Do you have a diagram of the front wheel assembly for a 2004 Hyundai Santa Fe that you could share?

Is this what you are looking for?

Thank you for these diagrams. Looking for a diagram on replacing the front left wheel bearing. Would you happen to have that?
Also, saw a post that someone disconnected the rear differential and now runs fine in front wheel drive. Do you see this as an issue and can/should this be done? If so, how?

FRONT HUB/KNUCKLE
COMPONENTS
Fig. 35: Front Hub/Knuckle Components

1. Raise the vehicle and remove the front wheel.

2. Remove the wheel speed sensor from the knuckle.

3. Remove the brake caliper and suspend it with a wire.

4. Remove the split pin, the castle nut and the washer from the front hub.

5. Remove the strut and the two bolts mounting the knuckle.

6. Disconnect the tie rod end ball joint from the knuckle using the special tool (09568-34000).

7. Remove the lower arm ball joint mounting bolt.

8. Using a plastic hammer, drive out the axle hub from the driveshaft.

9. Remove the front axle assembly.

DISASSEMBLY

1. Remove the brake disc from the hub.

2. Remove the snap ring.
Fig. 42: Removing Snap Ring

3. Remove the hub from the knuckle using the special tools (09517-21500, 09517-3A000, 09517-29000).

Install the special tool to the hub and knuckle.
Tighten the nut of the special tool to disconnect the hub from the knuckle.

4. Using the special tools (09455-21000, 09545-34100), remove the wheel bearing inner race from the hub.

5. Using the special tools (09532-32000, 09216-22100), remove the wheel bearing outer race from the knuckle.

REASSEMBLY
1. Apply a thin coat of multi-purpose grease to the surface of the knuckle and bearing.

2. Using the special tool, press the bearing onto the knuckle.

Press-in load [kg(f), (lb(f))] : 4500 5000 (9921 11023)

NOTE: Do not press against the outer race of the wheel bearing
because that can cause damage to the bearing assembly.

Always use a new bearing assembly.

3. Install the snap ring into the groove of the knuckle.

4. Install the backing plate to the knuckle.

5. Press the hub onto the knuckle using a special tool.

Press-in load [kg(f), (lb(f))] : 2000 2500(4409 5512)

NOTE: Do not press against the outer race of the wheel bearing because this can cause damage to the bearing assembly.

6. Rotate the hub several times while seating the bearing.

7. Install the disc to the hub.

4Wheel drive System Description

1. The transfer case is a full-time four-wheel drive system developed for stable driving in the worst conditions. It improves not only driving safety on a normal road but also the performance of the vehicle in a slippery road by distributing the power to both, front and rear wheels.

2. A driver may not control front or rear wheel drive directly like a four-wheel drive vehicle.

3. When the front or rear wheels slip, the viscous generates the effect of differential limitation made by viscosity torque of silicon oil inside the viscous coupling, caused by relative revolution difference among interior plates.

4. This system secures optimum drive performance and vehicle safety according to a road by transmitting viscous torque to the side there is a little slippage between front wheels and rear wheels.

5. Rear wheel power set by the above system is transmitted to the rear wheel through the hypoid gear.

Above are the description of the 4WD functions and by disconnecting the rear differentials, you would be diabling the functions and the 4WD ECU would flash to indicate trouble codes intermittently.

If vehicle is used for normal driving without any extreme conditions, disconnecting the rear differentials would not have any adverse effects.

To disconnect the rear differentals, removing the propellershaft is all you need to do.

Thank you for this information. Regarding the disconnecting the rear differentials, would there be a way to place a switch inside the vehicle to enable/disable the AWD? If so, can you give me some advise on how the switch would need to be connected (wired)? What are the best options if this is possible?

AWD are full time all wheel drives and cannot be turned on or off. Only 4WD can.

Correct that the AWD can be disabled as you previously mentioned? By disconnecting the rear differentials? (To disconnect the rear differentals, removing the propellershaft is all you need to do.) Thank you.

Some vehicles can but not all and I am not sure if your vehicle can be done. The information in our database are not comprehensive so I am not able to comment on that.

If you wish to know, then you can try disconnecting the propeller shaft and see if it works.
