How do I replace the inner and outer bearings on a rear axle of a 2006 Chevy Colorado, and adjust the endplay so it doesn't whine anymore? The truck has had a hard life so far, carrying 2000 lbs daily, and only did 70000 miles.

Yes, Undo the 32mm nut, first.
And, don't get the bearings dirty with dust from the brake drums, or , if you do, replace the inner and outer bearings with new greased up ones.REAR DRUM BRAKES Brake Drums REMOVAL & INSTALLATION CAUTION Brake linings contain asbestos. Asbestos is a known cancer-causing agent. When working on brakes, remember that the dust which accumulates on the brake parts and/or in the drum contains asbestos. Always wear a protective face covering, such as a painter's mask, when working on the brakes. NEVER blow the dust from the brakes or drum.
Raise the vehicle and support safely.
Remove the wheel and tire assembly.
On vehicles without rear bearing hub, remove the dust cap, cotter pin, nut lock, wheel bearing nut and washer from the spindle. Remove the outer wheel bearing. Remove the drum with the inner wheel bearing from the spindle. If the drum is difficult to remove, remove the plug from the rear of the backing plate and push the self adjuster lever away from the star wheel. Rotate the star wheel to retract the shoes. Remove the grease seal.
If equipped with a rear bearing hub, remove the drum by removing the retainer screws from the drum and pulling the drum from the hub assembly. If the drum is difficult to remove, remove the plug from the rear of the backing plate and push the self adjuster lever away from the star wheel. Rotate the star wheel to retract the shoes.
On vehicles equipped without rear bearing hub, lubricate and install the inner wheel bearing. Install a new grease seal. Install the drum to the spindle. Lubricate and install the outer wheel bearing, washer and nut. Adjust the bearing preload following the procedure outlined in the "Rear Wheel Bearing'' of this section. When the bearing preload is properly set, install the nut lock and a new cotter pin. Install the grease cap.
On vehicles with rear bearing hub, install the brake drum to the hub assembly and install the retaining screws.
Install the wheel and tire assembly. Adjust the rear brakes as required.
Apply the brakes until a firm pedal is obtained, prior to moving the vehicle.
Axle and bearing issues can be hard to pinpoint. I assume you mean they replaced the outer bearings. There are still inner bearings called carrier bearings as well as an inner and outer pinion bearing.
I would take it back and tell them they have not fixed it right yet.

REMOVAL AND INSTALLATION
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.
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) .
Clean all dirt from area of axle housing cover with a wire brush and/or cloth.
Drain rear axle lubricant by removing the axle housing cover .
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 .
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.
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 .
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 .
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 .
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).

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