Re: front wheel bearing
There is a tool you can use to remove the old bearing and press in the new one with the spindle still on the car. Here's a link to the procedure:
The tool is called a Hub Shark. It looks like a pain to use it, but I know from experience that dealing with the pinch bolt is much more of a pain. This is the only way to do it that I know of that doesn't involve removing the pinch bolt. It may be easier than it looks but it appears that it'll be an annoyance trying to work around in the wheelwell.

According to Autozone.com, you must replace the whole control arm. Here is their procedure: NOTE
do not begin the removal procedure unless a new strut-to-lower arm nut, a new ball joint pinch bolt/nut and a new lower arm-to-front subframe bolt/nut are available.
Remove or disconnect the following:
Do not use a hammer to separate the ball joint from the front wheel hub and spindle.
WheelsLower arm strut nut and dished washer. Discard them.
Place the steering wheel in the unlocked position.
Do not allow the halfshaft to move outward. Over-extension of the halfshaft joint could result in separation of internal parts, causing failure of the halfshaft joint.
Remove or disconnect the following:
Use extreme care to not damage the ball joint boot seal.
Lower arm ball joint nut and pinch bolt. Discard them.Lower arm from the front wheel knuckle
Remove and discard the lower arm-to-front subframe bolt and nutRemove the lower arm from the vehicleTo install:
Install or connect the following:
Lower arm strut into the lower arm rear strut bushingLower arm into the front sub-frame bracketNew lower arm-to-front subframe nut and bolt. While holding the lower arm horizontal, tighten to 85-97 ft. lbs. (115-132 Nm).Ball joint stud-to-wheel hub and spindle, making sure that the ball stud groove is properly positioned.New lower arm ball joint pinch bolt and nut. Tighten to 46-52 ft. lbs. 62-71 Nm).
Clean the lower arm strut threads to remove dirt and contamination.
Install the dished washer with the dished side away from the lower arm rear strut bushing.
Install the front suspension lower arm strut-to-strut nut and tighten to 85-97 ft. lbs. (115-142 Nm).
remove caliper, rotor, caliper bracket, lower ball joint shaft and two strut bolts. remove bearing housing and any snap rings. remove old bearing. replace and repeat in reverse. watch the abs sensor! costly if damaged. This is not for beginners...
The bearing is in the hub.. Here are some instructions for that:
The wheel bearing is installed in the wheel hub assembly and is serviced by replacement only.
You may need Torx sockets to remove the bearing assembly bolts.
Raise and support the front of the vehicle safely using jackstands.
Remove the tire and wheel assembly.
At the wheel hub, remove the cotter pin and retainer, then loosen and remove the castle nut and the thrust washer. In order to hold the hub from turning when loosening the nut, insert a drift through the caliper and into the rotor vanes. Remove the brake caliper and support it aside using wire or a coat hanger. Make sure the brake line is not stretched or damaged.
Remove the brake rotor from the wheel hub.
Remove the bolts retaining the hub/bearing assembly to the knuckle, then carefully pull the assembly from the splined end of the halfshaft. If available, use J-28733-A or B, or an equivalent spindle remover to prevent damage to the shaft or hub/bearing assembly.
Remove the cotter pin from the drive axle end nut and retainer
Remove the retainer for access to the end nut
Loosen the drive axle nut-here the caliper is installed so a drift could be inserted to keep the disc from spinning
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.
All the Ford Escapes (thru 2011) have a Gen1 cartridge type bearing on the front. I'm pretty sure that the bearing is also the same for all Escapes; FWD and AWD, V6 and I4. I'm not sure, but I suspect the Hybrids are the same also.
The Gen1 bearing is difficult to replace yourself unless you have access to a hydraulic press.
The bearing has a press fit into the knuckle and the wheel hub. For most people, I would recommend the dealer or a decent shop.
If you're brave, here are the shorthand steps to replace the bearing:
Remove the wheel/tire.
Remove the brake caliper and rotor.
Remove the ABS sensor. It's a small bolt, be careful.
Remove the axle nut and press the axle shaft out (You should use a special tool for this) Beating it with a hammer is NOT recommended and will damage the axle threads. It's not stuck or rusty, the spline on the axle has a slight Helix that locks it to the hub.
Remove the lower ball joint. Do this first, while the strut and tie rod are still connected, because you might have to really work it over. Remove the cross (pinch) bolt and nut. Pull the ball joint out. If stuck, you may have to open the pinch joint a little with a punch or chisel.
Remove the tie rod nut and the tie rod from the knuckle.
Remove the 2 strut bolts.
I'm pretty sure that the knuckle/hub assembly is now loose, then:
Press the hub out of the bearing. Half of the inner bearing race will be stuck on the hub.
Press that inner race off the hub. Maybe a "bearing splitter" will work.
Remove the snap ring from the knuckle.
Press the rest of the bearing out of the knuckle. It's OK to press against the inner race; you're going to replace it anyway. (Note: whatever you're doing, don't try to save the bearing. Don't.)
The new bearing can be installed either way; it's symetrical.
Press the new bearing into the knuckle. Press on the outer race only! Do not press across the inner race. You can use the old outer race as a press tool. Do not damage the seal retainer or seal.
Insert the snap ring. Make sure it's fully seated. Check it again.
Press the hub into the bearing. Do NOT press thru the knuckle (and the bearing) as a base. You must support the bearing at the inner race. Using the knuckle will damage the bearing, and you'll be doing this all over in about 500 miles.
The knuckle can be reinstalled on the vehicle in whatever order you want, but I recommend putting some grease on the spline and put it on the axle first and hand start the nut. You can torque the nut later. The axle nut torque is 300Nm (220Ft-lbs).
Remove wheel. Take off outer driveshaft nut. Remove lower ball joint
pinch bolt & separate ball joint from spindle. Pull rotor &
spindle out & away to pull driveshaft outer splined end out of rotor
center hub. Look on the back of the spindle for the 4 bolts that hold
in the wheel bearing. Use a 12 point socket to remove the 4 bolts and
remove wheel bearing from spindle (out towards the wheel stud side).
Probably will have to use a air chisel to get it out. Once it's out undo
the 4 bolts on the outer (wheel stud side) of the rotor and remove the
rotor from the hub. Clean & lube the hole where the bearing was in
the spindle & the inner face of the hub. MAKE SURE IT'S CLEAN
otherwise you may get a pulsation on braking if theres a piece of rust
or dirt between the rotor center & the hub face. Reverse procedure
If the rear bolts don't come out then you will have to use a
slide hammer to separate the bearing to replace the rotor and there is a
very good chance you will need to replace the wheel bearing after
you're done (noisy on road test).
Not the job to do at home,
usually an easy 2-3 hours per side if things go bad (book time is 2.2
hrs per side). Use good quality rotors as you don't want to have to do
it again because a cheap rotor gave you a pulsation.
the rear bearing is pressed into the hub so take the hubs off and take to a engineering shop to have the new one pressed in ,now the front ones are similar in as much as they need pressing in and out ,DO NOT TRY TO DO IT WITH A BIG HAMMER ,its dangerous ,remove the wheel trim and slacken the big nut in the middle ,think its a 32mm then jack vehicle up remove the wheel ,undo the brake caliper by the 2 bolts that hold it to the stub axle ,slacken bolt on track rod end but do not remove fully and then wack the end of the stub axle where the track rod end goes through .One good wack with a 1kg hammer will do it on the end of the steering /stub axle shaft without damaging anything because you have left the nut on loose.then remove the bottom track control arm pinch bolt it has a star head and a 17 mm nut on the other end ,use a lengh of scaffold pole or a big crow bar to pull the track control arm down so the ball joint come apart ,take the stub axle off and in the back is a big circlip but leave it alone and just take it to the engineering shop ,its very dangerous to try to remove the bearing with a big hammer and drift because it can and will chip and hit you in the face trust me on this
Removal:Raise and support vehicle. Remove wheel. Remove caliper assembly. DO NOT allow caliper to hang from brake hose. Always support caliper by wiring it to frame. Remove rotor. Loosen and remove ABS speed sensor mounting screw. Carefully remove sensor head from steering knuckle. If sensor head is seized due to corrosion, use hammer and brass punch to tap sensor. Tap edge of sensor ear, rocking sensor from side to side until it is free. DO NOT use pliers on sensor head. Remove axle shaft nut. Remove 3 bolts securing hub assembly to steering knuckle. Pull hub straight back from knuckle. If hub is corroded, pry between hub flange and knuckle
Fully remove knuckle pinch bolt. Insert pry bar between lower control arm and steering knuckle. Push down on pry bar to separate ball joint stud from steering knuckle. Ensure ball joint dust boot is not damaged during removal. Loosen and remove strut-to-knuckle nuts. Bolts are serrated where installed into knuckle. DO NOT turn bolts in steering knuckle. Use soft-face hammer to drive bolts out of knuckle. Remove knuckle from vehicle.
