Rearend where to add lubricant in rear axle

Other than watch a You Tube Video, on any similar
axle housing ?

Remove the rear cover,bolt,cross shaft pin,push
axles in,remove c-clip & pull axle out !!

Axles usually have a half moon pin at the rear of the axle shaft. They are hard to see. but you can see them and remove them through the rearend spider gear cover.

Hello, there is a fill pluf on the passenger side of rear end to check the fluid level and to add fluid. here is some help on this.

Remove the rear axle fill plug.

Inspect the lubricant level. Specification
The lubricant level should be between 0-10 mm (0-0.4 in) below the fill plug opening.

If the level is low, add lubricant until the level is even with the bottom edge of the fill plug opening

Have the rear-end check out (3rd member) center part of rear-end housing, and your rear axle bearing's, axle bearing if bad can also damage rear axle shaft's and will also have to be replaced.

Schematics for these rear axles are many. I will need the axle code to fetch the correct ones for you. A one ton have 14 different rear axle designs

This amount of play would not be excessive. I don't think you can remove sll the play in a GM rearend. Do you have a posi-track rearend? That could be acting up and creating your problem.

only on right turns?? a smaller tire would have resulted in damage if the rear is a locking type rearend. IF it is a locking rear end I would change the oil, noting the color and how it looks. replace it and add some "slip additive"............. IF its not a locking type axle, maybe a spider gear problem, but thats inside the housing, not out by the wheel. You may need to take the axle out and inspect the axle/ bearing.

Section 05-02A: Axle, Integral Carrier — 8.8-Inch Ring Gear 1994 Town Car, Crown Victoria/Grand Marquis. Workshop Manual REMOVAL AND INSTALLATION Axle Shaft NOTE: Whenever replacing the rear axle lubricant, use Rear Axle Lubricant XY-90-QL (ESP-M2C154-A) or equivalent.
Removal
CAUTION: The rear brake anti-lock sensor must be removed before the axle shafts are removed. The rear brake anti-lock sensor is bolted on the rear disc brake caliper anchor plate.

1. Raise vehicle to desired working height. Refer to Section 00-02 . Remove rear wheel (1007) and tire assembly. Remove rear disc brake calipers (2552) and rear disc brake rotors (2C026) .
   
   
   
   
   

1. Clean all dirt from area of axle housing cover with a wire brush and/or cloth.

1. Drain rear axle lubricant by removing the axle housing cover .

1. Remove differential pinion shaft lock pin and differential pinion shaft .
   
   
   
   

1. Push flanged end of the axle shafts toward the center of the vehicle and remove the rear axle shaft retaining u-washer from the button end of the axle shaft .
   
   
   
   

1. Remove axle shaft from the rear axle housing , being careful not to damage the inner wheel bearing oil seal (1177) and rear brake anti-lock sensor ring.

Installation
NOTE: Check for presence of rear axle shaft o-ring (4A332) on the spline end of the shaft and install if not present.
CAUTION: Care must be taken not to let axle shaft splines damage oil seal or bearing assembly.

1. Carefully slide axle shaft into rear axle housing without damaging rear wheel bearing (1225) or rear brake anti-lock sensor indicator (2C189) . Start splines into side gear and push firmly until the button end of axle shaft can be seen in the differential case .

1. Install the rear axle shaft retaining u-washer on the button end of the axle shaft splines, then pull the shaft outboard until the shaft splines engage and the rear axle shaft retaining u-washer seats in the counterbore of the differential side gear .

1. Position the differential pinion shaft through the differential case and differential pinion gears , aligning the hole in the differential pinion shaft with the lock bolt hole. Apply Rear Axle Lubricant to differential pinion shaft lock pin . Install differential pinion shaft lock pin and tighten to 20-41 Nm (15-30 lb-ft). CAUTION: Differential pinion shaft lock pin must be tightened to specification using Stud and Bearing Mount E0AZ-19554-BA (WSK-M2G349-A1) or equivalent.
   
   
   
   
   NOTE: Axle housing cover must be installed within 15 minutes of application of the silicone rubber or new silicone rubber must be applied.
   CAUTION: Make sure machined surfaces on both axle housing cover and rear axle housing are clean before installing the new silicone sealant. Inside of axle must be covered when cleaning the machined surface to prevent axle contamination. Tighten the cover bolts in a crosswise pattern to ensure uniform draw on axle housing cover .
   

1. Apply Silicone Rubber D6AZ-19562-AA or BA (ESB-M4G92-A or ESE-M4G195-A) or equivalent. Install axle housing cover and tighten retaining bolts to 28-38 Nm (38-52 lb-ft).
   
   
   
   

1. Add Motorcraft Rear Axle Lubricant XY-90-QL or KL (ESP-M2C154-A) or equivalent until it is 6-14mm (1/4-9/16 inch) below bottom of fill hole.

1. Install rear brake anti-lock sensor indicator . Tighten retaining bolt to 4.5-6.8 Nm (40-60 lb-in).

1. Install rear disc brake caliper and rear disc brake rotor .

1. Install wheels and tires.
