Hi Douglas, I'm glad to help. My first suggestion is to get to complete shaft. This way you want have any problems later on. It's not that much more expensive and you'll be glad you did. Below is the procedure for replacing them.
FRONT DRIVESHAFTS
REMOVAL
Raise vehicle on jack stands or centered on a frame contact type hoist. Refer to Hoisting in the Lubrication And Maintenance section of this manual for the required lifting procedure to be used for this vehicle.
Remove the wheel and tire assembly from the vehicle.
Remove the wave washer Wave Washer from the end of the stub axle
CAUTION: Wheel bearing damage will result if after loosening hub nut, vehicle is rolled on the ground or the weight of the vehicle is allowed to be supported by the tires.
With the vehicle's brakes applied to keep hub from turning, loosen and remove the stub axle to hub nut.
Remove the disc brake caliper from the steering knuckle. Caliper is removed by first rotating top of caliper away from steering knuckle and then removing bottom of caliper out from under machined abutment on steering knuckle Brake Caliper Mounting To Steering Knuckle
Support disc brake caliper assembly by using a wire hook and suspending it from the strut assembly Correctly Supported Disc Brake CaliperDo not allow the brake caliper assembly to hang by the brake flex hose.
Remove nut attaching outer tie rod end to steering knuckle Removing Tie Rod End Attaching NutNut is to be removed from tie rod end using the following procedure, hold tie rod end stud with a 11/32 socket while loosening and removing nut with a wrench.
Using a pry bar, separate steering knuckle from ball joint stud Separating Ball Joint Stud From Steering KnuckleNote: Use caution when separating ball joint stud from steering knuckle, so ball joint seal does not get cut.NOTE: Care must be taken not to separate the inner C/V joint during this operation. Do not allow driveshaft to hang by inner C/V joint after removing outer C/V Joint from the hub/bearing assembly in steering knuckle, end of driveshaft must be supported.
Support the outer end of the driveshaft assembly. Insert a pry bar between inner tripod joint and transaxle case Disengaging Inner Tripod Joint From Transaxle Pry against inner tripod joint, until tripod joint retaining snap ring is disengaged from transaxle side gear.
Hold inner tripod joint and interconnecting shaft of driveshaft assembly. Remove inner tripod joint from transaxle, by pulling it straight out of transaxle side gear and transaxle oil seal Tripod Joint Removal from TransaxleWhen removing tripod joint, do not let spline or snap ring drag across sealing lip of the transaxle to tripod joint oil seal.
INSTALLATION
Thoroughly clean spline and oil seal sealing surface, on tripod joint. Lightly lubricate oil seal sealing surface on tripod joint with fresh clean transmission lubricant.
Holding driveshaft assembly by tripod joint and interconnecting shaft, install tripod joint into transaxle side gear as far as possible by hand Tripod Joint Removal from Transaxle
Grasp inner tripod joint an interconnecting shaft. Forcefully push the tripod joint into side gear of transaxle, until snap ring is engaged with transaxle side gear. Test that snap ring is fully engaged with side gear by attempting to remove tripod joint from transaxle by hand. If snap ring is fully engaged with side gear, tripod joint will not be removable by hand.
Clean all debris and moisture out of steering knuckle, in the area were outer C/V joint will be installed into steering knuckle.
Ensure that front of outer C/V joint which fits against the face of the hub and bearing is free of debris and moisture before installing outer C/V joint into hub and bearing assembly Outer C/V Joint Inspection
Slide drive shaft back into front hub and bearing assembly. Then install steering knuckle onto the stud of the ball joint assembly Steering Knuckle Separation From Driveshaft
Install a new steering knuckle to ball joint clamping bolt and nut Control Arm To Steering Knuckle Attachment Tighten the clamping bolt and nut to a torque of 135 N·m (100 ft. lbs.)
Install tie rod end into steering knuckle. Start attaching nut onto stud of tie rod end. While holding stud of tie rod end stationary using a 11/32 socket, Removing Tie Rod End Attaching Nut tighten tie rod end to steering knuckle attaching nut. Then using a crowfoot and 11/32 socket Torquing Tie Rod End Attaching Nut , tighten the tie rod end attaching nut to a torque of 54 N·m (40 ft. lbs.)
Install disc brake caliper assembly on steering knuckle. Caliper is installed by first sliding bottom of caliper under abutment on steering knuckle, and then rotating top of caliper against top abutment Brake Caliper Mounting To Steering Knuckle
Install disc brake caliper assembly to steering knuckle attaching bolts Front Disc Brake Caliper Attaching Bolts Tighten the disc brake caliper assembly attaching bolts to a torque of 22 N·m (195 in. lbs.)
Clean all foreign matter from the threads of the outer C/V joint stub axle. Install the washer and stub axle to hub/bearing assembly nut on stub axle and securely tighten nut.
Install front wheel and tire assembly. Install and tighten the wheel mounting stud nuts in proper sequence until all nuts are torqued to half the required specification. Then repeat the tightening sequence to the full specified torque of 135 N·m (100 ft. lbs.)
Lower vehicle.
With the vehicle's brakes applied to keep hub from turning, tighten the hub nut to a torque of 244 N·m (180 ft. lbs.) Torquing Front Stub Axle To Hub Nut
Install the spring wave washer on the end of the stub axle.
Check for correct fluid level in transaxle assembly. Refer to Group 21, Transaxle for the correct fluid level checking procedure for the type of transaxle being checked.
Set front toe on vehicle to required specification.
The wheel bearings on these vehicles are not adjustable. If the bearings become loose or make noise, they must be replaced.
Removal & Installation
Before servicing the vehicle, refer to the Precautions section.
On 4WD vehicles, remove wheel center cap, if equipped, and the drive axle nut and washer
Raise and support the vehicle.
Remove or disconnect the following:
NOTE
Lay the hub and bearing on the wheel studs on the outboard side. This will avoid damaging the bearing seal.

Place a brass drift against the outer edge of the halfshaft to protect the shaft threads. Use a hammer to sharply strike the brass drift, but to do not remove the halfshaft at this time.Wheel speed sensorWheel hub and bearing-to-steering knuckle bolts and hub and bearing

Lower the vehicle
On 4WD vehicles, install the drive axle nut and tighten to 103 ft. lbs. (140 Nm), then install the center cap.
Here are the front axle nut torque specs for the 2004 Chevy Silverado 2500HD:
• Axle Shaft nut - 177 ft-lb
• hub and bearing assembly to steering knuckle bolts - 133 ft-lb
It's pretty simple.
-Remove the tire
-Install a punch into the fins of the rotor. Rotate the rotor counterclockwise until the punch hits the caliper and remove the axle nut.
- I like to remove the outer tie rod end from the knuckle. This makes it easier to get at the caliper bracket bolts and the wheel hub bolts
- remove the caliper and the rotor
- unplug the abs harness
- remove the three bolts that hold the hub to the knuckle.
- remove the hub/bearing from the knuckle.
The hub may be corroded and frozen a little to the knuckle. Sometimes it can take a bit of hammering to get them to pop.
Also make sure you torque the axle nut to the correct torque spec. Failure to do this will causing the bearing to fail early!
Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
The front wheel bearing is a hub and bearing assembly. To remove you will....
1. Remove the tire
2. Remove the axle nut. You can put a punch in the fins of the rotor to keep the assembly from turning while you rmove the nut. You can can do the same thing when you torque the axle nut.
3. Remove the caliper and rotor.
4. Unplug the abs sensor if equipped.
5. Remove the three bolts that hold the hub to the knuckle.
6. Rmove the hub.
If you need torque specs let me know and i'll get them for you. It is absolutely critical that you torque the axle nut to the proper spec!
