Hi it sounds as if your brake linings have broken away you will need to remove the drum to see.

Special Tools

• Slide Hammer
• Axle Remover

Removal Procedure

1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation.
3. Remove the brake caliper. Refer to Rear Brake Caliper Replacement.
4. Remove the rear wheel speed sensor. Refer to Rear Wheel Speed Sensor Replacement.
5. Remove the rear axle housing cover and the gasket. Refer to Rear Axle Housing Cover and Gasket Replacement.
6. Remove the pinion shaft locking bolt.


7. On axles without a locking differential, remove the pinion shaft.


8. On axles with a locking differential, remove the shaft part way. Rotate the case until the pinion shaft touches the housing.


9. On axles with a locking differential, use a screwdriver, or a similar tool, in order to enter the differential case and rotate the C-lock?(1) until the C-lock aligns with the thrust block?(2).
10. Push the flange of the axle shaft?(1) toward the differential.


11. Remove the C-lock from the button end of the axle shaft.

Note: When removing the axle shaft, do not rotate the shaft. Rotating the shaft will misalign the gears. Misaligning the gears will make the installing of the axle shaft difficult.
12. Remove the axle shaft from the housing.
13. Hope this helps?

there is a proportioning valve to the rear brakes that only allows them to operate fully under load or heavy braking. If it is faulty then full brakes will be applied to the rear which will allow them to lock up first.
Check pad/shoe condition and rear drum/shoe adjustment as well

check the wiring to the retarder and retarder controls ( accelerator sensor --brake sensor etc ) finally have the unit inspected by a service centre dealer.

Hub & Bearings

Adjustment
Check the backlash in bearing shaft direction and the axle hub deviation. Maximum for backlash should be 0.0020 in. (0.05mm) and for axle hub deviation 0.020 in. (0.05mm).

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. Insert Rear Bearing Remover T85L-1225-AH in bore and position it behind bearing so tangs on tool engage bearing outer race. Remove rear wheel bearing and inner wheel bearing oil seal as a unit, using Impact Slide Hammer T50T-100-A.
   
   Rear Disc Brake Caliper Anchor Plate
   
   
   
   
   

1. Lubricate the rear wheel bearing with Rear Axle Lubricant.
   
   
   
   

1. Install rear wheel bearing into the housing bore using Axle Tube Bearing Replacer T78P-1225-A.
   
   
   
   CAUTION: Installation of rear wheel bearing or inner wheel bearing oil seal assembly without proper tool may result in an early bearing or seal failure. If inner wheel bearing oil seal becomes cocked in bore during installation, remove it and install a new one.
   

1. Install the inner wheel bearing oil seal using Axle Tube Seal Replacer T78P-1177-A. Use Premium Long-Life Grease XG-1-C or K (ESA-M1C75-B) or equivalent between the lips of the inner wheel bearing oil seal .
   
   
   
   

1. Install axle shafts as outlined.

The adjuster is just like on a car with drum brakes. It can be adjusted with the wheels still on the truck, but if yours is out enough that it doesn't work, an inspection is warranted. Axle seal failure is common and will soak the shoes.

Jacked both rear wheels off ground, and while slowly spinning wheel, tighten the star-wheel adjuster until you just hear and feel brake drums rubbing, then loosened slightly.
There's a plastic dust cover about 1/4" X 1" that you remove, and use a drum brake adjuster tool.

The driverside access hole is below axle, easily accessable. To tighten driver side rear parking brake, turn star-wheel adjuster down.


The passengerside access hole is found above axle, and difficult to see. Removed pass side wheel and used an inspection mirror.
To tighten passenger side rear parking brake, turn star-wheel adjuster up.

Good luck and hope this helps. Oh and the other thing to is that if you do smell axle fluid around the wheels and see oil leaking from the drum area. Then you have a axle wheel seal and or bearing gone bad too.
