if signs of nicks, cuts or damage impair its ability to seal properly. Thus, inspect this gasket before moving forward. You can use a suitable cleaner on reusable gaskets while you also clean the gasket surfaces attached to both the rear axle housing cover and the rear axle housing. After applying the rear axle housing cover gasket install the rear axle housing cover onto the housing. Among the rear axle housing cover bolts install all bolts then tighten them through a crosswise pattern to 30 nm (20 ft. Lbs.). The proper axle lubricant should be added to the rear axle before the vehicle can be thoroughly lowered.

Start by raising the vehicle and draining the rear axle prior to replacing the rear axle housing cover and gasket on an 8.0/8.6 inch axle. Use care when removing the rear axle housing cover bolts so the gasket remains intact before extracting the rear axle housing cover while draining the axle lubricant into a proper container. Check the entire rear axle cover gasket surface for any sign of damage before proceeding. Replace the damaged gasket right away or substitute it with a new one. Reusable gaskets require cleaning using acceptable products and the rear axle housing cover along with housing gasket surfaces need cleanup before installation. Set the rear axle housing cover gasket in position along with placing the rear axle housing cover as you fasten the rear axle housing cover bolts . Use a crosswise pattern when tightening the bolts on 8.0 inch axle to 30 N.m (20 lb ft) and use the same pattern for 8.6 inch axle bolts at 25 N.m (18 lb ft). The correct axle lubricant must be added to the rear axle before performing a vehicle lowering procedure.

A proper replacement of the rear axle housing cover and gasket begins when the vehicle reaches a raised height with the draining of rear axle fluid. Untighten the back cover bolts then detach the rear axle housing cover maintaining constant attention to the rear axle housing cover gasket. Pump the axle lubricant from the system into an appropriate receptacle. Check the rear axle cover gasket for any damage which could lead to ineffective sealing before deciding whether to replace or use it again. A suitable cleaner should be used to clean both the cover gasket and adjacent surfaces from the rear axle housing cover and rear axle housing. Secure the rear axle housing cover gasket while placing the rear axle housing cover into position and tighten the rear axle housing cover bolts in place. When installing the cover bolts in both 8.0 inch and 8.6 inch axles, a crosswise pattern should be used followed by torquing at 30 Nm (20 ft. lbs.) for the 8.0 inch axle and 25 Nm (18 ft. lbs.) for the 8.6 inch axle. The last step includes adding correct axle lubricant to the rear axle followed by lowering the vehicle.

A mechanic should drain the rear axle after lifting the vehicle to undertake a replacement of both the 8.0/8.6 inch axle housing cover and gasket. Use torx tools to carefully remove the rear axle housing cover bolts without damaging the seal. Then remove the rear axle housing cover and save the axle lubricant in a proper receptacle. Examine the rear axle cover gasket for signs of cuts, damage and nicks. Replace the gasket because of any detection of problems. For reuseable gaskets use appropriate cleaning solution to clean surfaces while simultaneously treating both the rear axle housing cover and rear axle housing with proper cleaning methods. Follow fastener precautions when installing both the rear axle housing cover gasket and rear axle housing cover . When installing the rear axle housing cover bolts apply a cross pattern torque sequence at 30 Nm (20 lb ft) for 8.0 inch axles or 25 Nm (18 lb ft) for 8.6 inch axle units. After completing the lubrication process you should lower the vehicle.
