The other guys have never taken the wheel bearings out of a 2007 Tacoma! Remove the tire (duh) Remove the 12mm bolt holding the brake line securing bracket Un-clip the air sensor hose clip Remove the two 17mm bolts holding the brake assembly on the back side Remove the rotor from the wheel "spindle"- slides right off. Unscrew the four metric bolts (maybe 17mm) holding the wheel housing to its mount (they cannot be removed from the assembly yet, see below). That's right there is no normal wheel spindle with a big nut on the end of a threaded shaft in the middle! The wheel mounting plate (with the 6 studs) is pressed into the bearing housing. Get a replacement bearing assembly and take it and your old unit to a machine shop (unless you have a good press). An easy job, just expensive- $140 for the bearing assembly.
The front wheel bearings on your Dodge Dakota allow the wheels to spin freely on the axle spindle. These sealed bearings may cause noise once they wear out, develop a pit on the races, bends and other damage that interfere with wheel performance. However, the front bearings form a single assembly with the wheel hubs and they should be replaced as a single unit. Fortunately, installing a new assembly is not a difficult process.
Removing the Hub/Bearing Assembly
Before raising the front wheel(s), loosen the half shaft nut using an axle nut socket. Then remove the wheel/tire assembly and the half shaft nut. If your particular Dakota model comes equipped with an Anti-lock Bake System (ABS) sensor, remove the sensor form its bracket and move it aside.
Now you are ready to remove the brake caliper and rotor. Make sure to secure the caliper to the coil spring using a piece of heavy wire. Do not let it hanging by the brake line to avoid damage to the brake hose attached to the caliper. With the caliper and rotor out of the way, you have access to the hub/bearing assembly mounting bolts.
On some models, you can only access the hub/bearing mounting bolts through the holes in front of the hub/bearing assembly. Rotate the assembly by hand as you loosen and remove the mounting bolts. Once you remove the bolts, you can detach the hub/bearing from the steering knuckle and halfshaft. If the bearing assembly seems stuck to the halfshaft, use a 3 jaw gear puller to remove it.
About an hour a side...This is the whole job and pictures....
The hub and wheel bearing unit is serviced as a complete assembly. Replacement of the front drive hub and bearing assembly can be done without having to remove the steering knuckle from the vehicle. However, if the hub/bearing assembly is frozen to the steering knuckle, removal of the steering knuckle is required.
Disconnect the negative battery cable.
Remove the cotter pin from the end of the stub axle. Remove the nut lock and spring washer. With the brakes applied, loosen, but do NOT remove the axle nut and washer with the vehicle still on the ground or damage to the wheel bearing will result.
Raise and safely support the vehicle. Remove the wheel.
Remove the front brake caliper assembly from the steering knuckle assembly and support from the strut assembly using a strong piece of wire.
Remove the front brake rotor from the hub/bearing assembly.
Remove the retaining nut and washer from the halfshaft stub axle.
Remove the ABS wheel speed sensor from the steering knuckle.
Remove the 4 hub and bearing assembly mounting bolts from behind the steering knuckle.
Remove the hub and bearing assembly from the steering knuckle.
Thoroughly clean the mating surfaces of the steering knuckle and the hub and bearing assembly of any foreign material or nicks so the surfaces are clean and smooth.
Install the new hub and bearing assembly and tighten the mounting bolts in a crisscross pattern to 45 ft. lbs. (65 Nm). Be sure the hub and bearing assembly is seated squarely against the front steering knuckle.
Install the disc brake rotor.
Install the brake caliper assembly onto the steering knuckle.
Install the axle washer and nut. Tighten but do not torque.
Install the ABS wheel speed sensor.
Install the wheel and lug nuts. Torque the lug nuts, in sequence, to 95 ft. lbs. (129 Nm).
Lower the vehicle. Do NOT roll the vehicle until the axle nut has been properly torqued or damage to the front wheel bearings will result.
With the vehicle's brakes applied, torque the axle nut to 180 ft. lbs. (244 Nm). Install the spring washer, nut lock and a new cotter pin. Wrap the cotter pin prongs tightly around the axle nut lock.
Reconnect the negative battery cable. Check the wheel alignment.
The hub/bearing assembly is attached to the steering knuckle with four bolts
Removing a hub/bearing assembly
If the hub/bearing is "frozen" to the steering knuckle, separate the ball joint and lightly tap on the hub/bearing from behind
The hub/bearing assembly should free itself from the steering knuckle
Replacing the front wheel bearing/hubs can be a big job for the inexperianced. Briefly...
Remove brake caliper assembly, do not remove brake line.
Remove caliper bracket.
Remove brake rotor.
Unplug ABS sensor.
Remove the large axle nut.
Press axle out of bearing (may need special tool)
Remove the 3 bearing bolts and remove bearing.

its actually pretty easy if you have the basic tools needed and a little mechanical knowledge, because i dont think you can buy just the bearing at a auto parts store. they sell you the whole hub assembly which is great for the DIYer.
lift the car off the ground and block it from rolling and place a jack stand under it so it cant fall on anyone.
vehicles are equipped with sealed hub and bearing assemblies. The hub
and bearing assemblies are non-serviceable. If the assembly is damaged,
the complete unit must be replaced.
Before servicing the vehicle, refer to the precautions section.

(95 Nm).Anti-lock Brake System (ABS) connector, if equippedBrake rotorCaliper onto the steering knuckle. Torque the bolts to 38 ft. lbs. (51 Nm).Halfshaft nut. Torque the hub nut to 284 ft. lbs. (385 Nm) on nuts colored black, or 173 ft. lbs. (235 Nm) on gray colored nuts.Front wheel. Torque the nuts to 100 ft. lbs. (140 Nm).
Remove the steering knuckle assembly, as described previously.
Remove the bolts attaching the hub/bearing assembly to the steering knuckle.
the hub/bearing assembly from the front of the steering knuckle. The
bolt-in front wheel bearing used on the vehicle is transferable to a
replacement steering knuckle, if the bearing is in serviceable
condition. If the bearing will not come out of the steering knuckle, it
can be tapped out using a soft-faced hammer.
Thoroughly clean all parts, including the hub/bearing assembly mounting surfaces on the steering knuckle.
the replacement hub/bearing assembly onto the steering knuckle,
aligning the bolt holes of the bearing flange to the knuckle.
the attaching bolts and tighten evenly to make sure the bearing is
square to the face of the steering knuckle. Tighten the attaching bolts
to 80 ft. lbs. (110 Nm) on Cirrus, Stratus, Sebring convertible and
Breeze, or 65 ft. lbs. (88 Nm) on Sebring coupe and Avenger.
Install the steering knuckle assembly, as previously described.
