What is torque specification for rear end differential cover bolt

The general torque spec is 25-30 ft-lbs for the cover bolts for a GM 10 bolt rear axle.

To install the rear pinion shaft on a 2019 Ford F-150, you will need to follow the steps outlined below:

1. First, make sure that the vehicle is supported securely on a lift or jack stands.
2. Remove the rear differential cover and drain the oil.
3. Remove the driveshaft and the axles.
4. Unbolt the pinion flange from the pinion shaft.
5. Remove the pinion nut and the crush sleeve from the pinion shaft.
6. Remove the old pinion shaft and replace it with the new one.
7. Reinstall the crush sleeve on the pinion shaft and install the pinion nut.
8. Tighten the pinion nut to the specified torque using a torque wrench. The torque specifications for the pinion nut will vary depending on the specific model of your Ford F-150.
9. Reinstall the driveshaft and the axles, and refill the differential with oil.
10. Finally, install the rear differential cover.

To set the inch lb setting on the pinion nut, you will need to use a torque wrench that is capable of measuring in inch lbs. To do this, first set the torque wrench to the desired inch lb setting and then tighten the pinion nut until the wrench clicks to indicate that the desired torque has been reached.
The final torque on the pinion nut will depend on the specific model of your Ford F-150 and the torque specifications provided by the manufacturer. It is important to follow the manufacturer's torque specifications to ensure that the pinion nut is tightened correctly and to prevent damage to the vehicle.

If you have the "10 Bolt" rear end (10 bolts hold the rear cover on)

Bearing caps are torqued to 60 lbs/ft
ring gear 90 lbs/ft
Lock tabs 20 lbs ft

If you have the 14 bolt
Bearing caps are torqued to 135 lbs feet
Ring gear 120 lbs/ft

Lock tabs 20 lbs ft.

put flat pan under the housing remove the bolts holding the cover usually 10 or 12 (1/2 or #12 metric) bolts? allow the rear end grease to drain... then scape off the old gasket clean with brake cleaner spray install either new gasket or form one with oil resistant silicone put the cover back on , dont refill the fliud for at least 12 hours if using silicone. Also check the front driveshaft rear end yoke seal....they sometimes leak making the illusion of a rear end pan cover leak...if that is leaking you remove the shaft carefully...remove the large yoke retaining nut, replace the press in seal...be sure retaining yoke nut is properly torqued when reinstalling .

There should be a filler plug on top of the diff housing, it will have a square recess that will accept a 3/8" drive extension for removal.

Block the front tires. Break the rear lugs loose. Jack up the rear of the truck at the center if possible. remove the wheels & brake drums. Remove the brake shoes,return springs & all the other hardware. Remove the differential cover & drain oil. If you have a posi the next step sucks. You need to remove the threaded pin from the housing & remove the axle retaining clips. All the while,being carefull of the spring in the posi unit. If no posi,then same procedure,minus the "pucker factor". After the axle is out,take a large flat blade screw driver or pry bar & pop the seal out. Keep in mind the axle bearing is probably gone too , so that's another procedure. Keep it apart,you'll be glad you did.

Gear lube is SAE 75W-90 GL-5 gear lubricant. If you have a limited slip diff, add 4 oz of limited slip additive.
Torque cover to 15-20 ft-lbs.
